Abstract: An audience measurement system (10) collects data representative of tuned programs rather than of tuned channels, and includes (i) a household metering apparatus (14) which records ancillary codes or extracts program signatures from the programs if no ancillary codes are found therein, (ii) a reference apparatus (32) which monitors broadcast programs to be monitored, which extracts reference signatures therefrom, which records whatever ancillary codes may be associated with these broadcast programs and, if no ancillary codes are present, which compresses and stores a digital replica representative of the braodcast programs to be monitored, (iii) a data collection apparatus (36) which compares the household and reference data to determine (a) which of the broadcast programs to be monitored were selected for viewing and/or listening, (b) which of the metered households selected the braodcast programs to be monitored for viewing and/or listening, and (c) at which times the broadcast programs to be monitored were slected for viewing and/or listening.

Abstract: PROGRAM IDENTIFICATION METHOD AND APPARATUS A method and apparatus for identifying programs such as television programs received from various sources detects the occurrence of predetermined events such as scene changes in a video signal and extracts a signature from the video signal. The signatures and the times of occurrence of the signatures are stored and subsequently compared with reference signatures to identify the program. The signature may be compared in pairs to increase resolution, and the time interval between events or signatures may also be used to identify the program, either by themselves or in conjunction with the signatures.

Abstract: A correlation meter is disclosed for determining tuning status of a tunable receiver (38). The correlation meter receives an output of the tunable receiver, such as an acoustic audio output of the tunable receiver. An analog to digital converter (102) converts the output of the tunable receiver to a digital sample side representation. An antenna (16) or other signal collector receives reference side representations corresponding to channels to which the tunable receiver may be tuned. The correlation meter correlates the digital sample side representation and the reference side representations as the reference side represenations are received by the correlation meter in order to determine the tuning status of the tunable receiver (38).

Abstract: An image recognition system (10) and method are provided for identifying a pattern of a plurality of predetermined patterns in a video image. A plurality of feature image signatures are extracted (84) and the stored (86) corresponding to each of the plurality of predetermined patterns. A universal feature image signature is extracted (84) and is stored (88) that includes each of the stored feature image signatures. A predetermined series of portions of a captured video image (28A) is sequentially compared (100, 102) with the universal feature image signature to identify matching portions. Each of the identified matching video image portions is compared (104, 108) with the stored feature image signatures to identify the predetermined pattern.

Abstract: In a passive identification apparatus for identifying a predetermined individual member of a television viewing audience in a monitored viewing area, a video image of a monitored viewing area is captured. A template matching score is provided for an object in the video image. A Eigenface recognition score is provided for an object in the video image. These scores may be provided by comparing objects in the video image to reference files. The template matching score and the Eigenface recognition score are fused to form a composite identification record from which a viewer may be identified. Body shape matching, viewer tracking, viewer sensing, and/or historical data may be used to assist in viewer identification. The reference files may be updated as recognition scores decline.
