There has been a case where during the changing of a speed such that the continuation time is reduced or extended, the output timing of a video signal and the output timing of an audio signal can largely deviate from each other in comparison with the case of normal reproduction, and that the synchronization can not be maintained. An audio video reproduction apparatus comprising: an audio speed conversion circuit 1008 of performing audio speed conversion on a generated audio signal in such a manner that the information on an A-PTS is maintained, depending on an executing reproduction speed; an audio output buffer circuit 1009 of accumulating the audio signal having undergone the audio speed conversion and of outputting the signal according to the executing reproduction speed; a video output buffer circuit 1004 of accumulating and outputting a generated video signal; and a comparison circuit 1011 of comparing the A-PTS with a V-PTS by using the maintained information on the A-PTS; wherein using the result of the comparison, the video output buffer circuit 1004 outputs the accumulated video signal according to the executing reproduction speed.
