  • Receive data flow path using a single FEC decoder
    Patent number: 9106265
    Abstract: Data flow control in a television receiver controls the output of the frequency deinterleaver (FDI) and the time deinterleaver (TDI) to prioritize processing control information having transmission parameters needed for processing data, thereby facilitating use of one FEC decoder.
    Type: Grant
    Filed: November 4, 2011
    Date of Patent: August 11, 2015
    Assignee: Silicon Laboratories Inc.
    Inventors: Frederic Nicolas, Olivier Souloumiac, David Rault
  • Techniques to control power consumption in an iterative decoder by control of node configurations
    Patent number: 8555131
    Abstract: A method for controlling power consumption of an iterative decoder based on one or more criteria is described. The method may include progressively enabling and disabling nodes of the iterative decoder to perform iterative decoding on a demodulated signal to provide a decoded signal with minimal variation of a supply voltage.

  • Techniques to control power consumption in an iterative decoder by control of node configurations
    Patent number: 8433970
    Abstract: A method for controlling power consumption of an iterative decoder based on one or more criteria is described. The method may include performing iterative decoding on a demodulated signal to provide a decoded signal, receiving information regarding the iterative decoding, and based on the information controlling a number of nodes of the iterative decoder to enable during a next iteration of the iterative decoding.

  • Reducing power consumption in an iterative decoder
    Patent number: 8341486
    Abstract: A method for controlling power consumption of an iterative decoder based on one or more criteria is described. The method may include performing iterative decoding on a demodulated signal to provide a decoded signal, determining whether the iterative decoding is suffering an impairment, and terminating the iterative decoding responsive to the determination of the impairment, otherwise continuing the iterative decoding to provide the decoded signal.

  • Multi-standard digital demodulator for TV signals broadcast over cable, satellite and terrestrial networks
    Patent number: 8237869
    Abstract: A multi-standard single-chip receiver for digital demodulation of TV signals broadcasted over any of multiple digital television means, e.g., satellite, cable and terrestrial, is provided. The receiver can receive and demodulate a variety of different signal types received from one or more up-front tuners. A demodulator architecture in accordance with an embodiment of the present invention can be optimized to re-use common demodulation processing blocks for the different incoming signal types.
