DEVICE AND METHOD FOR PROCESSING DATA

摘要

PROBLEM TO BE SOLVED: To efficiently utilize the band width of a communication channel. SOLUTION: A data processor is provided with data compression decoders 10 and 22 for decoding encoded first and second kinds of encoding data and generating first and second kinds of extension data which express first and second kinds of source data to be the original for the generation of the first and second encoding data by a compression encoding algorithm, a data compression encoder 111 for compressing and encoding extension data based on the compression encoding algorithm through the use of first and/or second kinds of compression parameter data and a communication unit which is connected to the data compression decoder 22 and the data compression encoder 111 to transmit first and/or second extension data and first and/or second compression parameter data.
