METHOD AND APPARATUS FOR TRANSCODING BETWEEN HYBRID VIDEO CODEC BITSTREAMS

摘要

A method and apparatus (fig. 1) performing transcoding between bitstreams coded by hybrid video codecs which uses fewer resources than decoding/decompressing the original bitstream (4 of fig. 2) and recoding/recompressing it to the second format (6, 7, 8 of fig. 2). According to a specific embodiment, the method can exploits the similarity of the standard video compression algorithms to, where possible, convert encoded parameters in the incoming bitstreams directly into encoded parameters which constitute compliant data for the outgoing bitstream.
