  • Publication number: 20160156731
    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.

  • Patent number: 9251796
    Abstract: Systems and methods of synchronizing media are provided. A client device may be used to capture a sample of a media stream being rendered by a media rendering source. The client device sends the sample to a position identification module to determine a time offset indicating a position in the media stream corresponding to the sampling time of the sample, and optionally a timescale ratio indicating a speed at which the media stream is being rendered by the media rendering source based on a reference speed of the media stream. The client device calculates a real-time offset using a present time, a timestamp of the media sample, the time offset, and optionally the timescale ratio. The client device then renders a second media stream at a position corresponding to the real-time offset to be in synchrony to the media stream being rendered by the media rendering source.

  • Patent number: 9225444
    Abstract: A user (102) hears an audio program being broadcast and can record a sample of the audio. The sample is then conveyed to an analyzing means (106) to determine to which broadcast station the user is listening. The analyzing means monitors many broadcast channels. Thus, characteristics of the audio sample and samples taken from the broadcast channels can be compared to find a match. Broadcast information pertaining to the broadcast channel from which the match was found may then be reported back to the user, combined with an advertisement of a promotion, prize notification, discount offers, and other information specific for a certain radio station for example.

  • Publication number: 20150205865
    Abstract: A method and system of performing high-throughput identifications of broadcast content is provided. A device can send a content identification query, which includes a sample of content being broadcast, to a server to request an identity of the content. The server will perform a computational identification of the content, return the result to the device, and store the result. For all subsequently received content identification queries requesting an identity of content being broadcast from the same source and in a time during which the content is still being broadcast from the source, the server will send the stored content identification in response to the subsequent queries. If a subsequent content identification query does not request the identity of content being broadcast from the same source or is not received during the time that the content is still being broadcast, the server will perform a computational identification of a content sample.

  • Publication number: 20140316787
    Abstract: A method for recognizing an audio sample locates an audio file that closely matches the audio sample from a database indexing a large set of original recordings. Each indexed audio file is represented in the database index by a set of landmark timepoints and associated fingerprints. Landmarks occur at reproducible locations within the file, while fingerprints represent features of the signal at or near the landmark timepoints. To perform recognition, landmarks and fingerprints are computed for the unknown sample and used to retrieve matching fingerprints from the database. For each file containing matching fingerprints, the landmarks are compared with landmarks of the sample at which the same fingerprints were computed. If a large number of corresponding landmarks are linearly related, i.e., if equivalent fingerprints of the sample and retrieved file have the same time evolution, then the file is identified with the sample.

  • Publication number: 20140214190
    Abstract: A method and system for content sampling and identification is presented. A data stream is recorded, and samples of the stream are identified. Samples can be initially taken at random for identification. Once a sample is identified and segmented within the data stream, the next time to sample may be calculated to be outside the time frame of the identified sample. Thus, the sampling period can be adaptively adjusted to be at times after identified tracks.
