Method for coding and decoding a data stream

摘要

The MPEG encoder with image stores for resorting and motion compensation incorporates a storage minimisation block (12). The data stream (4) from a predictor (130 is computed and quantised (Q) for Huffman encoding (14) and storage in a memory (15). A Huffman decoder (16) and another predictor (17) are provided for the read out. A compression factor of 2 can be used without significant detriment to image quality. All reformatting is done in one step by direct addressing of block rows on readout. <IMAGE>
