A paper by Michael W. Marcellin, Michael J. Gormish, Ali Bilgin, Martin P. Boliek that was published in the 2000 Proceedings of the DCC. Good information of only moderate complexity in an academic format.

A presentation by Michael J. Gormish & Michael W. Marcellin, which was given at the DCC in 2000. Lots of information and figures, but as always, the slides without the talk leaves one wanting more.

RFC 2429 - RTP Payload Format for H.263+ Video Streams
The second generation fo H.263 is working on supplanting the original. Naturally, we need a standard for sending H.263v2 packets over RTP streams.

RFC 2190 - RTP Payload Format for H.263 Video Streams
The IETF standard for delivering H.263 in RTP packet streams.

This is the home page for the IETF group that reviews RTP packetization standards. Links on this page for all the drafts you can imagine for sending video and audio over RTP streams.
http://www.ietf.org/html.charters/avt-charter.htmlWikipedia entry: H.263
This Wikipedia entry describes the H.263 video compression standard. A short entry but it has a few valuable outside links.
http://en.wikipedia.org/wiki/H.263Wikipedia entry: MPEG-4
This Wikipedia entry describes the MPEG-4 standard, the version of MPEG designed for lower bit-rate applications. Light on detail.
http://www.wikipedia.com/wiki.phtml?title=MPEG-4Wikipedia entry: MPEG-2
This Wikipedia entry describes the MPEG-2 standard, the version of MPEG used to encode movies on DVD. Not too much information here, although it does enumerate the standards documents that collectively define MPEG-2.
http://en.wikipedia.org/wiki/MPEG-2Wikipedia entry: MPEG-1
This Wikipedia entry describes the MPEG-1 standard. Very sparse.
http://en.wikipedia.org/wiki/MPEG-1Wikipedia entry: Vorbis
This Wikipedia entry describes the Vorbis codec, used in the open music codec Ogg Vorbis. Overview, a few interesting links, not much detail.
