You're on the right track,
Sneak8r but into the wrong technical tree of documents. Try to aim your searches more towards networked multimedia implementations within that time frame. The invention being questioned claims to be a new system at that time which includes the following:[list=1][*]a method of digitizing and compressing analog signals (video, voice and music are what we want, vector graphics and pure digital computer imaging is outside of this)[*]storing the results in an indexed library[*]that a remote user of the system may access to make a selection[*]that is sent to a receiver[*]that decompresses and plays it or saves it for later viewing.[/list=1]
(That's still a work in progress and should not be considered a sustitute for studying the actual claims made
within the patent(s) yourself)
Now if, for instance, you found a good, published description of how to encode a video or music file and upload it to a BBS to share with others, it might be a very good find.
