What is IPTV?
Basic IPTV:
>Standard Def. Television (SDTV)
>High Def. Television (HDTV)
>Local programming
>Video-on-Demand (VOD)
>Interactive program guide
>Music channels
>PVR
• IPTV (Internet Protocol Television) describes a system where a digital television
service is delivered to subscribers using the Internet Protocol over a managed
broadband connection.
� Beyond Broadcast TV & Films (Cable/Satellite/Terrestrial),
in terms of its interactive real-time control and material selectivity
� Beyond Video Download over the Internet,
which is not necessarily real-time
� Beyond Best Effort Video calls over the Internet,
which is without quality controlled
5
Integrating services with Television
• It is possible to integrate a number of services directly with the Television content, such as:• Telephony services
• Advertisement
• Emergency alert
• Web services
• Interactive Voting
6
How big will the IPTV market be?
• The worldwide IPTV Service Revenue is forecasted to reach U.S $38 billion in the
year 2009.
• The worldwide IPTV subscribers are forecasted to reach 53 million in the year
2009.
• The Americas and Western Europe are expected to be the biggest markets in
terms of revenue per user basis.
• China will be the future IPTV dragon due to rapid urbanization, fast growing
economy and expanding middle class.

IP Unicast versus IP Multicast
• IP Unicast is the way how Internet currently works.
• It is point to point
• Consumes huge amount of bandwidth/resource for multimedia applications
• IP Multicast is the way how IPTV network delivers video content.
• It is point to multi-point
• Consumes less bandwidth/resource, since streams are replicated
on the network rather then server.

Pieces. What builds up the IPTV puzzle?
• A number of components operate together in a such manner that provides end to end video solution:
• Content feeds• Video content (Analog or Digital).
• Encoders/transcoders• Encodes/transcodes the input into a format
suitable for IP delivery(Mpeg-2/H.264).
• Encrypters• Secures the content and provides
DRM (Digital Rights Management).
13
Pieces. What builds up the IPTV puzzle?
(Cont’d)
• VoD (Video On Demand) Servers• Stores on demand video content and sends to interested parties.
• EPG (Electronic Program Guide) Provider• Provides easy to navigate/programmable TV Guides.
• Middleware• This core component stores:
• Subscriber data,• Channel information, • EPG data,• STB (Set Top Box) information.
• Provides communication between other building blocks.
14
Pieces. What builds up the IPTV puzzle?
(Cont’d)
• STB (Set Top Box)
• The consumer device connected to Internet,
• Gets the content stream, decodes the content
and sends it up to the Television,
• Provides user interaction with the Television,
• Stores recorded content if has PVR
(Personal Video Recorder) capability.
• DHCP(Dynamic Host Configuration Protocol)Server
• Distributes the IP addresses to STBs,
• Sends the video head end connection
information to STBs.

• Scanning Method
• Interlaced (i): Odd lines refreshed on first pass, even lines on next pass• Each pass is called a “field”
• Progressive (p): Entire screen refreshed in order
• Refresh Rate
• Number of times per second that screen image is fully replaced
• Generally determined by power source

16:9
• All analog television standards use 4:3 aspect ratio
21
Digital TV
• Total image resolution displayed in DTV and HDTV is referred to in terms of number of pixels
on the screen rather than lines.
• The four vertical scan line systems used in digital TV are:
• 480p (480 lines vertically scanned in a progressive fashion),
• 720p (720 lines vertically scanned in a progressive fashion),
• 1080i (1,080 lines scanned in an interlaced fashion).
• 1080p (1,080 lines scanned in an progressive fashion)
• Standard Definition Television (SDTV) refers to digital transmissions over
480-line resolution, either interlaced or progressive scanned formats.
22
HDTV
• High-Definition Television (HDTV) is the high-resolution subset of our DTV system.
• 16:9 image with twice the horizontal and vertical resolution of our existing system, accompanied by 5.1 channels of Dolby Digital audio.
• HDTV generally defines, an image with 720 progressive or 1080 interlaced active (top to bottom) scan lines. 1280:720pand 1920:1080i are typically accepted as high-definition scan rates.
23
Standard Definition (SD) vs. High Definition (HD)
• An MPEG-2 SD video transmission can range 3-6 Mbps
depending on the type of content.
• This same content transmitted using HD resolutions will
need from 12-20 Mpbs of bandwidth.
24
Access Networks and High Definition
• ADSL can deliver up to 8Mbps of bandwidth but not provide sufficient bandwidth for HD content.
• ADSL2 can deliver 11Mbps which is roughly sufficient for a single HD stream.
• ADSL2+ can support a theoretical maximum of 24Mbps of multiple HD streams.
• VDSL, a costly alternative, is able to provide 52Mbps.
• Fiber, with its 100Mbps, provides a complete solution for the delivery of multiple HD contents to the subscriber's home.
25
Why to compress the content?
• SDTV (NTSC):
Standard screen
640 pixels x 480 lines x 24 bits (3 x 8) x 30 frames/sec = 221
Mbps
• HDTV:
Large screen1920 pixels x 1080 lines x 24 bits (3 x 8) x 30 frames/sec =
1.493 Gbps
26
Mpeg-2
• MPEG-2, published as a standard in 1994, is a high-bandwidth encoding
standard, supporting a bandwidth range of approximately 2Mbps to more than
20 Mbps.
• MPEG-2 Was expanded to encompass HDTV requirements at app. 12-20
Mbps.
• MPEG-2, a lossy video compression algorithm, compresses video data at ratios of 70:1 to 100:1 depending on the type of content being compressed.
• Now the required bandwidth for video transmission is roughly 4Mbps for
SDTV and 12 to 20 Mbps for HDTV.
27
H.264 (Mpeg-4 Part 10)
• Recently, we are witnessed the emergence of MPEG-4 (the H.264 flavor), an improved compression algorithm adopted by the broadcasting industry providing video quality similar to MPEG-2 at roughly one half the bit rate.
• MPEG-4 arose from a need to have a scalable standard supporting a wide bandwidth range from streaming video at <64 Kbps, suitable for Internet applications, to app. 4 Mbps for higher-bandwidth video needs.

What is Agile
43
Beginning with the Agile Manifesto…
Official definition from the Agile Manifesto lives here: www.agilemanifesto.org
"We are uncovering better ways of developing software by doing it and helping others do it. Through this work we have come to value:
• Individuals and interactions over processes and tools
• Working software over comprehensive documentation
• Customer collaboration over contract negotiation
• Responding to change over following a plan
“That is, while there is value in the items on the right,
we value items on the left more."

Why Agile?
- speaks directly to the bottom line
• Predictability…Easier to manage project scope, predict TTM, fewer ‘big late and bad’
• Shorter iterations, Continuous Integration, Continuous Feedback
• Customer Appeal…Clear measure of progress
• Story based requirements, More opportunity for customer involvement to suggest feedback and innovation
• Quality …Done-done at the end of each Sprint
• Tests match the actual usage, less to test per iteration, clear ownership
• Maintainability…Clear business requirements and incentive to keep design simple
• Prioritized list, constant integration, more cycles to eliminate potential problems
