ABSTRACT:
In methods for compressing data, when differences between two adjacent data among a series of N data, where N is a positive integer, are all less than a reference value, delta data values are generated on the basis of the differences. When the differences are the reference value or less and at least one delta data is stored, a command indicating that compression operations are performed on the basis of the differences, the number of the stored delta data, and the stored delta data are generated as compressed data. The compression method of the present method can obtain higher compression efficiency as compared with conventional RLC or modified-RLC compression methods.
