Abstract:
Methods and apparatus to identify media content using temporal signal characteristics are disclosed. An example method to identify media content includes generating a first signature based on a media content signal, the first signature comprising a plurality of first normalized features, each normalized feature corresponding to a signal peak and located at a temporal location of the signal peak in the audio signal, correlating the first signature to a reference signature comprising second normalized features to obtain an index, and determining that the first signature represents the same media content as the reference signature when the index is greater than a threshold.
Abstract:
A computerized method for engaging a user of a mobile computer system, The mobile computer system may be connectible to a server over a wide area network. An audio signal of ambient audio is autonomously sampled in the vicinity of the mobile computer system to capture one or more audio samples of the audio signal. The multiple samples of the audio signal are autonomously sampled without requiring any interaction from the user, thus avoiding an input from the user to capture each of the samples. The audio sample may be processed to extract an audio signature of the audio sample. The audio signature may be compared with multiple previously stored reference audio signatures. Upon matching the audio signature with at least one reference audio signature a matched reference audio signature may be produced.
Abstract:
Systems, methods, devices, and computer program products provide social and interactive applications for detecting repeating content in broadcast media. In some implementations, a method includes: generating a database of audio statistics from content; generating a query from the database of audio statistics; running the query against the database of audio statistics to determine a non-identity match; if a non-identity match exists, identifying the content corresponding to the matched query as repeating content.
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:
Digital video signature apparatus and methods for use with video program identification systems are disclosed. The disclosed apparatus and methods identify a video program using a sequence of signatures. Each of the signatures includes a set of centroids corresponding to one of a plurality of frames of the video program. The apparatus and methods compare the sequence of signatures to a set of reference sequences of signatures and identify the video program based on the comparison of the sequence of signatures to the set of reference sequences of signatures.
Abstract:
Methods and apparatus to adaptively gather audience information data are disclosed. The disclosed methods and apparatus monitor system factor(s) and select one or more sensors from a plurality of sensors positioned to gather audience measurement data based on the monitored factor(s). Thus, the disclosed methods and apparatus adapt to the conditions they face by selecting an amount and/or type of audience measurement data they gather.
Abstract:
A system for identifying motion video/audio content by means of comparing a video A to a registered video B so as to determine if they are originally the same as each other, wherein said system at least comprises a fingerprint extractor A for fingerprint A from the video A; a fingerprint database for the registered video B; and a matcher which is adapted to search from the fingerprint database for the registered fingerprint B of the video B by means of comparison of fingerprint A with a shifting window of a possible fingerprint B, so as to determine that the video A is visually identical to the video B if a match is found. According to the present invention, the method for extracting a fingerprint data from video/audio signals facilitates the automatic identification, archiving and search of video content, and can be of archiving without the need for human visual inspections.
Abstract:
Methods and apparatus for media source identification and time shifted media consumption measurements are disclosed. A disclosed method identifies a time shift associated with one of a plurality of media sources local to a media delivery device by generating a library of first signature information local to the media delivery device, wherein the library of first signature information includes records, each of which contains a time stamp, a signature value and a source identifier associated with a respective one of the plurality of media sources, generating second signature information based on media presented via the media delivery device, generating a collection of matching signature information based on the first and second signature information, and performing a time shift analysis on the collection of matching signature information to identify the time shift associated with the one of the plurality of media sources local to the media delivery device.
Abstract:
Methods and apparatus for determining whether a media presentation device is in an on state or an off state are disclosed. A disclosed example method comprises determining first and second characteristics of a signature associated with a signal representative of media content presented via a media presentation device, evaluating the first and second characteristics to determine first and second fuzzy contribution values representing, respectively, degrees with which the first and second characteristics correspond to the media presentation device being in at least one of an on state or an off state, determining a third fuzzy contribution value based on a number of the first and second contribution values indicating the media presentation device is in one of the on or off states, and combining the first, second and third fuzzy contribution values for use in determining whether the media presentation device is in the on state or the off state.
Abstract:
A method and a device (1) are provided for interacting with events in a broadcast audio stream. Patterns in the audio stream are compared to a stored signature (29) associated with the events and a function is executed in response to a successful match indicating the detection of an event. A viewer can participate in a broadcast quiz show using the device (1). Questions are provided in a graphical representation on the display (15) of the device (1) and the user can input answers to the questions. The event may be a buzzer in the audio stream of the broadcast quiz show, indicating that the time for responding to a question has expired and the function executed in response to detecting the signature of the buzzer may include terminating a time period in which the user can answer the questions using the device. The method of the invention also includes connecting to a server (3) for downloading data and instructions for participating in the interactive services and uploading user inputs for receiving rewards and prizes.
