Abstract
The audio-video synchronous playback apparatus of the present invention for expanding digital compressed audio data and digital compressed video data, respectively, and for synchronously playing back expanded audio data and expanded video data, comprises: an element for obtaining an audio playback time based on the amount of the played-back audio data; a means for determining progress in expanding the video data based on the audio playback time; and a recovery element for saving the processing time for the audio data and assigning a saved time to a process for the video data so as to recover any delay in a video portion when the expansion process for the video data is delayed with respect to the expansion process for the audio data.
