I believe PacketVideo's compression techniques are proprietary? Not sure who has the lions share on MPEG-4.

This is getting off-topic some (though certainly worth
discussing), MPEG-4 is based on Apples Quicktime

and since it is open, has spawned different flavors due to Apple freely liscensing through the Darwin Streaming Server program:

Any particular iteration may be proprietary, but no proprietary iteration will be accepted as the standard,
atleast in a royalty-paying sense, by MPEG. That's the whole point of it. To keep it open.

Qualcomm is basically saying that their system is much better than MPEG-4 (which is an OPEN, NON-PROPRIETARY standard), and is lining up (or trying to) the movie industry behind them. They (the Studios) don't care which flavor of codec is used, only that it is the best available, and that the savings can be realised. Both Qualcomm and Cisco are working on PROPRIETARY, OPEN codec's that each HOPE will be accepted by the movie industry for Digital Cinema, with Qualcomm planning on satellite and DVD delivery while Cisco plans to use Virtual-Private-Networks (VPN's) through Qwest.

More later.
