ABSTRACT:
An automated lip sync error corrector embeds a unique video source identifier ID into the video signal from each of a plurality of video sources. The unique video source ID may be in the form of vertical interval time code user bits or in the form of a watermark in an active video portion of the video signal. When one of the video signals is selected, the embedded unique video source ID is extracted. The extracted source ID is used to access a corresponding delay value for an adjustable audio delay device to re-time a common audio signal to the selected video signal. A look-up table may be used to correlate the unique video source ID with the corresponding delay value.
