Things Techies Like to DoBefore or During Vacations

• Look out the ___________ (‘98).

• Hope they don’t catch a ________ before they go.

• Ty-______ one on.

• Plan so it won’t be a _______ drive.

• Pack their __ed, __reen, and __lue underwear.• Making sure the _____ (5) is fed and cared for.


INFOCOMM

System Types

Intranet/Internet digital• Digital-Both LAN and I-net based

• Wired / ISDN / wireless

• Compression necessary

• Real-time limitations

• Digital transmission rates constantly increase

• Lowest first cost because switching (and waiting) is done by the provider

• CAT 5+ cable or Fiber


INFOCOMM

Computer Lab Integration

Define the Purpose, Function and Flow

• Is it a netware or software solution?• Is it a hardware solution?• Is it a hybrid solution?• Is a distance learning application also to be

available?• Assemble the architecture based on building

block methodologies - back to our example.

Preparation


INFOCOMM

The Media Center

Define: Needs / Operations / Staffing• Content

– information - data

– media - CD-ROM, analog, digital• Transmission needs - How far do I go?• Operations flow• Staffing needs• Support space requirements


INFOCOMM

Conforming Software toExpected Needs

Remember: Programming your needs are customized elements to your system

• Scheduling systems

• Softwired remote controls

• Reconfigurability

• Event and connection independence

• Sample programs!

• Broadcast station


INFOCOMM

Acquiring Infrastructureand Systems

Necessary Steps• User programming• Preparing estimates/seeking grants• Dividing the work

– EC/MMSC• Preparing bid documents

– Infrastructure/systems integration• Qualifying bidders• Construction administration• System commissioning

Multimedia and ComputerLab Integration

Pedagogical aspects of the learning environment

• New teacher strategies

• Use of resources

• Professional development

• Advanced preparation

• Simply put, this means ...


INFOCOMM

When, How and Who

• When will it be used?

• How will it be used?

• Who will use it?

• Build it, and they will come!


INFOCOMM

New Teacher Strategies

• Chalk, video, digital

• Distance learning

• Satellite conferencing with interactivity

• Voting and testing electronics

• Independent computer lab instruction

• Prepared “select” demonstrations of broad and

specific topics


INFOCOMM

Use of Resources

• The classroom is no longer a cave in which small

amounts of information are disseminated

• The classroom is a virtual learning space in

which resources from around the globe are

presentable


INFOCOMM

Professional Development

Introduce the users by including them

• Teaching styles and requirements

• Where things are best located

• How things are changed

• What’s it like to be up there


INFOCOMM

Advanced Preparation

Practice makes perfect

• Practice rooms are comfort spaces

• It should work like a phone

• It should be simple to change

• Technology must not interfere with teaching -

it’s an adjunct


INFOCOMM

What Does It Take?

• Production

• Time

• Trials

• Compatibility


INFOCOMM

Sights and Sounds

Target your audience

• Military, INFOCOMM, or Girlscouts

• Visual > ~10% persistence of memory

• Auditory > ~40-50% persistence of memory

Exactly what do we see???

Go to overhead if we have time!

INFOCOMM

Question?

What do George Lucas and

INFOCOMM have in common?


INFOCOMM

Answer

They are both converging on the robustness and acceptance of the

digital media chain!

Recording/Editing/Distributing/Showing (DLP)

(e.g., Star Wars: Episode I - The Prequelin only four theaters in the USA)

(Distribution through the I-net)

The ProblemColor Resolution

• Whites Yellow

• Blue Purple

• Skin Color Faded to Dark

INFOCOMM

Who Should Design Your Systems?

• Professionals with errors and omission insurance

• Trained engineers with communications mastery

• Certification does not equal licensing

• Society registration does not equal licensing– An engineer must be licensed by the state to provide

engineering


INFOCOMM

What We’ve Covered

More than a mouthful• Distribution - local or remote?

• Facilitation - it’s a complex world out there!

• Look~feel~touch…accommodation!

• Prepare for change

• The scariest thing?– Programming in two (2) months - committing is scary
