I see it more like this. Though this my personal opinion and doesn't  
represent any kind of truth.

-There is political pressure to create a standard which isn't very  
dependant on western companies.
-They form a makeshift group to develop something usable. The group is  
mostly based on Chinese academics the merits of whom we have no knowledge.
-They take AVC and remove complex features and heavily patented  
technologies and try to put something in to replace those and develop  
other solutions as much as they can.

So AVS has all the features to become a messy system developed by amateurs  
etc. but if you say that it is pretty good and functionable then I won't
