    Abstract: A central database provides a location for creating and storing samples of known television commercials. The database of commercial samples is downloaded to a set-top box via a communicate link. The set-top box incorporates a processor for comparing a television signal with the database of known commercial messages to detect the presence of commercial messages. The set-top box may be used to control a recording unit to stop recording for the duration of the commercial message or flag the commercial message for muting or manual skipping during playback. Using this system, the user has the ability to positively detect commercial messages and eliminate the commercials from viewing if desired.

    Abstract: A method and apparatus for correlating the transmission of audio-video segments to digital signatures over a wireless or non-wireless medium to allow for real-time substitution and processing of audio and video programs. In one embodiment at least one digital signature having a correlated audio-video segment is transmitted as a digital waveform within an analog modulated signal representing the audio-video segment. The analog modulated signal is transmitted to a wireless receiver. The wireless receiver demodulates the digital waveforms while concurrently playing the correlated audio-video segment. An electronic user interface enables the wireless receiver to define conditional preferences to actively scan a plurality of channels and Internet addresses to substitute a currently playing audio-video segment with a preferred audio-video segment. In an alternative embodiment, a distributed computer network is the broadcast system transmitting digital signatures to either a wireless or non-wireless computer.

    Abstract: Hashes are short summaries or signatures of data files which can be used to identify the file. Hashing multimedia content (audio, video, images) is difficult because the hash of original content and processed (e.g. compressed) content may differ significantly. The disclosed method generates robust hashes for multimedia content, for example, audio clips. The audio clip is divided (12) into successive (preferably overlapping) frames. For each frame, the frequency spectrum is divided (15) into bands. A robust property of each band (e.g. energy) is computed (16) and represented (17) by a respective hash bit. An audio clip is thus represented by a concatenation of binary hash words, one for each frame. To identify a possibly compressed audio signal, a block of hash words derived therefrom is matched by a computer (20) with a large database (21). Such matching strategies are also disclosed. In an advantageous embodiment, the extraction process also provides information (19) as to which of the hash bits are the least reliable. Flipping these bits considerably improves the speed and performance of the matching process.

    Abstract: A detection apparatus includes a tuner tuned to the program and a meter coupled to the tuner and arranged to detect content ancillary information from the program tuned by the tuner. The content ancillary information may be a media link, closed captioning information, or the like. The meter may also be arranged to extract a broadcast signature from the program. A comparator compares the broadcast signature to a reference signature selected from a library of reference signatures based upon the content ancillary information. Broadcast signatures from unknown programs may be clustered at least partially on the basis of the content ancillary information.
