摘要：

To balance the rate-distortion (R-D) performance and the computational cost of the MPEG-2 to H.264 transcoder, we propose a new intelligent algorithm to select macroblock (MB) mode and decide the search window size based on the energy of MPEG-2 residual MB. The proposed method remarkably reduces the transcoding complexity, and achieves similar coding gain compared to the MPEG-2 to H.264 transcoder using exhaustively full search method to determine the best block size mode. The high complexity reduction at very small rate losses makes the proposed algorithm is helpful in real-time implementation of the MPEG-2 to H.264 video transcoder.
