摘要：A system for variable-length-coding and variable-length-decoding digital data divided into a block unit of a predetermined size which includes 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 variable-length-coding process, thereby the scanned data being 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.
