ABSTRACT:
Computer controllable apparatus for receiving and demodulating a satellite broadcast signal. A programmable radio frequency tuner/demodulator demodulates the broadcast signal to produce a baseband output signal. A video demodulator then demodulates the baseband output signal to produce a video output signal. First and second programmable audio frequency tuner/demodulators further demodulate the baseband output signal to produce first and second audio output signals. A data demodulator further demodulates the second audio output signal to produce a data output signal.
