A reduced memory MPEG video decoder

This paper proposes a decoding system that reducers memory usage requirement by ten fold when decoding MPEG bitstreams. The system stores the anchor frames used in reconstructing, the P- and B- frames in compressed format, thereby allowing memory to be embedded within the decoder chip. A pseudo decoding, circuitry is used to extract relevant encoding parameters, a data analyzer is used to compute statistics and a pair of encoder and decoder is used to store decoded pixel data to memory buffer anchor frames and to convert encoded pixel data to suitable format for reconstructing-pictures in MPEG decoder.
