  • Patent number: 6058141
    Abstract: A method and apparatus wherein raw video and audio are captured and digitized and stored at a frame rate different from the playback stand frame rate. The audio and the video are separated, the video as a frame and the audio as a data stream wherein there are time links to the video frame. The playback entails multiplexing the video and the audio, and where the multiplexer is operating at the standard frame rate synchronization is not maintained. The present invention discloses modifications of the audio header and/or data to accommodate the differences in the multiplexing frame rate and the original capture frame rate. If the originating frame rate is one half the standard then the audio header information is changed to indicate that twice as much audio information exists, whereupon the multiplexer will take the video frames and properly multiplex the proper and therefore synchronized audio data.
