Patent ID: 7477325

Claim:
An apparatus for processing a near-baseband, received digitized television signal comprising: a video carrier recovery circuit adapted to: receive a video carrier recovery circuit input signal, said video carrier recovery circuit input signal including a video carrier signal; detect a phase offset of said video carrier signal; generate a phase adjustment signal based on said phase offset; produce a video carrier recovery circuit output signal from said video carrier recovery circuit input signal and said phase adjustment signal; a filter circuit to: receive a filter circuit input signal, said filter circuit input signal including components in a frequency range that is expected to contain a digitized audio signal; produce a filter circuit output signal excluding said components in said frequency range; and a selection circuit adapted to switch between: a first configuration, wherein said near-baseband, received digitized television signal is said video carrier recovery circuit input signal and said video carrier recovery circuit output signal is said filter circuit input signal; and a second configuration, wherein said near-baseband, received digitized television signal is said filter circuit input signal and said filter circuit output signal is said video carrier recovery circuit input signal.
