An apparatus for a synchronized playback of audio-video signals

摘要

To provide an apparatus for a synchronized playback of compressed digital data of audio-video signals 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 of the invention comprises means (32 and 33) for obtaining a reference time indicating reproduction time passage of the audio signal component from reproduced data amount of the audio signal component, and means (31 and 34) for detecting progress of the video signal component in reference to the reference time.
