Patent number: 8086171Abstract: 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.Type: GrantFiled: December 22, 2010Date of Patent: December 27, 2011Assignee: Shazam Entertainment Ltd.Inventors: Avery Li Chun Wang, Chee Wong, Jonathan Symons

Publication number: 20110276333Abstract: 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.Type: ApplicationFiled: May 4, 2011Publication date: November 10, 2011Inventors: Avery Li-Chun Wang, Rahul Powar, William Michael Mills, Christopher Jacques Penrose Barton, Philip Georges Inghelbrecht, Dheeraj Shankar Mukherjee

Publication number: 20110071838Abstract: A method for recognizing an audio sample locates an audio file that most 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.Type: ApplicationFiled: November 24, 2010Publication date: March 24, 2011Inventors: Avery Li-Chun Wang, Julius O.

Patent number: 7627477Abstract: The present invention provides an innovative technique for rapidly and accurately determining whether two audio samples match, as well as being immune to various kinds of transformations, such as playback speed variation. The relationship between the two audio samples is characterized by first matching certain fingerprint objects derived from the respective samples. A set (230) of fingerprint objects (231,232), each occurring at a particular location (242), is generated for each audio sample (210). Each location (242) is determined in dependence upon the content of the respective audio sample (210) and each fingerprint object (232) characterizes one or more local features (222) at or near the respective particular location (242). A relative value is next determined for each pair of matched fingerprint objects. A histogram of the relative values is then generated. If a statistically significant peak is found, the two audio samples can be characterized as substantially matching.Type: GrantFiled: October 21, 2004Date of Patent: December 1, 2009Assignee: Landmark Digital Services, LLCInventors: Avery Li-Chun Wang, Daniel Culbert

Publication number: 20080154401Abstract: A method and system for content sampling (106) and identification is presented. A data stream is recorded, and samples of the stream are identified. Samples (106) can be initially taken at random for identification. Once a sample (106) is identified and segmented within the data stream, the next time to sample (106) may be calculated to be outside the time frame of the identified sample (106). Thus, the sampling period can be adaptively adjusted to be at times after identified tracks.Type: ApplicationFiled: April 19, 2005Publication date: June 26, 2008Applicant: Landmark Digital Services LLCInventor: Avery Li-Chun Wang
