description A method and apparatus for synchronizing audio and video portions of a media program signal is disclosed. The method comprises the steps of detecting an audio event in the audio portion of the media program signal, measuring the timing interval from the audio event to a subsequent video synchronization pulse in the video portion of the media program signal, and storing the timing interval in a third portion of the media program signal. The apparatus comprises a voice detector for detecting an audio event in the audio portion of the media program signal, a timer for measuring the timing interval from the audio event to a subsequent video synchronization pulse in the video portion of the media program signal, and a processor for storing the timing interval in a third portion of the media program signal.
