Patent number: 9392208Abstract: An implementation exits a power saving mode for fixed and periodic active periods of time to receive a separate burst transmission from a first stream during each of the corresponding active periods of time. The first stream is received at a first-stream burst data rate. The first stream includes data configured to be displayed at a first playback rate that is substantially less than the first-stream burst data rate. During the active periods of time, data is received from a second stream at a second-stream rate. The second stream includes data configured to be displayed at a second playback rate that is substantially the same as the second-stream rate. After receiving each of the burst transmissions from the first stream during the active periods of time, the power saving mode is entered for corresponding fixed and periodic power-saving periods of time while waiting for another burst from the first stream.Type: GrantFiled: November 13, 2013Date of Patent: July 12, 2016Assignee: Thomson LicensingInventors: Paul Gothard Knutson, Kumar Ramaswamy, Joshua Lawrence Koslov, Manoj Viswambharan, Benyuan Zhang, Wen Gao, Yik Chung Wu

Patent number: 8687747Abstract: Methods and apparatus for symbol timing recovery are provided. Both a coarse symbol timing recovery method and apparatus, and a fine symbol timing recovery method and apparatus are described which can be used jointly for symbol recovery, for example in phase shift keying receivers. The coarse method involves the use of differential correlations and finding the time difference in peak values of the correlation results. The fine method involves interpolation of a received digital signal, followed by filtering and timing error detection. The error detection signal is further filtered and used to control the interpolator. The methods provide for robust symbol timing synchronization.Type: GrantFiled: May 28, 2010Date of Patent: April 1, 2014Assignee: Thomson LicensingInventors: Paul Gothard Knutson, Dirk Schmitt, Wen Gao

Patent number: 8418210Abstract: A satellite television ground system, particularly for a make or break satellite television signal system, includes an outdoor unit and an indoor unit that are in communication with each other via a single coaxial cable and an optional separate single conductor for power. The satellite television ground system is operative to measure and reverse frequency conversion errors utilizing DSP techniques, allowing for more precise generation and transmission of uplink signals from the satellite television ground system. Control data for the system is sent via a low data rate connection on a power cable thereof, or by a narrowband signaling channel via a coax cable. The system also utilizes a single reference oscillator to drive the various frequency synthesizers and the like. The satellite television ground system utilizes related oscillators for the uplink and downlink sections. Carrier frequency offset in the downlink is measured in a carrier tracking loop part of a television signal demodulator.Type: GrantFiled: February 26, 2002Date of Patent: April 9, 2013Assignee: Thomson LicensingInventors: Paul Gothard Knutson, Kumar Ramaswamy, Max Ward Muterspaugh
