摘要
A fast reverse motion estimation algorithm with smart mode decision for H.264 reverse transcoding is proposed. The best mode for the backward transcoded macroblock is obtained by analysing the motion vectors and modes decoded from the forward bitstream. A significant reduction in the transcoding complexity with negligible impact on rate-distortion performance has been achieved.
