Abstract:
1. An apparatus for identifying video content, the apparatus comprising: a scene change detector to detect scene changes to thereby identify a plurality of repeatably detectable scenes; a scene signature generator configured to generate a plurality of scene signatures, one for each of the plurality of scenes, each scene signature being made up of concatenated pixel data extracted from a selection of repeatably identifiable pixels selected from a repeatably selected frame of the video content, where each selection of pixels represents a subset of less than all pixels in the frame from which the pixels are selected, and where the pixel data includes a truncated segment of pixel data; an input to receive the plurality of scene signatures; a comparator that determines an identification of the video content by matching the plurality of scene signatures to a database having a plurality of video content items, the database including previously determined scene signatures made up of data extracted from the selection of repeatably selected frames of the video content in the database, and an output port to provide the identification of the video content from the comparator; wherein the repeatably selected frames are predetermined frames following scene changes, and each of the frames has the same temporal position after the occurrence of its related scene change.
