发明名称 Audio/video synchronous reproducer enabling accurate synchronization between audio and video data and a method of audio/video synchronous reproduction
摘要 In an audio/video synchronous reproducer for carrying out audio reproduction and video display synchronously in response to audio data and video data, an audio processing section (6) processes the audio data to produce a processed audio data amount in addition to an audio reproduction control signal. Based on the processed audio data amount, an audio time stamp deriving section (52) derives an audio time stamp equivalent value. Comparing the audio time stamp equivalent value with a video time stamp produced in a video processing section (3), a time stamp comparing section (53) produces a comparison result signal indicative of a delayed/advanced relationship between the video data and the audio data. In response to the comparison result signal, a video control arrangement (54,55) controls the operation of the video processing section. <IMAGE>
