摘要： PCM data with time information is read out by an ATAPI controller 4. PCM data with time information is read out from the ATAPI controller 4 into an AV decoder 11 while ascertaining coincidence between the amount of transmitted data and that of received data. The time information is output in synchronization with the PCM data. Therefore, PCM data and time information can be easily synchronized with each other, and a dedicated line for PCM data can be omitted.

摘要： Synchronization problems between audio and video information may be reduced by determining whether a certain predetermined time has elapsed since the previous frame of video has been displayed. Thus, for example, where the audio presentation time stamp and video presentation time stamp are offset so that audio information may be presented before video information, the next video frame in the queue may be displayed immediately after the passage of a predetermined time. Then, audio/video synchronization may be achieved after passage of an amount of time determined by the setting of the predetermined elapsed time between frames. The longer the predetermined time between frames, the more slowly the video frames are displayed, but the faster audio and video synchronization is achieved.
摘要翻译： 音频和视频信息之间的同步问题可以通过确定自从先前的视频帧已被显示以来是否已经过去了某个预定时间，可以减少。 因此，例如，在音频呈现时间戳和视频呈现时间戳偏移的情况下，可以在视频信息之前呈现音频信息，可以在经过预定时间后立即显示队列中的下一个视频帧。 然后，在经过由帧之间的预定经过时间的设置确定的时间量之后，可以实现音频/视频同步。 帧之间的预定时间越长，视频帧的显示越慢，但是实现了更快的音频和视频同步。
