  • Video Development Initiative
  • An activity of SURA to support member Universities (and beyond)
  • Many projects/working groups
vide activities
ViDe activities
  • Strong interest in video conferencing (H.323 mostly) and video-on-demand issues
  • Deliverables
    • Videoconferencing Cookbook
    • ViDeNet
      • A globally coordinated H323 infrastructure, and recently deployed MCUs in Canada, Australia and Netherlands
    • Work on standards and services
vide projects
ViDe projects
  • VideoAccess WG
    • Standards for video metadata in DC, MPEG7, RDF
  • Rights-L
    • Digital Rights Management, ORDL, XRDL, MPEG-7, …
  • MPEG-4 WG
  • Microsoft Exchange VCS
  • Video Conferencing, and Addressing
  • Data Collaboration
  • Scout (analysis)
vide spin off
ViDe “Spin-off”
  • The MegaConference (1,2,3)
  • 200 sites worldwide (and beyond!) using H.323
  • Tree of MCU’s
  • Delivering virtual conference tracks, virtual quartet, and virtual picnic
  • Became very useful after 11 Sept…

Internet2
  • Many activities described
  • Internet2 Commons
  • VidMid working groups
  • Access Grid (Ok, not I2, but NCSA)
internet2 commons
Internet2 Commons
  • Deliver an I2-wide infrastructure/service, based on ViDe designs and experience
  • Large scale MCUs at OSU
  • Training services
vidmid
VidMid
  • Middleware for video
  • Combination of I2 Middleware WG and ViDe members, and others
  • VidMid-VC: Video-conferencing
    • (H.323, SIP, others)
  • VidMid-VoD: Video-on-demand
  • Issues of:
    • Security
    • Authentication, authorisation and accounting
    • Directory Services
access grid
Access Grid
  • NCSA Grid project
  • Multicast-based, “high-quality” videoconferencing
  • “Integrated” with presentation tools and good quality audio
  • Extensions to collaborative virtual environments
  • Can support many sites simultaneously (30+) with multiple streams from each (5+), and groups of any size at each site.
global development learning network
Global Development Learning Network
  • A project of the World Bank
  • Support the delivery of content into developing countries
  • Content comes from (goes to) Govt, NGO’s, Universities, …
  • Content from around the world
  • Includes policy development, distance education, negotiations
  • Multilingual
  • Cost recovery – self-sustaining.
where is it
Where is it?
  • Africa:
    • Benin, Cote d’Ivoire, Ethiopia, Ghana, Senegal, Tanzania, Uganda
  • East Asia and Pacific:
    • Australia, China(2), Korea, Singapore, Thailand, Vietnam
  • Europe and Central Asia:
    • France, Spain, Turkey, Ukraine

Where is it? (2)
  • Latin America and the Caribbean
    • Bolivia, Chile, Colombia, Costa Rica, Dominican Republic, Ecuador, Nicaragua, Peru
  • Middle East and North Africa
    • Egypt, Jordan
  • North America
    • Canada, Mexico, USA (2)
how is it done
How is it done?
  • 3 satellites (Asia-Pacific, Americas, Europe-Africa)
  • WB Fibre links between the ground-stations
  • Digital/Distance Learning Centres (DLCs) connected by own satellite dish, or fibre to remote satellite dish
how is it done 2
How is it done? (2)
  • DLCs are videoconferencing centres (synchronous activities) and PC labs (asynchronous activities)
  • Support video, data and voice, 256-384kb/s, symmetric.
  • Video is done with H.320 mostly (ISDN/serial based), although some IP gateways.
  • Multi-site events supported through bridge/MCU in Washington
  • 5-10 sessions/day, 18 hours/day.
where is it going
Where is it going?
  • IP, on the ground and maybe on the satellites
  • Potentially more use of existing infrastructures (APAN, I2, …) – or else it will happen anyway
  • More sites, more remote locations, much more content.
  • 100 DLCs by 2005
europe
Europe
  • Various Task Forces
  • One in streaming video
    • Which collaborates with ViDe and VidMid
    • And it’s not just about streaming
  • Interest in high-quality video-conferencing
    • ATM codecs very popular – led to ATM/IP development…
    • High resolution, high frame rate, …
    • A lot of MPEG2 developments
    • See also U.Wash/Sony collaboration on HDTV/IP
  • Lot of usage for distance education
europe1
Europe
  • VRVS
    • Very popular in Physics community
    • Came from CERN
    • Supports multicast, gateways into unicast
    • Supports various A/V codecs over rtp
    • Gateways into H.323, SIP and Access Grid (and others as they are invented…)
    • Virtual-Room based for grouping
and closing the circle
And closing the circle…
  • The World Bank is meeting with ViDe and I2 to explore options
  • Maybe connect Washington WB HQ to Abilene?
  • Europe connected to US over 2.5Gb/s link(s)
  • VRVS used as glue for various network A/V projects
