摘要： A method and apparatus are provided for implementing an enhanced reduced memory mode (RMM) of decoding HDTV MPEG-2 video stream. In one instance, the RMM mode is adaptively enabled with up/down conversion by using the picture-type information. In another instance, the RMM mode is provided by performing anchor-frame compression/decompression by using adaptive DPCM technique with picture-type information. The quantization (PCM) tables are generated using the Lloyd algorithm. Further, the predictor for each pixel is determined by a use of the Graham rule.

摘要： A system, method, and apparatus for reducing the video decoder processing requirements are presented herein. During a rewind operation, a reference picture for a group of pictures is decoded and stored into a reference frame buffer. By storing a reference picture for the group, the reference picture need not be decoded to display each picture in the group during the rewind operation.
