<P>PROBLEM TO BE SOLVED: To solve the problem wherein the hardware scale and the software scale become too large, when applying compression processings and scramble processings to data. <P>SOLUTION: In this data-compressing method for using a dynamic dictionary for generating a symbol, corresponding to data and registering the symbol to apply compression processing to inputted data, a symbol-generating part 101 generates a symbol from an inputted data; a dynamic dictionary part 102 registers the symbol generated, a scramble processing part 103 converts unregistered data, which is not registered in the dynamic dictionary 102 among the inputted data, the unconverted; and unregistered data are replaced with the converted unregistered data, and scramble processing is applied to the converted unregistered data . <P>COPYRIGHT: (C)2005,JPO&NCIPI |
