MPEG-4 14496-2和H.264什么区别？

MPEG-4 Part 2, MPEG-4 Visual (formally ISO/IEC 14496-2^[1]) is a video compression technology developed by MPEG. It belongs to the MPEG-4 ISO/IEC standards. It is a discrete cosine transform compression standard, similar to previous standards such as MPEG-1 and MPEG-2. Several popular codecs including DivX, Xvid and Nero Digital implement this standard.

Note that MPEG-4 Part 10 defines a different format than MPEG-4 Part 2 and should not be confused with it. MPEG-4 Part 10 is commonly referred to as H.264 or AVC, and was jointly developed by ITU-T and MPEG.
