ViDe www.vide.net • Video Development Initiative • An activity of SURA to support member Universities (and beyond) • Many projects/working groups
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 • 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” • 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 • Deliver an I2-wide infrastructure/service, based on ViDe designs and experience • Large scale MCUs at OSU • Training services
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 • 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 • 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? • 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? • 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) • 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? • 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 • 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
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… • 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
Many Asian activities • I have not covered Asian activities due to lack of time, but… • MY – MCS • KR - HAT and MCONF • JP – MPEG4, MPEG2 • SG – H.323, iVCNet • AU – VoIP, H.323, SIP, HQ-Video, …
Many technologies… • Let’s talk later…
