摘要
Methods and transcoders are disclosed for video transcoding input macroblocks to an output macroblock. One of the methods estimates an output macroblock mode for the video transcoding. A spatial weight is determined based on size of overlapping areas of each of the input macroblocks with a correlation area that is correlated with the output macroblock. A discrete cosine transform (DCT) weight is determined based on a number of zero DCT coefficients of each of the input macroblocks that overlap the correlation area. The output macroblock mode is estimated based on the spatial weight and the DCT weight.
