Abstract

A method of detecting video sequences involves creating on-the-fly candidate digital signatures uniquely characteristic of successive groups of frames in accordance with a predetermined algorithm. The candidate digital signatures are compared with at least one signature of a stored sequence created in accordance with the predetermined algorithm. A candidate is identified as corresponding to the stored sequence in the event of a positive match.
