Abstract: Presented herein are a system, method, and apparatus for audio and video synchronization. In one embodiment, there is presented a method for displaying audio data and video data. The method comprises examining a plurality of portions of the audio data, where each of said plurality of portions of audio data is associated with a time stamp; examining a plurality of portions of the video data, where each of said plurality of portions of the video data is associated with a time stamp; decoding one of the portions of the video data; and decoding one of the portions of the audio data while decoding the one of the portions of the video data. The difference between the time stamp associated with the one of the portions of the video data and the time stamp associated with the one of the portions of the audio data is within a certain margin of error from a predetermined offset.
