  • Protocol for control of network or bus attached cable TV set-top box front-end functionality
    Patent number: 8856854
    Abstract: A processor for a cable television set-top box has an interface for coupling the processor to a second processor. The processor also has a port that is coupleable to control a tuner, a demodulator and a DOCSIS module with or without DSG support. The tuner has an output coupled to the demodulator input, and the demodulator has an output to the DOCSIS module input. The demodulator's output is also coupled to a conditional access module controlled by the second processor. The processor issues commands via the port to control at least one of the tuner and the demodulator based on instructions received via the interface from the second processor.
