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.

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.

Abstract: A computer method and system provides on-demand transformation between objects of a source programming model and corresponding objects in a target programming model. For different source objects in the source programming model, the invention creates respective target objects. For every created target object, the invention system and method create a respective proxy object. Where a source object has multiple features, the proxy object triggers transformation of a feature only upon access of that feature and the corresponding target object. The present invention operates transparently to a client. Thus, clients do not have to call transform on the feature (children and references) of the source object before accessing any feature of the target object.

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.

Abstract: A change-set validator is invoked at the end of every transaction on a target model. The change-set validator may also be used as a transaction committer wherein after validating the change-set, changes are made to the source model, thereby bringing both models in sync. A Transformation Adapter deals with transformation of source meta-model objects to target meta-model objects. The Inverse Transformation Adapter is a special case of the change-set validator used also as the transaction committer, and deals with transformation of target meta-model objects to source meta-model objects. The change-set validator can be implemented as a rule. The change-set committer can be implemented as a Semantic Procedure.

Abstract: A discrete Fourier transform (DFT) filter bank with stack shift capability, configured, for example, as an analyzer, but equally applicable to a synthesizer, and implemented as a polyphase filter. The DFT filter bank includes a complex modulator for multiplying the input signals x0(m), x1(m) . . . xM?1(m) by a complex modulator e?2?ko(m). In order to keep the coefficients for the polyphase filter real, the coefficients are modulated by a DFT twiddle factor e?2?ko?/M. The use of the DFT twiddle factor enables the hardware to be reduced significantly. For example, for an 8 phase 203 tap filter, only 8 selectable negators are required as opposed to 211 for known DFT filter banks.
