Abstract

PURPOSE:To execute efficient compression to the data of high randomization by executing numeric value-conversion to the set of data in which the absolute value of a numeric value is small and after that, executing data compression. CONSTITUTION:In data compressing part 1, a processing is executed to divide a serial data string by a block constituting part 10 for the unit of blocks. On the other hand, difference between correlative data, which is selected and outputted from a correlative data storing part 13 to store the correlative data for one block, and data to execute compression for one block is operated in a differential arithmetic part 11. Based on this result, a correlative data determining part 12 selects the correlative data to be the most efficient to execute the data compression from the correlative data storing part 13 and a differential data compressing part 14 executes the compression of data to be the difference. A correlative data identifying code prepared in the correlative data storing part 13 and compressing data prepared in the differential data compressing part 14 are synthesized to frame data in a frame constituting part 15. Thus, the efficient data compression can be executed to the data of the high randomization.
