ABSTRACT:
Signatures are produced for characterizing an interval of a video signal representing a picture for use in broadcast segment recognition. The signature is produced based on portions of the video signal representing corresponding regions of the picture each spaced by a certain amount from a nominal edge of the picture. A shift in the video signal corresponding with a shift in the edge of the picture from a nominal edge of the picture is detected. The portions of the video signal are adjusted to compensate for the shift in the edge of the picture and a signature is produced based on the adjusted portions of the video signal.
