The blamegame

What could have been a relatively smoothtransition to digital television is turninginto an all-out political war. The recentmovie title, "There Will Be Blood," might

best describe what is starting to happen.In early January, FCC chairman Kevin Martin reminded

everyone that no matter what industry issues might arise,Feb. 17, 2009, was going be a hard deadline because, "Weget to reclaim that spectrum." In other words, Congresswants that money, so shut up and play ball.

By mid -January, Democrats John Dingell and Ed Mar-key began building a protective firewall for themselves andcolleagues by announcing that DTV transition hearingswould begin Feb. 13. "With just a year to go, we want thistransition to be as smooth as possible for American con-sumers?' Markey said.

In response to President George W. Bush's request toblow another $20 million on the FCC's DTV educationprogram, Dingell moaned, "I'm concerned about the sizeof the increase. When added to the original $5 million thatwas allotted by the Republican Congress that enacted thisprogram, this is far too little to educate a nation of 300 mil-lion people. We should not be attempting this transitionon the cheap?' Translation: "Don't blame Congress if thisdoesn't work. We held hearings."

In this bitter climate of political debate, it's also not sur-prising Dingell saddles a "Republican Congress" with theresponsibility for the program.

By early March, FCC commissioner Michael Coppswas screaming about the sky falling and comparing thedigital transition to a Broadway play. What? The truth is,he's positioning so he can say, "I told you this wouldn'twork, so now make me FCC chairman" with a futureDemocrat White House.

About the time the STBs were to arrive on store shelves,the Community Broadcasters Association (CBA) beganwhining because some of the STBs do not provide foranalog signal pass through. In other words, the associa-tion's lower power (analog) stations won't be receivableon these boxes.

A collective, "Oh, my gosh! How could that happen?"with a sly wink, wink, could be heard and seen from theNAB and MSTV.

The CBA's vice president of technology, Greg Herman,said, "Distribution of the boxes, in our opinion, may wellbe illegal?' Oh boy, call out the lawyers.

Another example of key people ducking for cover wasthe unexpected departure of NTIA's point person on thewhole converter box program, Meredith Baker. Becauseshe's held the job only since last November, you have towonder if she knows something's up and wants to be longgone when it happens.

But don't worry. Our fearless FCC chairman has devel-oped a solution. On Feb. 12, Martin issued a request forindustry -wide cooperation to help LPTV stations reachtheir viewers.

He's decided DTV stations should voluntarily partnerand carry the signals of their local LPTV stations on oneof their digital multiplex channels. He was kind enough tosay that full -power stations could be reimbursed for theircosts of carriage.

So, the blame game has begun. Congress has held hear-ings proclaiming that insufficient money was spent. TheNTIA says the rules were clear. The FCC says full -power sta-tions should carry the LPTV signals. The CBA says it maysue. And NAB and MSTV say, "Tisk, tisk, such a problem?'

Bureaucrats and politicians are good at only two things:spending our money and avoiding blame. The DTV con-verter box program may well just be the latest example. BE

The second time aroundCan broadcasters fall in love withunlicensed white space devices?

In his book, "Defining Vision:The Battle for the Future ofTelevision," reporter Joel Brin-kley tells how the drive for ad-

vanced television has its roots in anFCC proposal from the '80s, whichrequired broadcasters to share ad-ditional broadcast white spaces withthe land mobile industry. In an ef-fort to hang onto their precious fre-quencies - and inspired by JapaneseHDTV experiments - the broad-casters struck a new plan.

They said they needed the unde-rutilized spectrum space for HDTV.Brinkley's book describes the discus-sion that ensued at that NAB meetingin 1986. An unidentified participantin the meeting reportedly raised aconcern, "Yeah, but what if we reallyget it?"

Wish grantedUltimately broadcasters did get the

opportunity to deliver HDTV to themasses. Rather than using two 6MHz

So here we are 22 years later, andbroadcasters are finally facing theend of the analog TV era. However,the debate over appropriate uses ofthe white spaces in the compactedbroadcast TV spectrum (channels 2through 59) still rages on.

It's like déjà vuSeveral factors have historical-

ly contributed to the need for thebroadcast white spaces. First andforemost, the use of high-poweredTV transmitters on tall transmis-sion towers cause signals from thesetransmitters to radiate into adjacentTV markets.

This is particularly true for geo-graphic areas with high populationdensity and multiple adjacent mar-kets, such as the northeast corridor

between Washington, D.C., and Bos-ton, as well as in Southern Califor-nia. Many channels cannot be usedin adjacent markets because of in-terference considerations, and thislegacy has been perpetuated with thenew DTV service.

Second, the RF design of legacyanalog TV receivers was limited inthe early days of broadcasting. Thelack of sensitivity in early TV tunersoften required that several adjacentchannels not be used to protect theone channel carrying a TV broadcast.Modern TV tuners offer improvedsensitivity, as evidenced by the ATSCrecommended practice A-74, whichdetails minimum receiver perfor-mance guidelines.

And finally, the propagation prop-erties of certain frequencies in the TVbands, and reserved use for other ap-plications, such as radio astronomy(channel 37), require the designationof additional taboo channels.

Let's open upIn 2004, the FCC issued a notice of

proposed rulemaking (NPRM) thatwould open up the white spaces fornew uses. The commission proposedto classify unlicensed broadband de-vices to be used in the TV bands intotwo general functional categories.

The first category would consistof lower power personal/portableunlicensed devices, such as Wi-Ficards in laptop computers or wire-less in -home LANs. The second cat-egory would consist of higher powerfixed/access unlicensed devices thatare generally operated from a fixedlocation and may be used to providea commercial service such as wirelessbroadband Internet access.

Unlicensed permissionIn October 2006, the FCC issued a

report and order and further noticeof proposed rulemaking (FNPRM)for new uses of the white spaces.(See "Web links" on page 20.) Thisorder authorizes the fixed/access un-licensed devices mentioned above.Service may begin Feb. 18, 2009.

After the first NPRM was issued,the IEEE began work on a standardfor these fixed point-to-multipointsystems. The IEEE 802.22 standardis currently going through the finalphases of documentation and adop-tion. (See "Web links:')

The FNPRM extended the op-portunity for comments and test-ing of portable devices that woulddetect the availability of unusedchannels allowing their unlicenseduse in the TV bands. Two such pro-totype devices were tested last yearwith mixed results. A second roundof tests are currently underway withfour prototypes.

accommodating the unnecessarilyrestrictive (and spectrally inefficient)recommendations of self -interestedspectrum incumbents.

Love the one you're withObviously the debate over li-

censed vs. unlicensed uses of ourscarce spectrum resources is steepedin history. It also has strong ties tothe issue of government protectionof the monopolies and oligopolies ithas created via regulation of the tele-communications industries.

The breakup of AT&T serves as anexcellent backdrop to the white spacesdebate. Prior to the breakup of AT&T,

The debate over licensed vs. unlicenseduses of our scarce spectrum has strongties to the government protection of themonopolies it has created via regulationof the telecommunications industries.

Yea vs. nayPredictably, the NAB and the

MSTV strongly oppose the use of un-licensed portable devices in the TVbands. (See "Web links.")

Several organizations are pushingfor the unlicensed use of the whitespaces. The New America Founda-tion has issued several reports andhas filed comments with the FCC inresponse to the white spaces NPRM.(See "Web links.") And several influ-ential information technology com-panies have formed the White SpacesCoalition, promoting the unlicenseduse of the white spaces and devel-oping the prototype devices that theFCC is testing. Members of the coali-tion include Dell, Earthlink, Google,HP, Intel, Microsoft and Samsung.

These organizations counter theassertions of the NAB, the MSTV andother companies that oppose the un-licensed use of the TV bands, claim-ing that it is imperative that the com-mission consider the enormous socialand economic opportunity costs of

the market for telephone devices wasa monopoly for AT&T and its manu-facturing subsidiaries.

The greatest effect of the breakupcame from the regulations that al-lowed any company to manufactureand sell devices to connect to the tele-phone systems operated by the sevenBaby Bells. This not only caused theprice of a telephone to become ex-tremely competitive, it also enableda period of innovation, bringing awide range of new telephones andservices to market. Perhaps the mostrelevant parallel to the white spacesdebate is the birth and proliferationof wireless telephone handsets usingunlicensed spectrum.

The inbreeding of the Baby Bellsinevitably led to their getting backtogether again, after consumers fell inlove with cellular phones they can useanywhere. Unfortunately, not onlydid the Bells renew their matrimonialvows, they managed to create a newoligopoly in the image of Ma Bell.

What is needed is a new businessmodel that delivers bits to things thatmove - not another ISP that pro-vides two-way Internet connectivity,but a system that pushes all kinds ofservices to mobile devices.

It appears that broadcasters are rekindlingtheir romance with devices that use anantenna to pick up their DTV signals.

to deliver TV to fixed receivers in thehome. Its value is tightly coupled tolegislation and regulations that allowbroadcasters to seek compensation fortheir signals from the multichannelcable and DBS systems. Retransmis-sion consent payments are becominga significant contributor to bottom -line profits for TV broadcasters.

As a result, it appears that broad-casters are rekindling their romancewith devices that use an antenna topick up their DTV signals. The ATSCis currently evaluating technologiesthat will support mobile and hand-held devices that require a morerobust modulation standard than8-VSB, which was designed and testedusing the same methodology used bythe FCC for the NTSC standard - anoutside antenna on a 30ft mast.

The mobile standard is expected tobe finalized this year, with the poten-tial that mobile services could beginafter the end of the DTV transitionnext year. The questions: What willthese services be? And how can broad-casters create new revenue streamsfrom them?

What we needDuplication of the legacy free -

to -air TV broadcast model for mo-bile devices does not appear to be acompelling application. Attemptsto create a subscription multichan-nel service hold great interest among

The ability to determine what ser-vices are available and to teach de-vices to capture bits of interest maydepend on limited two-way connec-tivity. If the device is a cell phone or aWi-Fi connected notebook computeror handheld, that back channel mayalready exist.

It would be far more desirable,however, to use the white spaces forthis back channel. Fixed point-to-multipoint ISPs could provide cheapbroadband links to the TV in the fam-ily room. Unlicensed portable devicescould use the white spaces for theback channel and the mobile standardto deliver services, all in the same TVbands using a common tuner.

Perhaps the time has come forbroadcasters to think differently thesecond time around. Broadcastersupport for unlicensed devices thatuse the white spaces could lead to awhole new consumer love affair withbroadcast TV. BE

FCC UPDATEBEYONDTHE HEADLINES

New must-carry rulesThe rules are meant to protect analog viewers.

BY HARRY C. MARTIN

ith the Feb. 17, 2009,digital TV transitiondate approaching, theFCC recently adopted

rules designed to ensure that cablesubscribers who receive analog -onlyservice can continue to view the signalsof must -carry local broadcast stationsafter the transition. These new rules donot apply to broadcast stations carriedpursuant to retransmission consent.

Viewability provisionThe Communications Act requires

cable operators to transmit the signalsof must -carry stations without mate-rial degradation. In its new rules, theFCC interprets this viewability pro-vision to require cable operators toeither:

continue providing an analog tier,but downconvert the digital signal ofmust -carry stations into analog for-mat, or

DatelineJune 2 is the deadline for TV

stations in Arizona, Idaho, Nevada,New Mexico, Utah and Wyoming tofile their biennial ownershipreports.

In the following jurisdictions,June 2 also is the deadline for TV,Class A and LPTV stations that orig-inate programming to place theirannual EEO reports in their publicfiles and place them on their Websites: Arizona, Idaho, Maryland,Michigan, Nevada, New Mexico,Ohio, Utah, Virginia, Washington,D.C., West Virginia and Wyoming.

On June 2, TV stations with morethan 10 full-time employees in Mary-land, Virginia, Washington, D.C., andWest Virginia must electronically filetheir broadcast EEO midterm reports(Form 397) with the FCC.

only provide digital service, trans-mit the signal of must -carry stationsin the digital format, but ensure thatall subscribers (including those withanalog TVs) have the necessary equip-ment to view the broadcast content.

After the DTV transition next year,cable operators will be responsiblefor the costs of any downconversionof DTV must -carry broadcast signals,though they may charge subscribersfor the purchase or rental of set -topboxes necessary for analog TV sets toreceive digital signals. The FCC alsoretained the current requirement that

ability requirements.

Other issues onthe FCC's plate

The commission is also seekingcomment in a further notice of pro-posed rulemaking on several issues,including: how channel positioning rulesshould apply to operators carryingboth the analog and digital versionsof a station's signal; how to properly adjust downcon-verted signals to different aspect ra-tios (16:9 to 4:3);

The FCC is requiring cable operatorsto notify subscribers if they switch

to an all -digital system.

HD must -carry broadcast signals becarried in HD, along with the currentrequirement that such broadcast sig-nals not be materially degraded by thecable operator.

While the commission did not de-fine such prohibited material degra-dation, it specifically declined to re-quire cable operators to pass all digi-tal data in the broadcast signal.

The intent is to give cable operatorsthe flexibility to use digital compres-sion, as long as the average viewer ex-periences the picture quality at leastas good as the quality of any otherprogramming carried on the system.In addition, the FCC is requiring ca-ble operators to notify subscribers ifthey switch to an all -digital system.

These viewability requirementsextend to Feb. 17, 2012, and thecommission will review them duringthe last year of this period in lightof the state of technology and themarketplace. During this transition,small cable systems with an activatedchannel capacity of 552MHz or lessmay request a waiver of the view-

whether material degradation rulesshould apply to stations carried pur-suant to retransmission consent aswell as must -carry; and

additional ways to minimize anyeconomic impact on small cable op-erators while still complying with thestatutory requirements for carriage oflocal TV stations.

The viewability requirements arebeing perceived as a dual -carriagerequirement by many in the cable in-dustry, and some cable programmershave already filed suit in federal courtseeking to overturn the new rules. BE

TRANSITION TO DIGITALDIGITAL HANDBOOK

ATSC enhancementsChanges include standards for mobile

transmission and more.

Now that ATSC is aboutto embark on its sta-tus as the primary TVtransmission method in

the United States, let's take a look ata number of changes to the originalstandard, both implemented and un-der development.

E-VSB provides forenhanced transmission

A new version of 8-VSB called En-hanced 8-VSB (E-VSB) enables op-tional enhanced services, designedto have higher immunity to certainchannel impairments than the mainservice. E-VSB adds FEC coding lay-ers to the data in the form of Reed -Solomon coding and trellis coding.The enhanced data is delivered at areduced information rate selected bythe broadcaster from a set of speci-fied options, including half -rate andquarter -rate coding.

As with any transmission system,there is a trade-off between data rate

19 39Mb/s transport payload =video + audio + services + overhead

and noise margin. For example, a halt -

rate system requires 2n bits of channelspace to deliver n bits of data. Thus,the addition of enhanced services willsubtract from the total data rate byan amount that includes additionaloverhead - a factor not unique toany particular enhancement method.(See Figure 1.)

in real -world conditions confirmedthat the E-VSB bit stream delivers anexpected 6dB margin improvementcompared with the normal stream.Additionally, the tests confirmed thatthe presence of E-VSB did not ad-versely affect the normal stream re-ception of legacy receivers.

ATSC-M/H allows vehicularTV reception

E-VSB, however, did not improveperformance under severe multipathconditions, such as in moving vehicles.For that, a change to the equalizertraining sequence would be needed,and with that, an addition to the stan-dard would be required. Last year,ATSC launched a process to develop astandard that will enable broadcastersto deliver television content and data tomobile and handheld devices via theirDTV broadcast signal. Designed to fa-cilitate the use of the DTV broadcastchannels to provide new services direct-ly to small receivers moving at a highrate of speed, broadcasters will be ableto allocate a portion of their 19.39Mb/ssignal to mobile and handheld whilecontinuing to transmit primary videoservices in the main channel.

A request for protocol (RFP) wasissued last year outlining the new ser-vice and its intended applications. Therequirements for the ATSC-M/H stan-dard include service area and reliabil-ity comparable to 8-VSB, and reliabil-ity comparable to, or exceeding, cellphones and similar devices. In addi-tion, the system must support mobilereception up to at least 75mph. Both

that a receiver equipped with this newequalizer can track rapid multipathfading. The STS provides additionalprotection for the video.

Public details of the MPH systemare still sketchy, with most informa-tion confidential within ATSC. Com-pany materials, however, describe sce-narios using 1.1Mb/s of payload in a4.4Mb/s channel (i.e. 1/4 -rate coding),as well as service with a total allocatedbandwidth of no more than 3Mb/s.This would provide "one quality mo-bile channel and one secondary chan-nel of slightly less quality," accord-ing to company materials Again, it isbelieved that an additional equalizertraining sequence is key to successfulmobile reception.

An Independent Demonstrationof Viability (IDOV) process has beenestablished by ATSC to show that thethree integrated systems under con-sideration can reliably progress toward

implementation. IDOV, a Design forSix Sigma (DFSS) discipline to ensurethe optimal function of products andservices, was endorsed by the OpenMobile Video Coalition (OMVC), anew consortium formed with the in-tent of accelerating the developmentof mobile digital broadcast television.The OMVC alliance encompasses U.S.commercial and public broadcastersoperating more than 420 commercialtelevision stations.

The first phase of the IDOV ac-tivity took place in February inSan Francisco, and an interim reportwas expected the first week of April.Given the not -coincidental timingwith the analog cutoff, a standardswar is somewhat unlikely, so OMVCwill likely endorse one proponent orsuggest a merging if there's a closecall. The OMVC is hoping to launchmobile digital television services by2009, and officials at ATSC say they

are shooting for a candidate standardby first quarter 2009.

FCC updates its rulesIt is not currently known whether

the ATSC-M/H standard will requireFCC rules changes; however, revisionsto the ATSC standards have often re-sulted in updates to FCC Part 73, usu-ally as incorporation by reference.

Last December, the FCC incorpo-rated into its rules the latest version ofthe DTV transmission standard. Thisversion, known as ATSC A/53:2007,differs from the previously used stan-dard, A/53 -B, in several respects.

First, A153:2007 includes the speci-fications for E-VSB for terrestrialbroadcast. It further describes the cod-ing constraints that apply to the use ofthe MPEG-2 systems specification inthe DTV system, including mandatorymain and optional enhanced services.

specifications by revising and clarify-ing the relevant standards. AFD enablesDTV receivers to automatically switchaspect ratios as signaled in the bitstream. Currently, broadcasters are notrequired to carry AFD, but these clarifi-cations are hoped to encourage its use.

ATSC featuresunder discussion

The ATSC Advanced CommonApplication Platform (ACAP) is aninteractive TV (iTV) standard for ter-restrial broadcast, published in 2005.Using Java and JavaTV middleware,ACAP (ATSC A/101) provides a sin-gle method of delivering interactiveapplications to terrestrial and cableset -top boxes by harmonizing theATSC DTV Application Software En-vironment (DASE) standard and theCableLabs OpenCable ApplicationsPlatform (OCAP) specification.

Enhanced AC -3 (E -AC -3) was in-

corporated into the ATSC A/52 -B au-dio standard in 2005. Developed toadd capabilities to multichannel audioplayback, the standard allows for up to7.1 channels, increased compressionquality and extra sample rates. Al-though not backward compatible withexisting AC -3 decoders, an E -AC -3 de-coder is required to be able to down -

convert the output to an AC -3 stream.NRT video delivery is a method

of delivering content to viewers thatis gaining appeal to content ownersand providers. Essentially a methodfor streaming video to viewer storageplatforms, businesses can be built thattransfer content automatically andefficiently. NRT could be deployedtoday, with mostly off -the -shelf stan-dards and existing ATSC services, orwith ATSC-M/H when it is approved.

The ATSC Planning Committeeis also in the process of developingrequirements for ATSC 2.0, which

is envisioned as a complete suite ofnext -generation services for the con-ventional fixed DTV receiver viewingenvironment. ATSC 2.0 might includeinteractive services (ACAP), NRT andenhancements for fixed indoor re-ception, such as new codecs. All ser-vices, however, are planned to havebackward compatibility with currentATSC receivers.

There are also other video modesbeing discussed by the ATSC. Thepossibility of 1080p60 video is gain-ing more interest, as are methods fordelivery of 3-D video to the home.It's hard to believe that the ATSC asa committee is 25 years old this year.Given the rate of technological de-velopment, there's every indicationthat the group will continue to makepossible new television businesses farinto the future.

COMPUTERS & NETWORKSDIGITAL HANDBOOK

Buying a new server?Ask yourself these questions before you do.

Servers have been used inthe broadcast industry fora long time. From the earli-est frame stores and audio

workstations to the latest 3-D effectsrendering farms, they play an im-portant role. In most cases, the con-figuration of the server is set by themanufacturer. But increasingly, endusers are purchasing and configuringtheir own servers as the capabilitiesof off -the -shelf equipment continueto improve. Here are some things youshould consider when purchasing andinstalling your own server.

What is the purposeof the server?

This is the first question you shouldask. Generally, I find two kinds ofservers in broadcast facilities.

The first type is a server dedicat-ed to a task. This server may be de-ployed as video/audio storage systemor graphics rendering farm, or it maybe dedicated to more general net-working tasks such as e-mail gatewayor a firewall.

The second type of server is a

catch-all server, handling several taskssimultaneously. For example, it maybe an e-mail server, a shared storagesystem and run a couple of databases.Whether a server is dedicated to a sin-gle task or it is performing several dif-ferent tasks, it is important that youunderstand what the server is going todo so you can configure it properly.

Who will maintainthe server?

Maintaining a server is sometimesdifficult. Bear in mind that not ev-eryone in a broadcast facility has thesame depth of knowledge as the resi-dent computer technology expert.What happens if that person is onvacation, sick or otherwise unavail-able? What about the hardware? If

there is a hardware failure, can thesystem be repaired using off -the -shelf parts available from the localcomputer store?

If the system can be down for awhile, then there won't be a prob-lem. If, on the other hand, the systemneeds to remain operational, you may

want to consider a server with a war-ranty that includes software supportand on -site hardware support. (Besure that you understand how long itwill take to get a technician on -site.)

What networking demandsare put on the server?

Some servers in broadcast applica-tions will need to handle heavy net-work traffic. Servers handling high-

resolution video are clearly in thiscategory. Servers that run centralizedapplications for several clients may

What are the storagerequirements forthe server?

Ultimately, manyof these estimates end up being edu-cated guesses anyway, and it is a rela-tively inexpensive proposition to addstorage when needed or to replacethe entire server with a new one hav-ing substantially more storage aftera few years have passed. This doesnot mean that you should not thinkcarefully about storage, as the nextpoint illustrates.

How critical is the serverto your operation?

If the server supports an on -airoperation, then you should pay foroptions that will increase the ro-bustness of the server. Relativelylow-cost servers are now availablewith dual power supplies, RAID orother redundant storage mecha-nisms, and redundant cooling fans.All of these options will increasethe chances of your new server re-maining online after a componentfailure. Of course, you should havea solid backup plan for these serv-ers as well. Depending on your op-eration, it may also be necessary to

deploy remote monitoring and di-agnostics in the servers. (What hap-pens if one drive in the RAID fails,no one notices and then you lose asecond drive?)

What operating system willyou use on the server?

I know that for many of you, thetopic of server operating systems(OS) borders on a religious discus-sion. For that reason, I am not goingto get into any specific recommenda-tions. That said, for most applicationsthere are three choices: Microsoft,UNIX or Linux variants (*nixes), andMac. The choice may be driven byserver applications or manufacturers'requirements. But in many cases, thechoice really comes down to what youare comfortable with.

If you know Microsoft productsand this is your first server, then gowith a Microsoft server. You can usea lot of what you know about desktopplatforms. If you prefer *nix, I recom-

almost all cases, the computer plat-form for these broadcast applicationsare carefully selected by the manu-facturer. For almost all other applica-tions, yesterday's processors - stillblindingly fast - will work just fine.

Think about it. Will the server beused primarily as a storage platform?If so, it may have high I/O require-ments. But unless all the video mustrun through the processor (which isnot the case in most file servers), ahigh-speed processor isn't required.

How about streaming video on theInternet? Again, look at the wholepicture, both from a processor anda network bandwidth standpoint.If you have a typical Internet con-nection, for example a T1 line, theconnection is limited to 1.5Mb/s.

For almost all other applications,yeseterday's processors - still

blindingly fast - will work just fine.

mend Red Hat Enterprise Linux ifyou are new to servers and will needsupport. If you are comfortable in the*nix environment and want a full -fea-tured, solid, free server, I recommendFreeBSD. If you are a Mac person,then a Mac server is the way to go. Ifyou are used to working at the com-mand prompt level, Apple's *nix OSmakes a transition to Linux or Free-BSD relatively straightforward.

What is the amount ofprocessing required forthe server applications?

In today's computer market, man-ufacturers are always promoting theirnewest, fastest, most expensive server.But spending a few minutes thinkingabout your server and the applicationsit will support may save you hundreds(or thousands) of dollars by purchas-ing yesterday's technology. Only themost demanding applications requiretop -of -the -line processing power.Generally, these are 3-D renderingand compression platforms, and in

Even with five T1 lines dedicated tostreaming, only 7.5Mb/s will comeout of the server to the Internet. At750Kb/s per stream, you could source10 simultaneous streams and still notexceed the capacity of even a single10BASE-T network connection. Justabout any commercial server manu-factured in the last three years couldsupport the processing requirementsof this application. So think about theapplications running on your serverbefore spending a lot of money to getthe fastest processor available.

Specifying, installing and main-taining a server in a broadcast facil-ity is within the capabilities of mostbroadcast engineers. Just pay atten-tion to details, and the installationwill be successful.

PRODUCTION CLIPSDIGITAL HANDBOOK

2GHz transitionWhat still needs to be done?

BY JIM BOSTON AND ROLAND HOFFMANN

This is the year broadcast-ers and Sprint have vowedto accomplish several keymilestones. In response to

the current plans to complete the re-location of all BAS users by August2009, the FCC has allowed an exten-sion to March 2009, and may considera further extension to August 2009.

Some DMA clusters, including top30 markets, have relocated in March2008. This means broadcasters mustbe ready for the cutover or risk mo-bile satellite system interference. In aworst -case scenario, a station couldend up paying for the relocation itself.

Midpoint statusMost stations are halfway through the

eight -phase process, which includes:Phase 1. Market kickoff - 100 per-

cent complete.Phase 2. Inventory submission -

100 percent complete.Phase 3. Inventory verification -

100 percent complete.Phase 4 (halfway point). Quote

submission - 95 percent complete.Broadcasters select vendors, obtainquotes and develop estimates.

Phase 5. Frequency relocation agree-ment (FRA) - 65 percent complete.The relocation contract includes theagreed to quote package. Creating theFRA can take from two to more thaneight weeks.

Phase 6. Purchase orders and ven-dor fulfillment - beginning stages.Many broadcasters negotiate dockswapping at this stage. This is a pro-cess to exchange FRA equipment onthe vendor's dock for something else.Here, stations can trade spare or por-table equipment.

Phase 7. Equipment installation -beginning stages. Stations install theequipment, perform tower work andsystem commissioning and completetheir staff's training. Stations can go

live with digital narrow in place some-times long before the DMA cutover.

Phase 8. Retune and market closeout- beginning stages. Stations in a DMAcluster retune to the new BAS channelplan. If a station has problems, theDMA cluster reverts to the old channelplan and reschedules the cutover. Sta-tions send the old equipment to Sprintfor destruction and settle the final fi-nancial aspects of the FRA.

ChecklistLet's look at some ways to ensure a

positive project outcome. The follow-ing sections will cover antenna andtower studies, filters, LNAs, transmis-sion control and cables, transmitters,receivers, remove slaves and antennacontrollers, spectrum monitoring,central controllers, IFB, fixed links,portable equipment, cutover and im-plementation, and dock swapping.

Antennas and tower studiesSprint generally does not pay for

replacement antennas. The companyonly pays for antennas when filter orremote control issues make it necessary.Stations often need to replace remoteantenna controllers (slaves) to facilitatespectrum monitoring back at the sta-tion or central control point along withstandard telemetry. These slaves oftenare incompatible with existing antennapan/tilt units. In these cases, Sprint mayagree to cover a complete replacement.

Most antennas are slated only forfeed upgrades where the LNA is re-placed with a new phase -stable unitand PCS/AWS filtering.

Some antenna vendors will notbuild filter switching as part of feedupgrades. This means you'll probablyhave to replace the antenna if youneed filter switching. Filter switchingis often needed for Ch 1 or Ch 2 to useduring the transition phase. For thosechannels, you also may need pre- and

post -relocation filter switching. (Seethe "Filters" section below.)

If you are replacing the antenna,be sure the replacement feed hornshave the same polarity as the originalsystem. Also, consider the need for atower study if other equipment willbe added to the tower. Ask the towermanufacturer whether a study is re-quired. If so, Sprint will pay for it.

A note on portable and spare anten-nas: Sprint will generally not pay to re-place single golden rod antennas. How-ever, the company will generally pay toreplace dual golden rod antennas.

If you need a tower study, provide theinformation to your engineering firmearly. The firm will require a lot of data,and it may take you a while to gatherit. The engineering firm will assumethat the tower is in proper plumb andalignment and has correct bolt tight-ness, without significant deteriorationor damage to any components. If youknow of any tower issues, be forthrightand admit them.

FiltersFilters or switches located at ground

level do not constitute a reason for anantenna replacement, because newfilters and switching are installed inthe same location. If this is the case,consider an up sell and pay the differ-ence out of pocket. Then install filtersand switches in front of the LNA. Thatway, the filters will prevent overload-ing and other linearity problems.

Digital modulation provides betterrejection of unwanted adjacent signals,so channel filters may not be needed.However, if your site is close to a celltower, then all bets are off. A cell trans-mitter can radiate 1500W to 2000Wof power, and if close enough to yoursite, problems can develop. Considermounting your equipment higher thanthe cell antennas to reduce the amountof cell RF reaching the antennas.

Stations that use a Ch 1 and Ch 2must install the new BAS filter onlyafter their market cuts over. New us-ers of the abandoned old Ch 1 andCh 2 frequencies will most likely notoccupy the frequencies immediately,so you will likely have time to sched-ule the necessary tower work.

Omni antennas mounted on ENGtrucks use COFDM modulation thatallows trucks to transmit while driving.Diversity receivers at the other endmaximize the chance of recoveringthe signal of a vehicle in motion.Fortunately, COFDM receivers haveincreased ability to recover signalswhere the multi -path characteristicsare changing with location.

Ch 10 users need a special BAS filter.The standard filter combines three par-allel and cascaded filters: the Ch 1 to Ch7 band pass filter, a stop band filter be-tween Ch 7 and Ch 8, and a second Ch8 to Ch 10 band pass filter. To simplifythe filter design, the Ch 10 filter has agentle roll off skirt, making that chan-nel unusable. A special Ch 10 BAS filteradds a brick -wall filter for Ch 10.

LNAsLNAs are commonly powered by

the receiver, a standalone power sup-ply or a power line from the remotecontrol slave. A portable or spare LNAusually does not have a remote controlslave. This requires that new radios beequipped with a diplex kit or that youprovide a standalone bias -T power sup-ply. Many portable and fixed link receiv-ers include it, but some central receiversonly provide this feature as an option.

Transmission andcontrol cables

Antenna control cables have notchanged much since the 1980s. Typi-

cally, this means you can reuse exist-ing cables - unless you change an-tenna manufacturers. Keep in mindthat some of the major vendors' OEMantennas are from the same manufac-turers. However, even if you use thesame manufacturer, the pin -out maychange to support new features. Also,manufacturers sometimes use a serialcontrol protocol to compensate forthe need for more conductors.

If you use fiber on the tower, youwill need new electrical -to -opticaland optical -to -electrical interfaces.Sprint may agree to cover this if theoverall cost is comparable.

Consider your path carefully. Digi-tal LNAs have gains in the 20dB to

ENG receive antennas can be quitecomplicated devices, especially whenfilter switching and other bypassoptions. The authors have seenantennas that can have seven differentconfigurations. Add local serial andparallel control and one or two LNAs,and the antenna can weigh severalhundred pounds.

30dB range. The minimum signal re-quired at the bottom of the cable runis 4dB to 5dB C/N. A 7/8in transmis-sion line has a loss of about 1.86dB/100ft @ 2GHz, and a 1-5/8in line hasa loss of about 1.13dB/100ft @ 2GHz.While the LNA sets the noise floor, theattenuation of the line determines thenoise floor increase at the receiver.

TransmittersA 10W+ analog transmitter will

usually be replaced with a 5W digitalone. A 1 OW or lower power analogtransmitter will be replaced with a1.5W digital transmitter. Digital 5Wtransmitters may require an externalpower amp and revert to lower power

without it. Some two-part transmit-ters optionally bypass the PA from thetruck unit.

If you are replacing a multibandradio, Sprint may have allowed for anew 2GHz radio while disabling theanalog 2GHz part of the old radio.

ReceiversRemote slaves may supply LNA

power. However, if you need the re-ceiver to power the LNA, ensure yourquote includes that option. Anotheroption in most radios is 2-VSB, 4-VSBor 8-VSB. COFDM is better at over-coming multipath effects, but VSBhas as much as a 3dB lower C/N ratiorequirement. If distance is important,VSB modulation is a plus.

If the receiver feeds a transmit-ter, use the ASI feed instead of the IFoutput. The IF output will have moreerrors, and ASI has a fixed 19.3Mb/srate with more FEC.

Remote slave units at the receive sitetalk to the central controller and controlthe receive antenna. These units needto be robust to drive antenna position,filter switching and provide LNA power.They are also used to accept receiverspectrum data and package it alongother receiver and antenna telemetryand send it back to the centralcontroller.

Spectrum monitoringDigital receivers require spectrum

monitoring, so be sure your new equip-ment includes the necessary softwareand hardware. The receiver and remotecontroller protocol needs to be compat-ible to provide spectrum monitoringfeatures. Also, be sure your link sup-ports a fast enough refresh rate to main-tain the spectrum display. This typicallyrequires at least a 19.2Kbaud link.

Do not give up any two-way radiocapability. In some cases, Sprint maypay for continuous duty two-wayradios for IFB. Stations currently us-ing Pro Channel are eligible for ProChannel 3 receivers, which provideside -tone or secondary audio to elim-inate backhaul delay issues.

Cell phone users, keep in mind thatFCC rule 47 CFR 64.402 encourageswireless operators to provide prior-ity access service (PAS) to emergencyresponders. This means that in the fu-ture, you might be covering the biggeststories without cell phones. If that hap-pens, do you have a backup plan?

Fixed linksMany of these issues are also appro-

See us at NAB Booth # N3837.


PRODUCTION CLIPSDIGITAL HANCBOOK

Cutover and implementationYou can move your fixed link to the new frequency imme-

diately after you install the new equipment, as long as it doesnot cause interference. Otherwise, you will have to stay on theold channel until your DMA cluster cuts over.

Before starting installation, discuss your LAN topology,including IP address schema, with your vendors and inte-grator. Provide them with detailed information about anycustom antenna mounts or other unique issues. Schedulethe integrator only after you receive all equipment andhardware, and provide clear dock swap documentation tothe installers.

If you install a BAS filter during the first tower climb, youmust not use Ch 1 or Ch 2 until the cutover. However, youcan continue using the existing PCS filter until after cutover.Then you can schedule the tower crew for a second climb.You will need to schedule the tower crew on cutover week-end to replace channel filters, if you agreed to operate non -switched channel filters in the current band plan.

Once you have a cutover date, coordinate site access,power reductions or off -air time with joint tenants andbuilding managers. Remember to start the license modifi-cation process early. Otherwise, you may delay the cutoverfor the entire DMA cluster.

Dock swappingMost manufacturers allow broadcasters to swap equip-

ment in the vendor's quote for other equipment. Often thebroadcaster will exchange extra spare and portable equip-ment for something now considered more desirable. Thenewly selected equipment is shipped in lieu of the gearoriginally quoted by the vendor to Sprint. As far as Sprintis concerned, it has agreed to give the vendor a certainamount of money based on a vendor's approved quote.Whatever agreement you and the vendor come to for exactequipment is between the two of you.

However, be careful. Some equipment vendors may pro-hibit this process or will charge you hefty restocking fees.The reason is that Sprint has already paid for some equip-ment to be built in advance of actual orders. Now some ven-dors want to minimize the amount of product left on theshelf when this project is completed.

Final thoughtsMany stations are now in a quiet period in their projects

where the FRAs are still winding through Sprint's approvalprocess. Don't waste this downtime. Recheck your plans,and be sure you haven't forgotten something. When it doescome time to move, you don't want to discover that a keycomponent has been overlooked. You will save yourself theembarrassment of holding up everyone in your DMA. BE

builds a

uniqueHO studioBY MICHAEL

GROTTICELLI

For Paul Koopmann, directorof engineering at Versus, aComcast-owned cable net-work, the task of designing

and building a high -definition (1080i)production studio in Stamford, CT,was a welcomed challenge. Versusnationally broadcasts sporting eventssuch as the NHL, Tour de France andProfessional Bull Riding.

Working with a leased space, his en-gineering team needed to install a set,lighting grid, control room, audio suiteand machine room without makingany major structural changes to theproposed studio space. Twelve shortweeks later, as last-minute cable crimpsran through the facility, the engineering

teamhad accom-plished what lookedon paper to be an unat-tainable goal.

For the initial launchof Versus' NHL coveragein October 2005, the network broad-casted from a rented studio in an adja-cent building provided and supportedby Ascent Media Services. Upon the ex-piration of its lease two years later, thenetwork found itself without a homefor its "Hockey Central" studio show.

team deviseda series of in-

novative solutions towork within the con-

fines of the agreement.A giant freestanding box -

truss was erected as a lighting grid androof to avoid major structural altera-tions. The central machine room waspositioned directly above the produc-tion control room and audio suite toallow for less invasive cable runs andcore drills.

CT -based construction company.One of the biggest obstacles present-

ed to the architectural and construc-tion crews was the removal of a fullyoperational glass -sided elevator locat-ed in the center of the atrium, whichwould have to be extracted to makeroom for the set. As part of the net-work's agreement with the landlord, itwould be taken apart and stored. TheI -beams were cut and the elevator car

Soundproofing also provided achallenge, because the exterior atriumwalls are only made of 8ft temperedglass panes. After installing heavy-duty sound deadening panels, trucks,cars and even boats operating justoutside the glass wall cannot be heardinside the studio.

At the heart of the control room is aSony MVS-8000A HD switcher and five46in Sharp PN-465U LCD monitors,which all feed off an Evertz MVP mul-tidisplay system. JVC HD LCD panelswere chosen as program/preset moni-tors for their clarity and native resolu-tions. The monitor wall itself is hungon an adjustable TRAC system, alsodesigned by TBC Consoles.

Wider signal trafficBringing the bandwidth -intensive

HD signals into and out of the bui!d-ing was also a challenge, as the townof Stamford is not equipped to handlewideband transmission. New trencheswere dug from the building at HarborPlaza to the local fiber -optics transmis-sion provider, Level 3 Communica-tions, which is about a half mile away,to accommodate multiple dedicatedOC-3 and OC-48 lines for unlimitedHD capacity. There's also a 48 -jack fi-ber panel installed outside the build-ing on a telephone pole to allow Ver-sus to bring in a satellite uplink truckif necessary. This provides bandwidthto capture live or prescheduled feedsfrom around the world. Signals alsocome in on fiber via Level 3's VenuNet

service and Intelsat circuits.To this day, Koopmann said he's

still awed by what the engineeringteam has accomplished. It completeda project of major proportions, withinan almost impossible timeframe, over-coming obstacles of every nature alongthe way. The network now has an HDproduction infrastructure to rival anyin the industry - where edited videopieces, created within seconds of air,are shuffled between the four floorsduring the live shows with ease. Thetapeless environment it designed andbuilt gives the "Hockey Central" teammore flexibility and better productionvalues than it ever had before. BE

Adjacent channel challengeMany of the advanced perfor-

mance characteristics required ofDTV combiners directly result fromthe allocation of adjacent channelsfor DTV broadcast. Located betweenexisting analog channels, these gapsare the channels preferred by spec-trum authorities around the worldfor DTV, in a quest to optimize spec-trum use. In conventional analogbroadcast applications, interferenceproblems previously rendered theseadjacent channels unusable. The ad-vent of digital broadcast has liberatedadjacent channels, but at a price. Torealize contiguous channels, complexmasking filters - essentially brickwall filters - are required to mini-mize out -of -band products.

The issue of site space constraints,particularly in high -density urban ar-eas, is another practical problem con-fronting broadcasters in many parts ofthe world. Most DTV retrofits aim to

realize the extra channels within thespace constraints of existing build-ing leases. The pace of the worldwideDTV rollout demands higher levelsof flexibility and modularity in filter/combiner application. Combiner fil-ters that are tunable - ideally acrossthe entire UHF band- have provento be a major step in this direction.

Early work focused on the high -

power areas (2kW to 100kW). Wave -guide coupling technology was ob-

vert the directional waveguide combin-er for UHF use, and many of these arepatent -protected. In this arrangement,the two perfectly matched filters in abalanced combiner are effectively real-ized in a single circular waveguide as-sembly. Similarly, careful design of thewideband waveguide path (the spine)has provided dramatic improvementsin frequency span.

viously the preferred method to ac-commodate such power levels. Con-ventional waveguide UHF combinersystems posed limitations becausethey were large and bulky, and capa-ble of handling less than 20 percentfrequency span, which limited thescope for future channel additionsoutside this span.

Also, adjacent channel combin-ing demanded waveguide filters ascomplex as eight -cavity (eight -pole).These could be as tall as 13ft, whichis often too large for many rooms.To overcome these problems, a direc-tional waveguide combiner -a wave -

guide filter technology often used inmultichannel multipoint distributionsystems (MMDS) - can be used. Sev-eral innovations were required to con-

mance while using the shorter six -poleassembly. The result is a particularlycompact waveguide filter/combiner,which is about half the size of conven-tional waveguide combiners, yet offersa frequency span of around 46 percent.This allows two models of the direc-tional waveguide filter to accommo-date the entire UHF frequency range.

The pace of theworldwide DTVrollout demandshigher levels offlexibility and

modularity.

This compact waveguide filter/coni-biner technology is now being usedacross North America, Europe andAustralia, where larger power broad-cast sites are more common. The mostnotable application of this technologyis the combining of 14 high -powerchannels for three antenna systemson the Sears Tower in Chicago. Usingdirectional waveguide combiners, thiswas achieved in a room with a foot-print of 23ft x 23ft.

COUNTDOWN TO 2009SYSTEMS INTEGRATION

Multi -image displaysControl rooms are turning toward multi -image

displays to replace traditional monitoring.

In the early 2000s, companiesthat provide multi -image dis-play technology started to offerseveral new improved variants

to the broadcast industry. Their pri-mary targets were control rooms andpresentation suites in master controlfacilities for the display of multiplewindows of video, audio and data onunified screen monitors. Previously,because of concern about reliabilityand unstable pictures, many broad-cast engineers shunned the idea ofmulti -image displays.

But, the new generation of high-speed Field -Programmable Gate Ar-ray (FPGA) logic solved most of thoseproblems. Instead of many small CRTmonitors populating a control room,the sight of plasmas and LCDs arebecoming a de facto standard for dis-playing audio, video and data signalsin broadcast centers.

to support the highest capacity ofthe processor's output. When a sig-nal has a resolution that exceeds thedisplay panel's supported resolutionrange, a simplified image will be pre-sented. For example, if the processorsupports up to an SXGA output, thedisplay screen must at least be able todisplay 1280 x 1024 resolution withinits range. Otherwise, the screen can-vas will be a mismatch of the screenrepresentation. Some display screenswill not allow presentation of out -of-range resolution.

As illustrated in Figure 1, the pro-cessor drives the single screen withmultiple windows created on the can-vas. In fact, given that there are mul-tiple windows sharing the XGA (1024x 768) canvas, the resulting windowoccupies less lines and pixels on thedisplay screen.

X=1024 -x 1 -x2

Y=1024 -y1 -y2The SD signal corresponds to the

X- and Y-axis of the canvas. If X startsfrom line 472 and terminates on line15 at the bottom, then it occupies 282lines. Knowing the Y value, then X canbe computed as 376, which results ina picture ratio of 1.33. If the programvideo is encoded at 704 x 480, theprocessor presents it on a simplified376 x 282 form. The artifacts of lessresolution are concealed to the userbecause the image space rendered isa small window (of moving images),proportional to the signal (aspectratio and refresh rate) and occupy-ing less than the real canvas area (re-quired for full -screen display).

Typically, a processor supports onecanvas per screen. In a linear outputconfiguration, the screens are autono-mous of each other. The processor canconceive the target screens as a mul-tiple of solo canvases. (See Figure 2.) Itrepresents four independent canvasesdriven by a single processor.

Note that the proces-sor pooled the horizontal and verticalaxis resolution to obtain the total of2048 x 1536 into one array (doublingthe XGA).

The processoruses specialized hardware to detect abit pattern known as Timing Refer-ence Signal (TRS) framing to recog-nize the SDI data stream. Framingis the process determining where ina serial data stream characters be-gin and end. For SDI, the TRS con-sists of a three -character sequence ofOx3FFh, Ox3FFh and Ox000h in 10 -bithex, respectively. TRS for HD -SDI hasembedded additional Ox00h, Ox000hand Ox000h for a six -word sequence.This TRS can still have SD -SDI TRS

It is possibleto create an unsymmetrical aspect ra-tio in the canvas. However, the resultmay be a misrepresentation of the ac-tual proportion because the processorwill attempt to fill the window with apicture image when it is formed.

Although multi -image processorshave the capability to detect indicationof faults at system level and provide asnapshot of the status of the signal bynotification, they do not lend them-selves to analyzing the signal problemin detail. It is a common misconcep-tion to treat multi -image processors astest -and -measurement devices.

(See Figure 5.)The frame can be fitted with minimalinput modules to handle the requirednumber of sources initially. To ac-commodate more sources, the frameis populated with additional modulesto the maximum capacity. When add-ing a display becomes necessary, anoutput module can be inserted intothe frame to drive more screens.

assigned to any output screens. Thissetting also simplifies deployment andis fairly easy to manage. All cabling in-frastructure terminates in one place. Anadded benefit of this scheme is relatedto the question of screen reliability.Display screens can fail without af-fecting the operation of the remainingscreens. This allows the operator to usethe remaining displays while a faultyscreen is being repaired or replaced.This is often preferred for multiroomapplications, where monitoring perfunctional area is required. (See Figure6 on page 72.)

A single processor is good for a smallimplementation where the number ofsources is static and expansion is fixedto the maximum slot capacity of the

frame. Once the maximum modulesin the frame are inserted, there will beno more room for any future increaseof input sources or output screens.Another problem is that having oneframe means a single point of failure.In the event of a failure, the entiremonitor is completely down.

Distributed architecture employingmultiple processors to drive indepen-dent multiple screens provides highreliability. A failed processor doesnot affect other frames in the system.Each processor acts autonomously,thus providing complete isolation ofscreens connected to it. Distributedprocessing can operate without reso-lution dependencies to other screensin the system because their drawing

canvases can be set individually perprocessor. (See Figure 7.) Distributedsystems can increase input sourcesand screens without interfering withthe other processors' operation.

One major disadvantage of a distrib-uted topology is the source assignment.Because they are not linked together,sources from one processor cannot beassigned to the other, thus preventingthe screen access to those sources.

In designing for full-size NOCmonitoring, the hybrid scheme ar-chitecture of linking multi -imageprocessors is best suited for more dis-play screens and more input sources,yet allows an easy to understandmethod of expansion. The hybridfollows the X and Y plane to allowexpansion of both input (sources)and outputs (screens).

Figure 8 illustrates an example of ahybrid system married to support anunlimited number of sources, and ca-pable of expanding display sources asthe need arises. The processors in thevertical column thread can be expand-ed to an additional number of framesto accommodate more input withoutincreasing the screen panels. Extend-ing the horizontal plane increases thenumber of displays that can be driven'if more screens are desired to renderlarger window images.

Figure 9. Cascaded architecture

Figure 9 shows an example ofmulti -image processor design in cas-caded -tree fashion. The frame P1Aand P1B are allocated as output pro-cessors in 1:1 redundancy. All displaypanels are connected to these twoframes. P2, P3, P4 and P5 are bothdesignated as input processors han-dling input sources only. If P2 be-comes faulty, the only signals affectedare sources connected to that frame.When additional input is required inthe future, additional processor canbe added to the tree.

The biggest drawback in this de-sign is the limitation on the numberof screens that can be driven. Mostprocessors can only handle a maxi-mum of 16 output screens. When sig-nal sources have populated the screenwith so many windows as the inputexpands, the visible images rendered

Second, differentiate input sourc-es and formats. Segregate SD andHD signals sources respectively. Al-though the image processor is ca-pable of accepting both, it is helpfulto know the canvas space a particularsignal will require. Third, envisionthe common design canvas for allscreens. Imagine how the picture willbe presented per display (or formingarrays), including orientation. Thenext step is to choose deploymenttopology following the input for-mats, type, number of sources andscreens, expansions, and reliability.Finally, choose the right multi -imagedisplay processor.

As supply of traditional CRT mon-itors continues to dry up, control

fications and faults triggering usingthe Simple Network ManagementProtocol (SNMP) interface. Most dis-play processors' control software ap-plications can report to a higher -levelSNMP manager or third -party Net-work Management Systems (NMS),thereby improving overall monitor-ing and control workflow.

For instance, when a multi -im-age processor detects alarms and er-rors on its input, it can relay traps tothe NMS manager about the faultysource. In turn, this can run routinesto poll all connected devices to pin-point defective component(s) alongthe chain. This gives the operatorswide coverage of the system statusplus visibility at quick glance.

jitter analysis for HD signalsBY MICHAEL L. RICHARDSON

Serial transmission of data representing videoand audio signals has become standard practiceacross the broadcast industry. There are manyadvantages, including high data rate capability,

self -clocking encoding schemes and acceptance by stan-dards -making bodies. Yet, with these advantages comes anew set of parameters that must be monitored and con-trolled to ensure proper data transmission. Certainly theattributes of the data waveform itself have a major impacton transmission accuracy - commonly referred to asmonitoring of the signal's eye pattern.

However, time -domain monitoring of the eye patterncan only give partial information about one of the most im-portant serial transmission parameters: jitter. Other, moreadvanced testing means are required for full jitter analysis.

Serial video transmissionThe Society of Motion Picture and Television Engineers

(SMPTE) has codified the encoding and serial transmis-sion specifications used in the broadcast industry. Theseare now universally accepted by equipment manufactur-ers, broadcasters and all the intermediate contributors. Se-rial data transmission involves taking the stream of 10 -bitparallel words used in uncompressed component videoschemes and converting that stream to serial.

Non -Return to Zero Inverted (NRZI) is the basic encod-ing scheme used in video transmission. Using NRZI, any

WLEX-TV, the NBC affiliate for Lexington, KY, went on theair with HD news last April. The station uses Harris' VideotekVIM equipment for multiformat test and measurement.

EATUREADVANCED JITTER ANALYSISFOR HD SIGNALS

binary "1" produces a transition in the serial data stream.A binary "0" does not cause a transition. This techniqueis advantageous since it lowers the average transitionfrequency and makes the resulting data stream polarity-

independent.Further encoding is performed using a scrambling poly-

nomial to more evenly distribute transitions in the finalserial stream. A side effect of this process is that certain flatsignals (often a gray or single color image) cause relativelylong periods without transitions in the serial data stream.These signals, referred to as pathological, can cause up to20 -bit periods without a transition.

Parameters influencing serialtransmission integrity

As effective as these techniques are, there are still nu-merous challenges in transmitting data at 270Mb/s or360Mb/s. Bandwidth is even more crucial for HD serialdata transmission, where the data rate is 1.485Gb/s. Theselinks require approximately 2.1GHz of bandwidth tomaintain the data waveform integrity.

Long cable lengths will attenuate the electrical signalamplitude, which can indirectly cause frequency domaineffects. Every piece of equipment involved in serial data

transmission uses a cable equalizer component to auto-matically restore the received signal to nominal amplitude.Unfortunately, these devices introduce noise, which ap-pears as jitter in the equalized data waveform.

While overall jitter amplitude is a crucial factor in as-sessing a serial video transmission system, it is meaning-less without knowledge of what jitter frequencies are pres-ent. Jitter of a particular amplitude will cause differentsystem effects as its frequency varies. The two jitter quan-tities - amplitude and frequency - cannot be separatedwhen analyzing a system; knowledge of one parameter ismeaningless without knowledge of the other.

Common measurement techniquesAny amplitude vs. time display - such as that pro-

duced on an oscilloscope - will supply informationabout the amplitude parameters of a serial data electricalsignal. However, using an oscilloscope to view an eye pat-tern is difficult for a variety of reasons. The first reason isbandwidth. For proper evaluation of HD signals, an oscil-loscope with at least a 10GHz response should be used.Waveform storage is another concern; many data pointsneed to be accumulated in order to view a proper eye pat-tern, and this requires substantial memory.

the ability to display eye patterns. Thedisplay is still essentially that of an os-cilloscope -a voltage vs. time analogwaveform. However, being a video-

specific device, the waveform moni-tor controls are already optimized foreye pattern display.

Advanced measurementfeatures

Some test equipment can exhibitanomalies that yield incomplete oreven misleading measurements. Onesuch area is in the most basic display- the eye pattern itself. Most existingtest instruments perform adequatelywith basic test patterns, such as colorbars. However, many of these sameinstruments do not display some ofthe serial data stream characteristicsthat are unique to the SDI check field(often colloquially referred to as apathological signal).

The receiver equalizer test por-tion of the SDI check field is definedfor HD signals in SMPTE RP178. Itproduces 19 consecutive bit timeswithout level transitions, followed byone bit time of the opposite polarity.(Either starting level can occur.) Thispattern produces a high DC level inthe serial stream. It also produces anasymmetrical eye waveform becauseof this DC offset. Many instrumentslack the sample rate and display per-sistence to properly see this asymmet-rical result. An example of a properly-

displayed test is shown in Figure 1 onpage 84.

Two things are apparent from thisdisplay. First, the single period lead-ing to the high DC offset can clearlybe seen. Second, the effect of this off-set produces middle logic levels whilethe input coupling capacitors arecharging and discharging.

As useful as eye waveform analysisis, it has numerous weaknesses whenanalyzing jitter. While an eye patterndisplay can tell us the total amountof jitter, it gives no indication of jit-ter frequency or jitter variances overtime. Other measurement techniquesare required for these analyses.

Analyzing jitter frequency is essential, because it is acritical part of a system's jitter tolerance. The total amount

of jitter that any system can process with acceptable per-formance is frequency dependent. Systems can usuallytolerate more absolute jitter at very low frequencies. Jit-ter tolerance decreases at midband frequencies (roughly100Hz to 1kHz) before starting to decrease again at highfrequencies outside the response range of the serial receiv-ing circuitry. So, knowing the absolute jitter value is not

In HD systems, thisfrequency is 10Hz. Frequencies belowthis are defined as wander. These rela-tionships also show the overall systemjitter tolerance decreasing as jitter fre-quencies increase.

Selecting an in-house HDformat can sometimes bean easy decision. However,for one network (which

has asked to remain anonymous),making the correct technical decisionproved to be more difficult than theengineering staff expected.

What finally led to the solution wasa simple, yet effective, document: awritten test plan. This test plan gavemanufacturers something to committo (or not). It gave operators, produc-ers, talent and crafts people a way toparticipate. The document provided

engineers with technical work to sinktheir teeth into. Perhaps most impor-tantly, it gave management a tool forevaluating how the selection and im-plementation process was progressingwhile under the gun of an immovableHD launch date. The following is thestory of how that network succesfullyestablished an HD house format.

HD streams vs. filesIt wasn't difficult to select an in-

house streaming video format. Thatwas settled early in the project becausedecisions had to be based primar-

ily on hardware availability. Given thetimeframe and the need to support awide variety of operations, there wasnot enough equipment available thatcould provide interconnects to eitherthe SMPTE 372M or 424M 3Gb/s SDIinterfaces. This led to the selection ofSMPTE 292M 1.5Gb/s for routing anddistribution of 1080i video with em-bedded audio. One downside of the re-quirement for a quick decision is thatit effectively eliminated using 1080p.Today, 372M and 424M are widely sup-ported, so 1080p is a candidate for anHD infrastructure.

FEATURECHOOSING AN HD HOUSE FORMAT

The design processThe broadcast infrastructure was

designed around SMPTE 292M. With-out minimizing the complexities in-volved, the work was straightforward.The network followed manufacturers'recommendations for things like Dol-by E audio subrouting, up/downcon-version to local confidence monitor-ing, and sync and delays.

Unfortunately, when it was timeto choose input and output ports forthe facility's video servers, which wasa seemingly trivial technical selection,the team hit an impenetrable wall.It seemed impossible to select a com-pressed HD file format that would meetthe facility's needs.

By the time the network went livewith HD satellite feeds, it was still un-feasible to order those pesky videoserver ports. This posed a schedule riskworthy of escalation to the executivelevel. (See Figure 1.)

Compressed HD filesThis schedule risk existed for a few

months. It was difficult for the net-work to resolve the trade-offs. Somecompression formats are better for ed-iting, while others are better for trans-mission. Some file wrappers are moresuited for news systems, while othersare better for archive restoration andlong -form production. Certain soft-ware applications and workflows are

Engineer-ing calculated that it could transfer50Mb/s to 80Mb/s files across Ethernetquickly enough, and could install dualnetwork cards into workstations. Lo-cal traffic congestion could be relievedwith a Fibre Channel SAN for day -of-air storage and collaboration. But howwould the network's editing comput-ers perform with large files and highbit rates if they also had to calculatethrough long GOPs?

Editing HD MPEG-2 works betterwith all I -frames, but would the videofrom the new HD studio cameras lookgood enough for all of the network'sneeds? The network also had to weighthe options of either using MP@HLand losing those two color bits (4:2:0)versus 422P@ML and losing the 1080raster size (from 720).

Editing and graphics departmentsnaturally had differing points of view.Some manufacturers offered 422P@H-14 or 422P@HL equipment within thenetwork's timeframe, but these werenot yet demonstrable when integratedat a comparable operational scale withenough proxy generation. Because ofHD file sizes, many network workflowshave to rely on proxy video at least partof the time.

it could collect video quality evaluations

from producers at the same time. Thecombination could help select an in-house HD file format that would workfor everyone. Building a benchmarkplatform was routine, but the networkreali7Pd immediate value from its docu-mentation package. (See Figure 4.)

When the simple edit -in -place testarea was asked to also serve as a place

where video producers could evalu-ate video quality, that larger group ofstakeholders required more coordi-nation and therefore more documen-tation. The following is a list of thatdocumentation and its effects:

and directories.Test sequences. These defined where,

when and how video quality could be,and needed to be, evaluated. Screen -

shots were taken and published, andthis brought to light any software thatwas not ready for testing.

Test results. This included an execu-tive summary, recommendations anddetailed compilation.

ConclusionAlthough the selection process was

arduous, the network relied on a time -

proven test plan process that worked.Surprisingly, it never had to turn on

PASSION ENGINEEREDWhen Baron engineers design a new radar, our passion for weather s always in the

blueprints. No wonder Baron has installed every broadcast dual-pola-ization radar in

the world. For one thing, viewers receive incredibly accurate forewarning if heavy rain,

snowfall and hail. For another, Baron radars are built with the most robust components,

ensuring long-lasting dependability and nigh -powered performance. So viewers get

information that matters, when it matters. Not just any weather vendor can build this

level of meteorological integrity into an instrument as sophisticated as polarimetric

radar. But for us, it was all part of the plan.

Seamless Multi -Format Ingest -to -Air

Workflow Without Transcoding

Bitcentral's Precis open news production system and

the Oasis news sharing and archiving system allows

you to handle your multi -format media assets from

ingest -to -air effortlessly, without transcoding. Both

systems support common formats from cameras,national news servers, .MOV files from creativeservices as well as formats sent in by viewers.

Precis allows you to choose the editing softwarebest suited for your workflow and supports directediting from common high-speed NAS storage. Our

4 -channel HD or SD playout servers support native

playout of all the common broadcast formats. Mix and

match any format HD or SD in the rundown, and they

can play out back to back. The Precis playout also

includes an off -rundown clip store for HD and SDvideo and graphics.

No Barriers NAS vs. Closed SANPrecis uses the fastest NAS for the money-Sledgehammer-

from Maximum Throughput. Compared with a similar

priced SAN, Sledgehammer is four times faster. More

importantly, all users in the station can enjoy fastaccess to any media without expensive fibre channel

connectivity or gateways. So with Precis, you can edit

the same media from common storage with Mac or

PC over Gigabit Ethernet faster than a dedicated SAN.

No Barriers News Asset ManagementStories and camera files submitted electronically or

physically are all managed as MOS objects andtied into the ENPS or iNews assignment function.

Rundowns are integrated into popular edit software

so editors can save their work directly to the story.

The user -intuitive, browser -based news management

application has extremely fast search, categorization

and retrieval of archived media. Because it can

utilize any network storage device (such as spinningdisk) to archive video digitally, the Bitcentral Oasis

asset management system is about half the cost ofdubbing back to tape.

a proxy video, request any story with two clicks and

receive it over the public internet. Oasis providesa whole new way to share news across groups,regions or the world.

Fast Remote Contribution and Productionfor Multiple PlatformsSpecialized UDP software allows submissions from

journalists or viewers over the public internet 2-3times faster than FTP. With just two clicks any story

can be output to multiple platforms simultaneously.

The Precis and Oasis products are built on open

architecture and standards -based technology

which dramatically simplifies the news productionprocess, reducing cost, complexity and time.

The UTAH -400 iPUtah Scientific's Ethernet switch connects real-time

broadcast and the IT worlds.

using the last few years,there has been a con-tinual increase in the useof IT -based equipment

in the broadcast industry. More andmore broadcast devices for storage,manipulation and transport are nowactually computer file -based systems.The industry transformation to whatis essentially a hybrid broadcast/ITinfrastructure has presented somechallenges. Most notable is the issueof how to realize real-time switchingon an IT network that isn't necessarilyreal time.

In simple terms, the signal -specificrouting equipment that has been usedin the broadcast industry basicallymade a direct connection to a pieceof equipment at point A with another

get the guaranteed bandwidth on thenetwork when you absolutely need it?

To solve the problem, Utah Scien-tific developed the UTAH -400 iP net-work switch, which allows for a man-aged Ethernet network with dynamicallocation of bandwidth, QoS andVLANs. The unit is designed to returnreal-time control of the switching fab-ric back to the broadcast engineer.

The problem with networksAn IP network is often viewed as an

inflexible, unmanageable configura-tion that results in performance thatis fixed and has to be "lived with" asit is. Of course, there are methods tocontrol the behavior of the network,but periodic disruptions, such as oneuser on the network consuming a large

piece of equipment at point B (and Cto D, E to F, etc.) without any worryof interference from anything else go-ing on in the system. Now, with the useof the computer file -based equipmentand Ethernet networks for the trans-port of digital video, files are trans-ferred between devices using normal IPfile transfer techniques, and all devicesshare the same pipe. Because of the ex-tremely large size of these files, the timerequired for file transfers can be longand can be affected by the presence ofother data traffic that is present on thenetwork. The challenge is: How do you

amount of bandwidth that results inloss of or impaired use for other users,are considered normal occurrences.

Built into the hardware and soft-ware of industry standard IP switchproducts are various methods tocontrol the behavior of the network.These are used in varying degrees indifferent installations to do thingslike provide for priority of certaintypes of data traffic (video or voice,for example), isolate critical networksegments from noncritical ones, andlimit available bandwidth for non-critical functions. These methods

include the IP type of service (TOS)or DiffSery features to allocate traf-fic priority, VLAN segmentation toisolate network segments, and in-gress/egress queue management tocontrol bandwidth.

To date, these methods can be usedat the system configuration level. Inother words, once they are set up atthe design and installation phase ofthe network, they are typically neveraltered, unless a portion of the net-work changes, and the video engineerin charge of day-to-day operationhas little control of the system. Tomake changes, a system administra-tor would need to modify the setupparameters, and the system then con-tinues on as before. It is a functionalapproach, but it is not dynamic. It re-lies on specialized IT personnel withextensive training to effect changesto the network. Some control param-eters, such as IP TOS, can be madeavailable, but they are not normallyused because of the unwieldy natureof the management.

A new managementmethod

The UTAH -400 iP network switchcan control an IP network in real time,allowing for much more flexibility inthe use of a new or existing IP net-work. Users do not have to live withlimitations designed into their net-work. Traffic prioritization becomessomething that users are allowed tocontrol. Network segmentation canbe changed for daily maintenance orbackup functions on an automatedor manual basis.

Perhaps most importantly, criti-cal functions can be granted priorityimmediately, without interventionfrom an IT professional. And, theadministrator can grant how much



control each user has to assure integ-rity of the network.

With the network switch, networkmanagement can be implementedin a variety of forms, which have allbeen proven in real applications overthe last 30 years. These range from in-dustrial control panels to automationapplications to inband, transfer -by -transfer controls.

Making IT networks workfor broadcast

IP TOS identifiers that managetraffic priorities in a network havebeen in place since the inception ofthe TCP/IP protocol. These methodswork well for prioritizing one type oftraffic over another, but not at deter-mining priority between two or morestreams of the same type of traffic.So, for example, if two editing work-stations are simultaneously trying tomove video files to a server for play -out on the evening news, there is noway to distinguish between and givepriority to the clip that has to go toair in 60 seconds and the one that'snot needed until after the first com-mercial break.

The UTAH -400 iP allows users toprioritize traffic coming from any de-vice to any one of eight tiers that theydesire, in real time. This approachworks well for situations where mul-tiple data streams are competing fora given port's bandwidth. Even whena network is designed with a largebackbone bandwidth, connectionsto individual devices or betweennetwork segments will have a finitebandwidth that can be overrun if itis not managed. With dynamic TOSmanagement, the data stream withpriority can be guaranteed to arriveat the destination port no matterwhat other devices on the networkare attempting to do - so the clipthat needs to go to air in 60 seconds isgiven network priority with a simplepress of a button. And the prioritycan be changed at a moments noticebased on user needs and the chang-ing dynamic of the broadcast day, or

remain in a predefined configuration.(See Figure 1.)

Another management methodavailable on the typical IT networkis the control of VLANs. These arelogically separated paths within thesame physical network infrastruc-ture. They allow users to segment apart of their network away from oth-er parts. Dynamic control of VLANswith the UTAH -400 iP can allow us-ers to segregate a network howeverthey wish, and to change this as dif-ferent needs arise. This managementmethod is essentially the same con-cept as a traditional broadcast XYrouter in application.

in a noncritical activity, and then in-crease it to full bandwidth momentslater when it is involved in a criticaltask. This brings another level of flex-ibility in the behavior of the networkto the end user.

ConclusionMonitoring and managing IT net-

works through the use of the UTAH -400 iP network switch brings a newflexibility to Ethernet networks thatmakes them much more functionaland adaptable to the dynamic realityof the broadcast environment. Theswitch allows for time -critical recon-figuration of any preplanned network

Figure 1. With the UTAH -400 iP, through control of the IP TOS values of the editstation ports, users can control which edit station has priority, and priorities canbe changed through standard broadcast control systems and control panels. Intime -critical applications, this can mean the difference between airing or missingcontent.

Bandwidth, the physical payloadof any given network port, is typi-cally represented as the speed of theinterconnect, i.e., 10Mb/s, 100Mb/sor 1000Mb/s. While this accuratelydefines the maximum speed of theinterconnect, the actual bandwidthcan be modified by limiting the datacapable of being passed over a specif-ic port. Queues within the input andoutput sections of each Ethernet porton a switch can be dynamically band-width -limited at the discretion of auser. This allows a user to restrict datafrom a specific port that is involved

without compromising the function-ality that users are used to now. Theresult is an environment where userscan identify and correct bottlenecksbefore they cause problems. BE

overcome prior limitations.

everal key performance is-sues with multi -image pro-cessors have only recentlybeen fully addressed with

the latest generation of devices. Theseissues include delivering the highestlevel of picture definition across allimage sizes and achieving full flexibil-ity with layouts, without significantlycompromising system scalability.

Delivering picture definitionImage quality for multi -image pro-

cessors is important, especially forproduction studios, which representthe largest part of the multi -imagemarket. Great strides have been madeover recent years with respect to im-age definition andmanufacturers of multi -image proces-sors and by flat -panel display vendors.However, multi -image devices havegenerally been based on off -the -shelfscaler chips designed for use in tele-visions, projectors and other displayproducts. These chips do not deliverconsistently sharp pictures as imagesare resized from partial to full frame.

Display flexibility with respect toimage positioning, repetition andsizing has also traditionally been lim-ited, especially as systems increase insize. This has led to situations in larg-er monitoring environments wherethe operator compromises the layoutpresentation in order to address thesystem's inherent blocking capabili-ties. Multiroom operation brings ad-ditional demands, with the ideal re-quirement for full flexibility at eachoperator position as far as layouts andsource selection are concerned.

To address these issues, MirandaTechnologies developed the Kaleido-X multi -image display system, whichis based on a 7RU frame with up to96 inputs, eight multi -image outputs

and up to 48 HD/SD router outputs.A more compact, 4RU frame is alsoavailable for up to 32 inputs and fourmulti -image outputs. Both versionsuse the company's scaling technology,based on custom chips, to achieve a

high picture quality across all win-dow sizes. Images can be

By using the system's midplane ex-pansion module, two frames can beconnected to allow the display of upto 192 video inputs over up to 12 dis-plays. This configuration provides easyexpansion without losing any of thesystem's extreme signal flexibility, due

to the full interconnectivity

tiny windows to full -screen display,without the loss of definition that iscommonly associated with multi -im-age processors. For operators used toprevious generations of processors,the level of quality improvement isimmediately evident.

Achieving flexibilityKaleido-X addresses the layout flex-

ibility issue with its unique modulardesign, which provides unmatched,high -bandwidth performance. Any ofa frame's 96 inputs can be displayedany number of times, at any size, inany position and on any display, with-out layout restrictions. This enables the

of video, audio and metadata, as wellas time code and control signals.

Multiple processors can be con-nected to create bigger systems bycombining midplane expansion androuter interconnects. This expansionpath offers full scalability, while alsooffering a high level of signal flex-ibility. The processor also offers in-terfacing with third -party routers forgreater system expansion so that thelargest monitoring requirements canbe addressed effectively.

This flexibility extends to multi-

outs, with totally independent controlusing a dedicated remote panel. How-ever, all sources can be shared acrossthe operators to simplify any recon-figuration required, such as to handlemore or fewer channels, as commonlyhappens during night shifts whenthere are reduced operator crews.

Another dimension to the proces-sor's flexibility is its full multiformatoperation, with video accepted usingHD/SD/analog autosensing inputs,and optionally by DVI or MPEG in-puts. The video can be presented in arange of aspect ratios, and the displayscan be either horizontal or vertical.

Operators can make the most of thisextreme flexibility, using either famil-iar mouse control or a compact remotepanel. Simple -to -use, mouse -operatedon -screen drop -down menus are con-textual to speed operations and offernumerous functions, such as changingaspect ratios, checking the safe area,assigning an input and changing textin a UMD. Users can also instantlychange layout configurations and dy-namically zoom one source larger forquality control or audio monitoring ofan on -screen source. Layout creation isalso intuitive, even for complex multi -room setups.

ReliabilityThese advances in quality and flex-

ibility are not at the expense of systemreliability. The Kaleido-X system is

based on a highly robust frame design,with multiple points of redundancyand without a single point of failure forcontinuous 24/7 operation. The 4RUand 7RU frames both use front -load-ing, hot-swappable modules and powersupplies. All the modules are indepen-dent, and there is no single module thatcan cause the system to fail.

The processors also offer multiplefailover scenarios, an easy upgradeprocess, and detailed system statusand logging. They use a real-timeLinux-based operating system, anddata is distributed for redundancy.Each output module has its own pro-cessor, operating system and externalconnections. Therefore, when a newoutput module with a different soft-ware/firmware version, IP address orconfiguration is installed, it will be re-configured automatically by the othercards in the system, without interven-tion from the operator. All these fea-tures mean that the design offers trueresilience for the most critical moni-toring applications. BE

High-power attenuatorsCoaxial Dynamics' solutions provide high average

power and high peak power capability.

Most attenuators on themarket rely on thickor thin film -resistivedesigns screen -print-

ed or deposited on a flat ceramic,much of which is Beryllium Oxide(BeO). This has special handling,processing and disposal require-ments. While the topology is suit-able for lower power, extending at-tenuator performance to more than1kW can be difficult and expensive.

There is another attenuator con-figuration option that provides highaverage power and high peak powercapability at a cost-effective price, us-ing standard, off -the -shelf products.This article explains how to configurea high -power attenuator system from1kW to 200kW for use in high -powerapplications above 1kW with readilyavailable components.

Selecting an RFdummy load

The first step is choosing an RFdummy load for the maximum ratedpeak and average power. (See Figure 1.)Oil dielectric loads are readily availablefor power levels up to 12.5kW. Alterna-tively, forced -air cooled loads, heat ex-changers (self-contained water-cooledloads) or water-cooled loads achievepower levels of 125kW and more. Thisattenuation system will use standarddummy loads, and customization isn'trequired.

Specify the load'sconnector

The second step is to specify the load'sconnector as either 1-5/8in or 3-1/8inEIA flange. The attenuation system usesan intermediate rigid line section that isbased on either a 1-5/8in or 3-1/8in linesize. Choose the intermediate line sizebased on your power attenuation re -

The right panel contains the same oil load with an optionalcooling fan and shroud to extend the power rating above 5kW.

quirements. A 1-5/8in ElA flange con-nector can be used on a load for up toabout 30kW and the 3-1/8in EIA flangeconnector for up to 75kW.

Identifying the flangedrigid line section

The third step involves selectingeither a 1-5/8in or 3-1/8in flangedrigid line section to attach to the load.Once the load's connector has beenspecified, it's time to attach what willbecome part of a coupler/sensor as-sembly: a coaxial rigid line sectiondesigned to mate to the dummy load.This line section can be supplied ina variety of configurations, such assingle, dual or triple socket, but forsimplicity, select a single socket rigidline section with EIA flange connec-tors. Between the rigid line and thedummy load connector a couplingassembly will be needed that includesall the bolts and mechanical hardwareto mate the two flange connectors.

Choosing an RFsampling element

The fourth step is picking an RF

of the load. The elements, called X -Tractors, have a variable set screwto allow for minor adjustments of+/-8dB from their preset couplingvalue of 49dB for the 1-5/8in size and56dB for the 3-1/8in line. (See Figure2.) The attenuated signal output is viaa BNC female connector on the top ofthe element. In theory, it is possible tofurther reduce the signal level by at-taching a standard BNC fixed attenu-ator to the element. The attenuatorshould be rated for 2W.

Deciding on aninput connector

The next step is an optional one:choosing an input connector for the

adapter can be specified up to 6-1/8inline size. Note that an additionaladapter will be required for this por-tion of the assembly.

SummarySpecifying a cost-effective, high -

power attenuator does not requirecustom products, long lead times,multiple vendors or nonrecurring en-gineering (NRE) costs. Standard, off -the -shelf products that are properlymatched together can save projectcost, time and space. BE

ootball is generally con-sidered the hardest -hitting

er - from blazing heat to drenchingrain to ice and snow - this environ-ment is not conducive to tempera-mental electronics. The BaltimoreRavens are among a select group ofNFL teams that operate their ownbroadcasting group. As the locationaudio and postproduction firm con-tracted to provide audio services tothe team, Soundriven has been taskedwith capturing on -field audio for useon the team's television shows.

The Baltimore Ravens Broadcast-ing Department (RAVE -TV) has twoshows on the air. "Ravens Wired" of-fers television viewers a first-hand,on -the -field look at what takes placeduring a game, and it has two seg-ments: "Wired," which follows anindividual player or coach, and "Be-hind the Bench," which focuses onteam activity from the sideline area.The second show, "Ravens Report,"is a sports news program designed togive Ravens fans access to coach andplayer interviews, news about the Ra-vens and related information.

To help ensure trouble -free opera-tion amidst a variety of unknown andunanticipated occurrences, we alsodeploy a Lectrosonics RM remotecontrol with the SMDa transmitteron the wired player. Being able tomodify audio gain, lock and unlockcontrols, or change frequency, hasbeen tremendously important for usbecause asking a player for his pads,pulling everything off to expose thetransmitter and then making adjust-ments is simply not an option. Byusing the remote control, we can ma-nipulate multiple functions withoutany inconvenience. An NFL footballfield can be a hostile RF environment,and while the frequency coordinatordoes his best to assign clear, open fre-quencies, things don't always go ac-cording to plan.

The person respon-sible for charting captures the audioand stamps it with time code.

Asset managementIncrease the value of your future content.

BY JOHN LUFF

Bankers understand assetmanagement. They have alegal and fiduciary duty toprotect assets and be able

to tell you at any moment just wherethey are and what they are worth.They can't abide by estimates nor canthey lose track of them. You would beshocked to hear a banker say, "Yourassets are in a merged account, wethink, but trust me, we will somehowget them out for you."

It is not much different in manybroadcast operations. A station inPittsburgh, to remain unnamed, sup-posedly has archival news film foot-age of Franco Harris' "immaculatereception." This footage is rumoredto be the only actual video that mightprove if Harris really caught the ballbefore it hit the ground.

The content is located in a film can,spliced - as was the custom in thatera - along with all of the news foot-age from that night. It's stored in thetransmitter building, as was this sta-tion's custom. It's safe and secure, in

a location known to a rough degree,though checking to make certainwould prove a challenge. It is possiblethe asset was lost 30 years ago.

If you asked a broadcaster to de-velop a system that could track newsassets, he might have difficulty doingthis. There is no way to search for anasset without rummaging throughboxes of deteriorating original newsfilm. Sometimes, it's even worse atmodern tapeless plants. Recordings

In such a case, the lineage of the shotsis lost, along with any other metadatathat might make it searchable.

Whatneeds to happen to fully protect theasset and its value? One might gliblysay, "use digital asset management(DAM)" software. This is partly true,but not completely.

The asset needs to be available,which in the case of some systemsmeans adding an archive or nearlinestorage system to clear space in theexpensive online system for newcontent. A DAM software systemperforms several tasks. It can catalogthe assets, making the best use of themetadata captured with the contentand allowing additional metadatato be added to enhance the value ofthe content. It can also be coupled toan archive manager, which can useexpert rules to move the content offthe server automatically. In concert,the combination of DAM and archivemanager represents key elements of atotal workflow solution, but not theentire solution.


TECHNOLOGY IN TRANSITIONNEW PRODUCTS & REVIEWS

This is one of the most confusingparts of analyzing and implementingcomplex software systems. Some ven-dors take responsibility for the entirepicture, providing all subsystems andensuring that they interface success-fully. In many instances where endusers picked best -in -class applicationsfrom different vendors and attemptedto get all parties to play nice, there arestories of delays and cost overruns.This results from the attempt to un-derstand all of the variables involvedand manage the complex software in-tegration of the various packages.

Each of the storage elements, aswell as ingest from baseband or filesources, are under the watchful eyeand - in some respects - controlof the DAM manager. (See Figure 1.)The figure shows a secondary pathfrom the low -resolution browse sub-system, which carries browse videoto DAM clients. Using that video,

users can input additional metadataor browse and preview content. No-tice that the archive manager sits at aslightly different level, as it commandsthe movement of content among allof the storage silos. Each of the soft-ware and hardware subsystems is to adegree autonomous. The video servermay also serve content to editing sta-tions or play out to master controlunder automation control, which isnot shown here for simplicity.

There could be multiple servers orarchives attached to the system, butfunctionally, the DAM keeps track ofthe whereabouts of all content, bothin the low -resolution browse andhigh -resolution instances. When it isappropriate to purge content fromthe high -resolution server, DAM canremove it from the low -resolutionbrowse. Or if a copy has been storedin the archive system, DAM might in-struct the browse system to retain its

copy to enable searching of content. Ifan application, such as an edit system,requests a piece of content that is onthe archive, the DAM system wouldinstruct the archive manager to moveit to an online repository for use, al-ways keeping track of each instance ofthe content in a detailed database.

ConclusionCommunication is needed among

all applications to make DAM suc-cessful. An operation done withoutcommunication could leave the assetmanagement system in the dark abouteither new or existing content, quicklymaking the system marginally useful.When this is done right, the complexsystems are more manageable. BE

EOMDEPARTMENT

Viva Las Vegas!Some companies are noticeably absent from NAB.

BY ANTHONY R GARGANO

The premiere trade show eventof our industry - NAB- may be happening as youread this. For manufacturers,

trade shows represent two opportuni-ties: the opportunity to spend moneyor the opportunity to spend moremoney. Well, perhaps there is actuallya third option: the opportunity to savemoney by taking the imprudent actionof not exhibiting.

The growth of NABThis will be my fortieth NAB show.

I have attended shows in Atlanta, Chi-cago, Dallas and Washington, D.C.,but certainly Las Vegas is the premierevenue for this event. I, along with oth-ers I am sure, was delighted when theNAB decided in the 1990s to stop ro-tating the show and fixed Las Vegas asthe permanent setting for the indus-try's annual confab.

Over the years, I mostly attend-ed the show as a vendor but morerecently as an attendee. From thevendor's perspective, I have had theunique opportunity of being one ofthe largest vendors to exhibit to beingone of the smallest - from a multi-million -dollar show budget for Sonyto a multithousand-dollar budget forAgileVision.

During my days as a senior execu-tive at Sony, I oversaw a show exhibitthat for years was the largest at NAB.We purchased exhibit space both onthe floor and off the floor in a quan-tity that could be measured in acres.This trade show is by far the singlelargest fund generator for the NAB,and Sony's expenditures at the showwere hefty enough that they didn't gounnoticed by Eddie Fritts, the thenNAB president and CEO. Fritts wouldcheck with me during the trade showto ensure that all was satisfactory.

Later, I accepted a position as theCEO of a start-up called AgileVision.

Our first year at NAB was in a 10ft x10ft booth, as I recall. Needless to say,AgileVision didn't receive personalattention from Eddie Fritts!

During the past 40 years, the showhas grown from filling hotel ballroomsto now overflowing the 1.9 million sqft of exhibit space at the Las Vegas

post -sale affirmation. When exist-ing customers see you at the show, itprovides that needed psychologicalconfirmation that, yes, they made agood purchase decision. This in turnprovides the subconscious, positiveinfluence that motivates confidenceand generates repeat business.

What's the value of a company'sproducts and technology showcasedto the largest gathering of broadcast

industry decision makers in the world?

Convention Center. The number ofattendees used to be in the low thou-sands and now exceeds 100,000.

"Prudent" fiscalmanagement

This year, several major compa-nies decided not to exhibit at NAB.One major company president whois exhibiting, and with whom I haverecently spoken, said, "Wow! That'sgreat news! I wish more of my com-petitors wouldn't show up." I am surehe was thinking about the increasedopportunity for customer face timeby his sales staff.

As a consummate marketeer, I

could not agree more. What's thevalue of a company's products andtechnology showcased to the largestgathering of broadcast industry deci-sion makers in the world? It's worth awhole heck of a lot in my book. Thosedecision makers can examine a prod-uct in its native environment, andthen walk a few steps and compare itwith a competitor's offering. There'sno better setting for a buyer.

When a vendor exhibits at NAB, fornew sales, the opportunity for boothtraffic, sales closure and new leads isdemonstrable and measurable. Butthere's another aspect, and that is

We are in a somewhat depressedeconomic time (perhaps even moreso by the time this article is in print),and such times always call for prudentfiscal management. But I am alwaysastounded by those companies thatthink the initial prudent step in suchtimes is to severely cut back or eveneliminate advertising and trade shows.Presale customer support and post-

sale customer affirmation are equallyas critical, and such activities are es-sential to the ongoing sales process.

Reduced customer spending meansreduced sales, and that requires ap-propriate cost reductions by manu-facturers. The elimination of adver-tising and trade shows is the easychoice, and it's usually the first choiceof a financial manager.

For those who subscribe to thelatter, I look forward to seeing you onthe NAB show floor. BE
