摘要:A compressed video decoder receives a stream of compressed video data in achannel buffer, and decompresses it. A portion of the decompressed video data isrecompressed as intraframe data to serve as an anchor frame. The intraframe data is

motion compensated, and then a reference picture is selected. The reference frame datais decompressed. Next, a region of interest is selected and stored in display memory forthe decompressed form. The recompression of data to be used as an anchor frame canbe done in a substantially lossless manner by using DCT with the same quantizationmatrix, quantizer scale, and field/frame coding type.
