Patent ID: 8570446

Claim:
A receiver for processing received transmission signals to provide at least one of video and audio information for a desired channel signal, wherein the receiver comprises: an analog processing block for providing coarse filtering and amplification to a multi-channel signal to produce a first signal, the coarse filtering being configured to use pass bands that are wide enough to accommodate frequency shifts in the desired channel signal and analog circuitry variability, the first signal being a coarse channel signal; an analog to digital converter coupled to the analog processing block for digitizing the first signal to produce a second signal, the second signal being a digitized coarse channel signal; and a digital processing block coupled to the analog to digital converter for processing the second signal to obtain the information for the desired channel signal, wherein the receiver is configured to track a carrier frequency of the desired channel signal and generate and apply a frequency shift feedback signal to compensate for frequency shifts in the carrier frequency; wherein the digital processing block is configured to additionally apply a known frequency shift for known frequency offset errors in the carrier frequency; and wherein the receiver further comprises an RF processing block coupled to the analog processing block for receiving the transmission signals and providing amplification, filtering and mixing to generate the multi-channel signal, wherein the RF processing block comprises a mixing stage having an oscillator with a coarse step size or a fine step size, and the digital processing block is further configured to compensate for the step size of the oscillator when generating the known frequency shift.
