Patent ID: 7401349

Claim:
An indoor unit of a satellite television ground system comprising: tuning circuitry operative to simultaneously tune a first satellite television signal from a first satellite and a second satellite television signal from a second satellite, said first satellite television signal and said second satellite television signal being received from an outdoor unit of the satellite television ground system via a communications line; first processing circuitry in communication with the tuning circuitry and operative to obtain carrier frequency offset data of one of the first and second satellite television signals; oscillator circuitry operative to generate an oscillator signal; and second processing circuitry in communication with the first processing circuitry and the oscillator circuitry, the second processing circuitry operative to frequency stabilize the oscillator signal utilizing the obtained carrier frequency offset data, and provide the frequency stabilized oscillator signal via said communications line to uplink circuitry and downlink circuitry of the outdoor satellite television signal unit.
