ABSTRACT:
Synchronization of MPEG audio and video presentations is attained by detecting a lack of synchrony between the data presentations and modifying the audio data stream based on the detected lack of synchrony. Synchrony of the MPEG audio and video presentations is monitored by tracking the amount of data transferred to audio and video interfaces over time. Synchronization of MPEG audio and video presentations is achieved in a system in which audio and video interfaces are controlled by separate and independent timing signal generators by tracking the amount of audio and video data output by the respective audio and video interfaces. The amount of audio and video data output by the interfaces is compared and, as a result of the comparison, the audio data stream is modified to restore synchrony. Alternatively, presentation of the video data stream is modified to achieve synchrony.
