  • Publication number: 20180318711
    Abstract: Example methods and systems for computing a reaction time from an indexed event occurring in an indexed recording to a reaction signal are described. An example method includes receiving a sample of ambient content of a computing device, determining a position identification of the sample of ambient content into an indexed recording to which the sample of ambient content matches, based on the position identification, synchronizing display of content on a user interface of the computing device to the indexed recording, and computing the reaction time. The reaction signal is generated by the computing device and is indicative of a user's response to the indexed event.

The data receiver receives parameters configured and managed from each of small cells. The data processor is configured to pre-process the received parameters to remove the unnecessary parameters and to calculate at least one performance result based on the pre-processed parameters. The data processor is further configured to establish a model based on at least one of the pre-processed parameters. The data processor determines the optimized parameter based on the best performance result of the model to determine a decision result. The data configurator is connected to the data processor and configures and manages the small cells based on the decision result.

  • Patent number: 10091745
    Abstract: Facilitation of a network assisted device-decided system can increase throughput of D2D devices and the link reliability of macrocells. In a network assisted device-decided system a macrocell can broadcast resource allocation data to D2D devices. The D2D devices can then select channels and adjust transmission power to offload traffic from the macrocell, thus creating a high spectrum efficiency with low power.

  • Patent number: 10003664
    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.

  • Publication number: 20180101610
    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.

  • Patent number: 9899030
    Abstract: A method for recognizing an audio sample locates an audio file that matches the sample from a database indexing original recordings. Each indexed 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, and the fingerprints are invariant with respect to time stretching of the sample. 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: 20160328473
    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.
