    Abstract: Methods and apparatus for characterizing media are described. In one example, a method of characterizing media includes capturing a block of audio; converting at least a portion of the block of audio into a frequency domain representation; dividing the frequency domain representation into a plurality of bands; determining a characteristic difference of a first band of the plurality of bands based on a comparison of a characteristic of the first band and a characteristic of a second band different from the first band, wherein the characteristic of the first band occurs at a time that is different than a time at which the characteristic of the second band takes place; and determining a signature bit based on a characteristic difference. Other examples are shown and described.

    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.

    Abstract: Methods, apparatus, and articles of manufacture for using location information to manage spillover in an audience monitoring system are disclosed. In particular, the example methods, apparatus, and articles of manufacture detect spillover to generate media monitoring information. Initially, a first sensor located in a first location and a second sensor located in a second location receive a portable metering device signal. First location information is associated with receiving the portable metering device signal via the first sensor and second location information is associated with receiving the portable metering device signal via the second sensor. Media monitoring information is generated based on one of the first location information or the second location information.

    Abstract: The method and apparatus operates in a video recorder and playback unit to identify selected broadcast segments, such as commercial advertisements, of a television signal in real-time for the purpose of either suspending recording or advancing playback of the television signal during each unwanted segment. A signature pattern associated with each segment of the television signal is detected and compared to stored signature patterns representative of selected segments such as commercial advertisement segments. If the signature pattern matches one of the stored signature patterns, the segment is thereby immediately identified as being one of the selected segments and is processed in real-time to control operation of the video recorder/player. If the signature pattern of the segment does not match any of the stored signature patterns, the segment is analyzed to determine whether the segment is nevertheless a selected segment and, if so, its signature pattern is stored along with the stored signature patterns.
