China Netcom has been field trialling the Chinese version of H.264/AAC Video/Audio compression codec on IPTV for half year, the success of the China “home made” AVS (Audio Video Standard) codec in the trial will result in the mass deployment of AVS codec as a compulsory IPTV standard in green field deployment and also to replace the existing system which are using MPEG2/4 and H.264 standard.

It looks like the national implementation of AVS codec is more a commercial reason (not need to pay loyalty/license fee for using overseas patents) than technology superiority.
