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

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.

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

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

Multimedia and ComputerLab Integration
Pedagogical aspects of the learning environment
• New teacher strategies
• Use of resources
• Professional development
• Advanced preparation
• Simply put, this means ...
Copyright 1999 © Professional Systems Engineering
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!
Copyright 1999 © Professional Systems Engineering
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
Copyright 1999 © Professional Systems Engineering
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
Copyright 1999 © Professional Systems Engineering
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

Sights and Sounds
Target your audience
• Military, INFOCOMM, or Girlscouts
• Visual > ~10% persistence of memory
• Auditory > ~40-50% persistence of memory

Question?
What do George Lucas and
INFOCOMM have in common?
Copyright 1999 © Professional Systems Engineering
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)

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

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
