Abstract:
A method for transcoding between video streams using different entropy coding, comprising the steps of (A) decoding a first video stream using a first set of entropy codes, and (B) generating a second video stream by entropy encoding the decoded first video stream using a second set of entropy codes. The first set of entropy codes and the second set of entropy codes are configured to represent all valid coefficient values of the first video stream.
