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.
