摘要：
A method for transcoding between videostreams using different entropy coding, comprising the steps of (A) decoding a first videostream using a first set of entropy codes, and (B) generating a second videostream by entropy encoding the decoded first videostream 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 videostream.
