ABSTRACT:
An apparatus and method for processing content signals received from a plurality of different, and possibly dissimilar, signal sources, such as different satellite networks, and providing a display based on the content of those signals. The apparatus includes a tuner/demodulator for receiving content signals and demodulating the received content signals as programming bitstreams, and one or more access control devices for descrambling any conditional access present in the demodulated programming bitstreams. The apparatus further includes a processor, such as a system chip, which is responsible for all command and control functions. The system chip evaluates conditional access to determine whether the bitstream needs decryption, descrambling, or both, and processes a bitstream from one of the multiple signal sources for display on a suitable output device.
