DATA COMPRESSION APPARATUS AND DATA EXPANSION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a technology of improving the compression efficiency without increasing a time required for compression processing.

SOLUTION: A data compression apparatus 13 includes: a segmentation processing section 31 for sequentially segmenting a data block corresponding to any of a plurality of prescribed data types from stream data; a plurality of data compression processing sections 33a to 33c for carrying out the data compression processing; and a distribution processing section 32 for sequentially distributing the data block segmented by the segmentation processing section 31 to any of a plurality of the data compression processing sections 33a to 33c in response to the data type of the data block.
