Patent ID: 8537285

Claim:
A picture carrier recovery block for processing an input signal to provide phase-adjusted video information for a desired channel signal that is transmitted according to an analog transmission standard, wherein the picture carrier recovery block comprises: a carrier recovery filter for filtering the input signal to produce a filtered picture carrier signal; a first phase rotator coupled to the carrier recovery filter for receiving the filtered picture carrier signal and providing a first phase adjustment to produce a phase-adjusted filtered picture carrier signal; a Vestigial Side Band (VSB) filter for filtering the input signal to produce filtered video information; a second phase rotator coupled to the VSB filter for receiving the filtered video information and providing a second phase adjustment to produce the phase-adjusted video information; and a carrier recovery block coupled to the first and second phase rotators, the carrier recovery block being configured to process the phase-adjusted filtered picture carrier signal to compensate for phase perturbations and to produce a phase control signal that is provided to the first and second phase rotators to control an amount of the first and second phase adjustments.
