Modular receiver for signals having multiple channels and multiple formats

An apparatus for receiving a selected channel of a signal having a plurality of channels, each channel having a plurality of subchannels, the apparatus comprising:

• means for receiving the signal;
• means for detecting the selected channel in the received signal and providing a detected signal corresponding to the selected channel;
• means for demodulating 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 connected to the demodulating means for providing the baseband signal;
• and
• a chassis connected to the analog bus and having a plurality of slots, each slot for receiving a module to which the baseband signal is supplied, each module for demodulating a subchannel of the baseband signal and providing a signal representative of the subchannel.

A module for use in combination with a receiver having a chassis connected to a digital bus for providing control information and connected to an analog bus providing baseband signal with a plurality of subchannels modulated thereon, said chassis having a plurality of slots, each slot for receiving one of the modules and for supplying a connection to the analog and digital buses, said module comprising:

• means for demodulating the baseband signal including means, responsive to the control information, for selectively controlling a bandwidth of the baseband signal being demodulated;
• means for engaging the analog bus via the slot and for providing the demodulated baseband signal to the demodulating means;
• means for engaging the digital bus via the slot;
• and
• means for supporting the demodulating means, the analog bus engaging means and the digital bus engaging means.
