Abstract: A media item included in a broadcast is identified by receiving, at a processing device including a processor, a first recorded representation of a first media broadcast, which includes a recording of at least a portion of a first media item, via a known media station. The first recorded representation. An identity of the first media item is determined based on a broadcast schedule associated with the known media station. A second recorded representation of a second media broadcast transmitted via an unknown media station, which includes a recording of at least a portion of a media-item-of-interest is also received at the processing device. The media-item-of-interest is identified by the processing device based on a block-by-block comparison of the first recorded representation to the second recorded representation. The comparison includes comparing first blocks included in the first recorded representation against second blocks included in the second recorded representation on a frame by frame basis.

Abstract: A system and method is provided for managing visual content. In one instance, an exemplary method includes receiving a stream of video fingerprints derived in a fingerprint generator by an irreversible data reduction process, from respective temporal regions within a particular visual content stream and at a fingerprint processor that is physically separate from the fingerprint generator via a communication network. The fingerprints are processed in the fingerprint processor to generate metadata which is not directly encoded in the fingerprints. Processing of the fingerprints includes windowing the stream of fingerprints with a time window, deriving frequencies of occurrence of particular fingerprint values or ranges of fingerprint values within each time window, determining statistical moments or entropy values of said frequencies of occurrence, comparing said statistical moments or entropy values with expected values for particular types of content, and generating metadata representing the type of the visual content.

Abstract: A method for generating a signature is disclosed. As part of the method, a first number of bits are identified in respective rows of an audio signature matrix that are determined to be the strongest bits in the row, bits of the audio signature matrix are replaced with respective cells having values depending on whether the respective bits are included in the first number of bits, a set of uniformly distributed numbers are generated within a range of numbered locations corresponding to cells of the audio signature matrix; numerical distances are determined, from respective numbers in the set of uniformly distributed numbers, to the numbered locations of the matrix, associated with nearest occurrences of a first value. A set of integers is generated based on the distances.

Abstract: Methods and apparatus to identify media content using temporal signal characteristics are disclosed. An example method includes generating a reference signature based on a reference signal corresponding to known media, generating sums based on peaks in a media signal corresponding to media, identifying signal peaks based on the generated sums, generating a second signature based on normalized curve features, wherein the normalized curve features respectively correspond to the identified signal peaks at a corresponding temporal locations of the corresponding signal peak, and determining whether the media signal corresponds to the reference signal based on a comparison of the reference signature and the second signature.

Abstract: Methods and systems for processing a sample of a media stream are provided. In one example, a method includes receiving a sample of a media stream rendered by a media rendering source, and for matching media recordings from which the sample was obtained, the method also includes receiving a signature file including a temporally mapped collection of features describing content of the matching media recordings. Each received signature file may be stored in memory. In addition, a signature stream may be received that includes features extracted from the media stream, and a number of matching features between the signature stream of the media stream and the signature file for at least one matching media recording can be determined. In one example, when substantially matching features between the signature stream of the media stream and the signature file for a matching media recording stop occurring, a discontinuity can be identified.

Abstract: A system and method for detecting one or more advertisements broadcast on a channel in real time includes a step of extracting a first set of audio fingerprints and a first set of video fingerprints. The first set of audio fingerprints and the first set of video fingerprints correspond to a media content broadcast on the channel. The method also includes a step of generating a set of digital signature values. The set of digital signature values corresponds to an extracted set of video fingerprints. The method also includes a step of detecting the one or more advertisements broadcast on the channel with the processor. The first set of video fingerprints and the audio fingerprints is extracted sequentially in the real time.
