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.

Abstract: A method of processing a video stream, involves contemporaneously selecting first and second pairs of frames in the video stream with a predetermined period . The second pairs of frames have a longer period than the first pair. For each of the first and second pairs of frames, there is determined a difference value representing the number of pixels whose value has changed between the first and second frames of the pair. A particular logic level is generated depending on whether this difference value e xceeds a predetermined threshold. The generated logic levels are then compared with a dec ision map to identify cuts in the video stream
