To output audio even if video is frozen and to synchronize video with audio immediately after a release from freeze, in an MPEG decoder or the like. Freeze of motion picture data and continuous output of it are performed using a third output buffer area 8D in a memory 8. I- and P-pictures in a data stream of motion pictures to be inputted in a freeze are decoded using a first output buffer area 8B and a second output buffer area 8C. Besides, a data stream of audio is decoded while keeping a synchronous relationship with motion pictures. Since the decoded I- and P-pictures are stored in the first output buffer area 8B and the second output buffer area 8C even in the freeze, the video data can be outputted synchronizing with the audio data immediately after a release from freeze. <IMAGE> |
