%X A transcoding scheme for MPEG-2 to H.264 was provided. This scheme was composed of two parts: intra prediction and inter prediction. For the intra prediction part, 8×8 block DCT-HT transform-domain converse was used, and then intra mode decision was done in HT domain to obtain the optimum mode, so that good intra prediction was acquired. For the inter prediction part, Motion Vector (MV) got from Variable Length Decoding (VLD) in MPEG-2 stream was reused as Prediction Motion Vector (PMV) of H.264, then motion prediction mode and search region were reset, so that better prediction result was acquired. Experimental results show that this scheme is feasible.
