REPRODUCTION DEVICE, REPRODUCTION METHOD, PROGRAM, AND STORAGE MEDIUM

摘要

A reproduction device includes: a reproduction unit (16) for reproducing an audio signal and a video signal stream correlated to each other; an audio buffer memory (18) which stores the audio signal reproduced by the reproduction unit (16) and from which the stored audio signal is read out; a video buffer memory (20) which stores the video signal reproduced by the reproduction unit (16) and from which the stored video signal is read out; an operation detection unit (40) for detecting an input operation of an operator concerning the read out of the audio signal or the video signal from the audio buffer memory (18) or the video buffer memory (20); and a system CPU (12) which performs control to read out one of the audio signal and the video signal from the audio buffer memory (18) or the video buffer memory (29) at a predetermined speed and order and to read out the other signal at the speed and the order based on the input operation detected by the operation detection unit (40). The system CPU (12) monitors whether the difference between the current reproduction points of the audio signal and the video signal exceeds a predetermined value.
