摘要： An apparatus to decode an encoded bit stream obtained by dividing the moving image into a plurality of rectangular regions includes a rectangular region size determination unit for determining a variable size of the regions in a sequence (a set of continuous frames) based on region size information multiplexed in the encoded bit stream. The apparatus includes a decoding unit for decoding coding mode information multiplexed in the encoded bit stream for each of the regions, and a decoding unit. The coding mode information includes (1) prediction type information selected from information indicating either inter or intra prediction coding, and (2) intra prediction block size information indicating a size of a unit region for the intra prediction coding indicated by the prediction type information.

摘要： A loop filter unit 11 carries out a class classification of a local decoded image generated by an adding unit 9 into one class for each coding block having a largest size determined by an encoding controlling unit 2 and also designs a filter that compensates for a distortion piggybacked for each local decoded image belonging to each class, and also carries out a filtering process on the above-mentioned local decoded image by using the filter. A variable length encoding unit 13 encodes, as filter parameters, the filter designed by the loop filter unit 11 and used for the local decoded image belonging to each class, and a class number of each largest coding block.
