ABSTRACT:
To provide an apparatus for a synchronized playback of com- pressed digital data of audio-video signals adequately even when there are data errors with a simple configuration to be applied to a system having comparatively low data processing ability, independent of resolution of a software timer of the system, the apparatus obtains a reference time indicating production time passage of the audio signal component from reproduced data amount added with rejected error data amount of the audio signal component, and detects progress of the video signal component in reference to the reference time considering rejected error video data amount.
