Method and apparatus for synchronizing audio and video streams

摘要

Some embodiments of the invention provide a method for synchronizing an audio stream with a video stream. This method involves searching in the audio stream for audio data having values that match a distinct set of audio data values and synchronizing the audio stream with the video stream based on the search. In some embodiments, the distinct set of audio data values is defined by a predetermined distinct tone. In other embodiments, the distinct set of audio data values is defined by audio data contained in the video stream.
