  • Patent number: 8736770
    Abstract: A method for processing signals in a communication system may include performing by one or more processors and/or circuits integrated within a single digital television (DTV) receiver chip, demodulating a wirelessly received digital inband signal and a wirelessly received digital out-of-band signal. The demodulating may include equalizing the received digital inband signal and the received digital out-of-band signal. The demodulated digital inband signal and the demodulated digital out-of-band signal may be error corrected. One or more TV channels may be generated based on one or both of the error corrected demodulated digital inband signals and/or the error corrected demodulated out-of-band signals. The wirelessly received digital inband signal may include a VSB signal, a NTSC signal and/or a QAM signal. The one or more processors and/or circuits may perform decoding the wirelessly received digital inband signal.

  • Patent number: 7940337
    Abstract: Systems and methods for processing signals in a communication system are disclosed and may include demodulating a wirelessly received inband signal and a wirelessly received out-of-band signal via a DTV receiver. One or more TV channels may be generated based on the demodulation of the wirelessly received inband signal and a wirelessly received out-of-band signal. The received inband signal may include a VSB signal, a NTSC signal and/or a QAM signal. The processing may also include determining whether the wirelessly received inband signal includes an analog signal or a digital signal. The digital signal may be error corrected, and the error corrected digital signal may be equalized. The analog signal may be decoded, and an audio output may be generated based on the decoding of the analog signal.

  • Patent number: 7250987
    Abstract: Certain embodiments of the invention may be found in a method and system for a vestigial side band (VSB), quadrature amplitude modulation (QAM), NTSC, out-of-band (OOB) receiver that is integrated in a single chip. The single chip integrated digital television (DTV) receiver provides plug and play DTV receiver capability for handling both North American digital cable television and digital terrestrial broadcast television compatible systems. The integrated DTV receiver may receive all standard-definition and high-definition digital formats (SDTV/HDTV) and an on-chip NTSC demodulator handles NTSC video. An output of the NTSC demodulator may be directed to an external broadcast television system committee (BTSC) or Zweiton M decoder, or it may be sent to an on-chip audio BTSC compliant decoder. The single chip integrated DTV receiver may also comprise an integrated out-of-band QPSK receiver, which may be adapted to, for example, handle a CableCard compliant with the CableCard Specification.

  • Patent number: 7034893
    Abstract: A digital television signal is intercepted by a plurality of antennas to produce a corresponding plurality of input signals. The antennas have different directionality so they can be combined in a way that reduces multipath echoes. In one embodiment, the antennas are arranged to operate in a diversity or scanned array mode. In another embodiment, the antennas are arranged to operate in a adaptive phased array mode. The input signals intercepted by the antenna are subjected to vestigial sideband (VSB) processing to produce a single VSB processed signal, which is decoded to form a display drive signal. A plurality of input signals in a VSB receiver having a plurality of antennas with different directionality are evaluated to determine how the input signals should be combined to reduce multipath echoes.
