ABSTRACT:
Disclosed is an apparatus for receiving a selected channel of a signal having a plurality of channels, each channel having a plurality of subchannels. A parabolic reflector, low noise amplifier and block converter receive the signal. A tuner detects the selected channel in the received signal and provides a detected signal corresponding to the selected channel. A demodulator demodulates the detected signal into a baseband signal corresponding to the selected channel, the baseband signal being modulated with the subchannels of the selected channel. An analog bus is connected to the demodulating means for providing the baseband signal. A first demodulator connected to the analog bus demodulates a first subchannel of the subchannels of the baseband signal and provides a signal representative of the first subchannel. A second demodulator connected to the analog bus demodulates a second subchannel of the subchannels of the baseband signal and provides a signal representative of the second subchannel. A digital bus is connected to the first and second demodulators. A power supply is connected to the analog bus and so that the analog bus carries power supply signals to the demodulators. The digital bus carries data in, data out, clock and enable signals to the demodulators.
