PROBLEM TO BE SOLVED: To provide the multi-standard uncompressor/compressor that is able to make uncompression and/or compression according to any of a plurality of protocols and its method. SOLUTION: A decoder 200 has a decoder module provided with a parser 36, a block decoder 50, and a motion compensation engine 86, and they are divided into functional blocks. Each functional block may be bypassed in the case that the block is not required or a compression algorithm does not need the functional block and a frame is uncompressed so as to increase a speed of the decoder. Each functional block is used again for uncompression or compression based on a different standard or with respect to different operation of the decoder such as uncompression and compensation. |
