The TCPSAT meeting was broadcast on MBONE so if you couldn't
make the meeting (and you're not satisfied with Dan Glover's
detailled minutes) (and you have access to the MBONE)
here's how to get access to the video.

Announcing Availability of the DC IETF Sessions on the IMJ
I'm ready to announce that all the sessions from the 40th IETF in DC that were transmitted on the MBone are now available on the IMJ (http://imj.gatech.edu) for on-demand playback. You can schedule programs via the WWW page and start the MBone sessions via SDR (or the WWW page with a simple plug-in). For additional information about the MBone see http://mbone.com.
Now that I've graduated and settled down somewhat in my new position at the University of California, Santa Barbara, I hope to continue research on the IMJ and to make the archival of IETF meetings a regular service. Part of this work includes encoding the sessions in real-time as they are being broadcast. This will significantly cut down on the turn around time between when the content is first broadcast and when it is available for replay.
Finally, and as usual, I've included the original IMJ e-mail announcement for those who want additional information about the IMJ.
Any suggestions for improvement are welcome.

**** Announcing the Interactive Multimedia Jukebox
At one point on the MBone list there was a discussion of what on-demand servers exist or are being developed. Well, I'd like to announce our version called the Interactive Multimedia Jukebox (IMJ).
The IMJ web page is a request and scheduling interface for the playout of content over the MBone. CONTENT IS ENCODED SO THAT IT CAN BE RECEIVED WITH THE LATEST VERSIONS OF VIC AND VAT (ANY PLATFORM).
The IMJ page is located at http://imj.gatech.edu. Information about the IMJ including general info, a postscript version of a paper about the IMJ, how-to-use information, and how it was implemented can be found at http://www.cc.gatech.edu/computing/Telecomm/IMJ/. (Recent note: the paper will be appearing in the WWW7 conference in Brisbane, Australia)
Some quick additional information about the IMJ is included below:
IMJ Audio/Video ----------------- The IMJ uses the WWW to submit requests which are then scheduled for playout on the MBone. Right now we are offering three channels: Channels 1 and 2 are being broadcast at a TTL of 127. Channel 3 is for internal testing and has a a TTL of 15. Each channel provides DVI-2 audio and 128 Kbps H.261 video. The encoding was done using Henning Schulzrinne's rtpplay and rtpdump.
Scheduling ---------- Program scheduling uses a set of criteria to decide on which channel to schedule a program. The current set of criteria are listed just below the interactive schedule. We are exploring lots of different options.
Content ------- We have been working on the jukebox paradigm with Turner Broadcasting, and as a result of their interest they have agreed to let us broadcast content on the MBone. I am particularly excited about this aspect because of their help and interest in investigating new applications on the Internet.
The plan is to add a new set of content about every two weeks. When this happens, the old content will be moved to the secondary request menu for two weeks. The old-old stuff will be removed. Hopefully I'll be able to advertise on the MBone list when the new stuff is available.
Development Platform -------------------- As is mentioned in the paper on the IMJ information page we are using the IMJ as a platform for a variety of research issues including providing interactivity, supporting multiple heterogeneous streams, video server organization, tracking usage, program scheduling, and pricing.
Acknowledgments ---------------- In addition to Turner Broadcasting, several other groups have made the IMJ possible. The GT Broadband Telecommunications Center sponsored much of the research and some of the equipment, and GT Office of Information Technology offered technical assistance and additional equipment.
Please send any feedback or suggestions to [email protected] or [email protected].
