Minutes of the Teleconferencing BOF (TELECONF)

There has been considerable discussion about using the Internet in
support of remote conferencing.  Ideas range from using the network to
provide a shared workspace, such as common document viewing and editing,
to full motion video conferencing.  The BOF in Santa Fe was intended to
bring together people that are doing current research in the area and to
see if a common direction can be found.  Several researchers presented
their work.

Steve Casner/ISI presented an overview of Multimedia Conferencing
including work that has been done on the Terrestrial Wideband Network
and DARTnet.  Paul Milazzo/BBN talked about their efforts with
workstation based video windows.  Hans Eriksson/SICS told the group
about their efforts with the MultiG - research programme which is
working toward a Collaborative Desktop and Telepresence.  Sze-Ying
Wuu/Bellcore explained the workings of their Touring Machine, as system
for the management of mixed multimedia.  Yee- Hsiang Chang/MCNC told the
group about their project to use packet video for use on the Concert
network.  Peter Kiestein/UCL provided information on the meeting on
International Multimedia Conferencing held at ISI on 13 November, 1991.

After the presentations there was discussion about the various parts of
Multimedia Conferencing and how the job of creating a working system may
be broken into manageable tasks.  It was suggested that there are four
areas of work:


  1. Shared Workspace.  This includes things like shared whiteboards,
     editors and generalized windows for viewing other applications.

  2. Conference Management.  This concerns conference setup, connection
     management and coordination for the various parts of the overall
     conference.

  3. Transport Formats.  This will define the formats of media (i.e.
     video, audio, image) and how they are to be transported over the
     network.

  4. Data Delivery.  This area needs to address the service guarantees
     needed by real-time data and to provide reliable multicast
     capabilities.


A new Working Group, chaired by Steve Casner, was create to coordinate
work being done on the transport formats of video and audio over UDP. It
was recognized that UDP does not provide the necessary service
guarantees for real-time data.  However, it was viewed that useful work

                                   1





could be done over UDP on lightly loaded networks until a better means
of data delivery is made available.

It was felt by the group that the IETF should continue work in these
areas and should be coordinated with other standards groups.
