ISMA mpeg-4 multicast stream plus a unicast audio mp3 stream. At
this point, plans are to cover the special Sunday community meeting
as well as the normal Monday and Tuesday program.
Welcome
The University of Oregon
is working on many aspects of testing and developing multicast
applications. The purpose of this web page is to describe how we
are using multicast and to help other members of the Internet2
community send and receive multicast content.
The primary video codecs used at the University of Oregon to
encode the video are H.261, MPEG-1, and MPEG-2. These codecs are
implementations of standards described in the IETF RFCs. Support for different
operating systems is variable.
Windows has the best standards-based and proprietary
applications for receiving multicast content. There are
applications that can play video encoded with each of the codecs
mentioned above, and some applications can view streams encoded
with any of the standard codecs.
UNIX and MacOS have, until recently, only supported H.261
multicast streams, but Hoang Tran developed MIM to
receive MPEG-1 streams on UNIX computers. We are excited about
increasing the potential audience that can receive high quality
multicast video.
We are also working on software applications to make it easier
for the Internet community to source multicast video. The two
components that we hope to have available by summer 2000 are MIMd
and URD CGI. These components will allow those with a UNIX
workstation to stream MPEG-1 content to other people on the
Internet. MIMd will stream MPEG1 video from a file, and URD CGI
will allow those who have URD support on their last-hop routers to
launch a multicast session from a web page.
We hope you find this information useful and we appreciate any
feedback you might
send us.
