Method and apparatus for signaling and decoding AVS1-P2 bitstreams of different versions

A system, comprising:

• one or more processors operable to:
• when decoding version information is detected within a sequence user data field of an Audio Video Coding Standard of China (AVS) bitstream;
• decode said AVS bitstream based at least in part on said decoding version information, said decoding version information indicating one of a plurality of different AVS versions, wherein said decoding version information was inserted in said AVS bitstream during coding of said AVS bitstream;
• and
• when said decoding version information is not detected within said sequence user data field of said AVS bitstream;
• decode said AVS bitstream based at least in part on default decoding version information.

A system, comprising:

• means for detecting decoding version information within a sequence user data field of an Audio Video Coding Standard of China (AVS) bitstream, said decoding version information indicating one of a plurality of different AVS versions, wherein said decoding version information was inserted in said AVS bitstream during coding of said AVS bitstream;
• means for decoding said AVS bitstream based at least in part on said decoding version information when said decoding version information is detected;
• and
• means for decoding said AVS bitstream based at least in part on default decoding version information when said decoding version information is not detected.
