    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.

    Abstract: System and methods for characterizing interest points within a descriptor are disclosed herein. The systems include generating a set of interest points related to an audio sample. A set of gradients relating to respective interest points in the set of interest points can be generated. A set of descriptors can then be generated based upon the set of interest points and the set of gradients and used in comparison to reference descriptors to identify the audio sample. The disclosed systems and methods provide for an audio matching system robust to pitch-shift distortion by using gradients that characterize the time-frequency neighborhood around an interest point rather than solely relying on interest points themselves. Thus, the disclosed system and methods result in more accurate audio identification.

  • Patent number: 8416648
    Abstract: Producing a servo pattern on a media involves rotating a master, and during a first revolution of the master, forming a first transition at a first radial position on the master, and forming a first transition at a second radial position. During a second revolution of the master, a second transition at the first radial position is formed, and a second transition at the second radial position is formed. By exposing individual servo burst transitions located at the first and second radial positions, in separate disk revolutions, only one of the magnetic transitions will inherit a particular deflection from a nominal radial position. If there are any mechanical disturbances, each magnetic transition will be randomly displaced from its nominal position, reducing the written-in run-out by ?n, where n is the number of magnetic transitions in a particular servo burst.

  • Patent number: 8069158
    Abstract: After a reception start request of contents is issued, the presence or absence of a PD connected to a PC is discriminated. If no PD exists, the received contents is recorded into only the PC. If the PD exists, a media type of PD is discriminated. If it is a built-in type, the received contents is recorded into the PC, also transferred to the PD, and recorded into a storing medium in the PD. If it is a media type, whether or not the storing medium has been loaded into the PD is discriminated. If it has been loaded, the received contents is recorded into the PC, also transferred to the PD, and recorded into the storing medium in the PD. If it is not loaded, the user is urged to load the storing medium. Since the recording of the received contents into the PC and the recording into the PD are automatically executed, there is no need to individually execute those processes.

  • Publication number: 20030086341
    Abstract: Copies of original sound recordings are identified by extracting features from the copy, creating a vector of those features, and comparing that vector against a database of vectors. Identification can be performed for copies of sound recordings that have been subjected to compression and other manipulation such that they are not exact replicas of the original. Computational efficiency permits many hundreds of queries to be serviced at the same time. The vectors may be less than 100 bytes, so that many millions of vectors can be stored on a portable device.

  • Publication number: 20020093883
    Abstract: The present invention pertains to a structure of pick-up head and its method for accessing signals, which operates in coordination with a disk made by ferroelectric material. An electric field is generated around the ends of two conductive wires by exerting a voltage on the wires. When the ends of the two wires are being close to the disk, the electric field polarizes the data-storing surface, which is formed by the ferroelectric material, so as to reach the function of writing. And as reading is needed, the two wires are also utilized of being induced by the electric lines of polarized area on the ferroelectric material to solve the data signals stored on the disk. Because the structure of pick-up head is simple and it is able to generate a smaller effective electric field, it is advantaged for the trend of miniaturization of pick-up head and capable of increasing the density of data on the disk.
