摘要：
An audio/video synchronous playback device includes a first synchronization section for repeating or skipping a first video data sequence in units of a video frame interval thereof to synchronize the first video data sequence with an audio data sequence, and a second synchronization section for repeating or skipping a second video data sequence in units of a video frame or video field interval thereof to synchronize the second video data sequence with the audio data sequence. A first video data sequence output and a second video data sequence output having different frame frequencies are separately synchronized with one channel of audio data sequence output with their respective precisions.
