This site is a little old, but relevant:
http://www.siggraph.org/education/materials/HyperGraph/video/codecs/Default.htm

(may also be a factor in where the "central" in vBlog Central came from)

This PDF is an excellent overview of the whole process, but also a little out-of-date:

Ben Waggoner is a recognized expert who writes books and articles on compression/codecs. I think he may have written the above PDF when he was at Terran Interactive, the creators of (Media) Cleaner. His site, which lists his current books, is here:
