Abstract
The disclosure relates to an apparatus and method for creating digital signatures from frames of selected video segments such as TV commercials by a digitizing, compression and selection process which produces a multi-digit signature from each frame. The signatures are stored in a memory database. In the recognition mode broadcast video transmissions are similarly digitized frame by frame to generate signatures which are then compared with the signatures in the database to find matches. The system cycles efficiently through the database testing for signature matches and then totalizing the signature matches to determine occurrences of a match between a transmitted segment or commercial and a stored segment or commercial. The system also includes signature generating and comparison circuits which permit wide variations in the quality of the input video signals form a variety of different media sources such as off-air, videotape or camera inputs while maintaining accurate recognition.
