摘要：

MPEG-4 is leading the compression of multimedia application into the fruitful future for it's affluent functions to support universal access and high performance compression(2). But two excellent standard-compliant streams, MPEG-2 and MPEG-4 video, will be coexisting in different systems for a long time. This paper addresses the problems of transcoding MPEG-2 video to MPEG-4 compliant bitstream in compression domain to meet low complexity and low latency rea time application. The key issue about macroblock coding mode mismatch in transcoding processing will be discussed in detail. The reported simulation results authenticate the performance of the proposed transcoding algorithm in both objective and subjective quality.
