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


Rights-L






Standards for video metadata in DC, MPEG7, RDF
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:


East Asia and Pacific:


Benin, Cote d’Ivoire, Ethiopia, Ghana,
Senegal, Tanzania, Uganda
Australia, China(2), Korea, Singapore,
Thailand, Vietnam
Europe and Central Asia:

France, Spain, Turkey, Ukraine
Where is it? (2)

Latin America and the Caribbean


Middle East and North Africa


Bolivia, Chile, Colombia, Costa Rica,
Dominican Republic, Ecuador, Nicaragua,
Peru
Egypt, Jordan
North America

Canada, Mexico, USA (2)
How is it done?



3 satellites (Asia-Pacific, Americas,
Europe-Africa)
WB Fibre links between the groundstations
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



Interest in high-quality video-conferencing





Which collaborates with ViDe and VidMid
And it’s not just about streaming
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…
