Excellent point Bill.
Personally, I have not seen much in the MPEG-2 patent pool that is 
all that revolutionary. The majority of the significant IP is related 
to the coding of interlace, which is something that we would all be 
better of without. Most of the rest is incremental improvements in 
motion compensated prediction, created in large measure to 
re-establish IP developed in the '70s and early '80s that would soon 
enter the public domain. This looks like an effort to entrench the 
interests of the18 companies that made a massive investment in the 
MPEG-2 process, and have since used that standard to proliferate an 
SDTV paradigm around the world that protects their investments in 
interlace and "601."
