(IDVN)
CONSIDER . . . . .
How your research, education, and
teaching processes would change if you
had . . .
access to a national or global multichannel
broadcast video network
thousands of specialized information channels
content specifically designed and tailored for
small common communities of interest
quality equal to or better than today's television
Key Issues
Education and research requirements
mandate specialized communications
services in both content and audience
Specialized communications requires
tradeoffs of cost and quality
More specialization results in higher
overall costs
Cost pressures result in bias toward
mass audiences
IDVN Technology Characteristics
Connected from campuses to MREN to vBNS
Multicast enabled
Java based "DV Guide" for programming
schedule
Real time encoding at 1.5 mbps minimum
NT servers at each partner station running IBM
Videocharger server
IDVN Channel Candidates
Health Care (National Institutes of Health)
Government Services (NASA, ES)
Education (Universities)
Reference Material (Video Encyclopedia of
2oth Century, Destinos)
