  • Patent number: 10383021
    Abstract: Systems and methods of handling satellite channel and LTE coexistence are provided. A first device can identify at least one first frequency band. The first device can determine that at least one second frequency band of a plurality of second frequency bands overlaps with the at least one first frequency band. In response to determining that the at least one second frequency band overlaps with the at least one first frequency band, the first device transmits a message including an identifier of the first device and an indication of the at least one second frequency band to a second device. The second device receives the message. The second device, in response to receiving a channel request from the first device, allocates, from the plurality of second frequency bands, a second frequency band different from the at least one second frequency band.

  • Patent number: 9591376
    Abstract: Synchronizing signals in a communication system may include determining the amount of data stored in a buffer, comparing the amount of data to a plurality of threshold levels and adjusting a speed of a clock used for decoding the data based on the comparing. The signals to be synchronized may correspond to a decoder clock in a set top box and to an encoder clock in a head end. The data in the buffer may correspond to packets of data corresponding to compressed audio and video information. The process may also include decoding information based on the clock and slew limited limiting the clock may. The process may further include setting at least one threshold to a calibration threshold during a calibration mode and a post-calibration threshold during a post-calibration.

  • Patent number: 9344725
    Abstract: Error concealment for motion picture expert group (MPEG) decoding with personal video recording functionality. Error concealment of MPEG data may take place within various components within playback, recording, reading and writing data systems. The error concealment may be provided within existing systems whose components may not be capable of accommodating errors within MPEG data. In certain embodiments, the available data that contain no errors is maximized to conceal those portions of the data that do include errors.

  • Patent number: 7724307
    Abstract: Aspects of noise reduction in digital video may comprise monitoring at least one of memory usage and memory bandwidth usage of memory utilized to process video data. The aspect may further comprise adaptively adjusting filtering of the video data according to the monitoring. At least one of impulse filtering, temporal filtering, and spatial filtering may be utilized for the filtering of the video data. At least one of the impulse filtering, the temporal filtering, and the spatial filtering may be adaptively adjusted based on the monitoring. Furthermore, at least one of motion information and edge information may be estimated from the video data for utilizing in at least one of the impulse filtering, the temporal filtering, and the spatial filtering. At least one of the estimated motion information and the estimated edge information may be adaptively adjusted based on the monitoring.

  • Patent number: 7508874
    Abstract: Error concealment for motion picture expert group (MPEG) decoding with personal video recording functionality. The present invention is operable to perform error concealment of MPEG data within various components within playback, recording, reading and writing data systems. The present invention is operable within existing systems whose components may not be capable of accommodating errors within MPEG data. Whereas prior art systems typically cannot deal with any corruption without either losing the data or suffering some operational failure, the present invention is able to conceal these errors and to continue decoding and presentation of the MPEG data. In certain embodiments, this involves maximizing the available data that contain no errors to conceal those portions of the data that do include errors. The present invention is operable to accommodate various layers while performing error concealment, including the MPEG transport stream layer, the video layer, and the audio layer.
