Assumptions

Assumptions

  • Computation cycles are free

    • Install multiple computers to provide services

  • Bandwidth will be free

    • Think about new uses of bandwidth

  • Use of the Internet

    • Publication – the web

    • Communication – email, newsgroups, chat, etc.

    • Shopping transactions


Problems or opportunities

Problems or Opportunities

  • Poor audio/video quality

    • Improve algorithms, use more CPU cycles, and use more network bandwidth

    • Larry’s mantra: “multiple video streams with varying quality”

  • Too complex to setup and use

    • Install permanent facilities

    • Automate common operations

    • Build gateway services to support alternative technologies

  • Too expensive

    • Ride technology cost curve

    • Look for integrated solutions


Research problems

Research Problems

  • Audio processing

    • Audio balancing, noise reduction, echo cancellation, spatial imaging, etc.

  • Seamless interaction

    • “Sense of Presence” – see all participants

    • Floor control – as easy to learn and use as raising hand


Problems cont

Problems (cont.)

  • Production automation

    • Start/stop

    • Camera control/stream switching

    • Special-effects processing

  • Scale to large conferences?

    • 4-up video composition for small conferences

    • Webcasts for large conferences

    • Something else between?

  • Support more dynamic operation


My opinion

My Opinion

  • Access Grid is emerging standard

    • More flexible than H.32x conferencing

  • Hard problems

    • Operation and control

    • Remote participation

    • Audio support and processing

  • 10-20 years from now…

    • N-way videoconferencing will ubiquitous like telephones
