Kodierung und Dekodierung von digitalen Daten |
摘要 |
<p>The present invention relates to a system for variable-length-coding and variable-length-decoding digital data (e.g. video and/or audio data) divided into block units of a predetermined size. The system, in operation, comprises the steps for variable-length-coding each block data according to various scanning patterns, accumulating the various lengths of variable-length-coded data, selecting a scanning pattern corresponding to a minimum accumulated length, transmitting the variable-length-coded data according to the selected scanning pattern and scanning the transmitted data according to the same scanning pattern as applied to the variable-length-coding process, whereby the scanned data is variable-length-decoded. As a result, data compression can be improved efficiently by means of utilizing an optimized scanning pattern for variable-length-coding and variable-length-decoding of the block data. <IMAGE></p> |
