ABSTRACT:
In a picture encoding and/or decoding system, fast motion region blocks and slow motion region blocks are repeated by a classifying unit on the basis of motion vector to thereby be able to adaptively change. A majority decision is made as to the predetermined block with the surrounding blocks an isolated block of which is replaced by the surrounding block to thereby be able to enhance picture quality. Data of border portions of adjacent channels divided is overlapped on a border portion of each channel to thereby be able to avoid transmission of unnecessary amount of information.
