Video compression algorithms

JAVA Applet implementation of MPEG-1 decoder (Don't bother unless your browser is JAVA enabled.)
A demonstration and brief discussion of the MPEG-1 video compression scheme, with particular emphasis on the ramifications for an implementation of a JAVA MPEG-1 decoder. Has links to downloadable JAVA source.
As the author indicates, the JAVA implementation is slow; not to play, but in decoding the MPEG-1 bitstream. For a 15 frame sequence, it takes on the order of 20 seconds to decode. It's hard to tell if the sequence is then played at the correct speed because it's a synthetic sequence.

Summary

Interesting and informative discussion.

The player itself is too slow.

Could provide the basis for further work.

Shows what can be done using JAVA (and perhaps what shouldn't be)
