    摘要: A semiconductor for decoding coded image and audio data, which includes an audio processor that decodes coded audio data, and an image decoder that decodes image data. The image decoder removes coding distortion in pixels of two adjacent transform blocks which are motion-compensated, having a coded motion compensation error equal to zero, and are located inside a same macroblock. The image decoder includes a motion compensation block boundary detector that determines whether the motion compensation error of the two adjacent transform blocks located inside the macroblock is zero, and determines whether a boundary of two adjacent transform block is also a boundary of two adjacent motion-compensation blocks. The image decoder also includes a filter that removes coding distortion in pixels of the two adjacent transform blocks, and a selector that selects whether or not the filter removes the coding distortion based on the determination of the motion compensation block boundary detector.
