Patent ID: 7453526

Claim:
An integrated circuit device to output video signals corresponding to a selected channel which is one of a plurality of channels of a broadcast spectrum,the integrated circuit device comprising: an amplifier to amplify an analog video signal having a desired carrier frequency which is associated with the selected channel; a mixing circuit, coupled to the amplifier, to receive the analog video signal and to (i) mix the analog video signal with a complex sinusoid having a frequency substantially equal to the carrier frequency of the analog video signal and (ii) output a first baseband video signal having an in-phase component and a quadrature component; local oscillator circuit, coupled to the mixing circuit, to generate and output the complex sinusoid signal; baseband demodulator circuitry, coupled to the mixing circuitry, to generate and output a second baseband video signal, which corresponds to the selected channel, using the first baseband video signal; and video decoder circuitry, coupled to the baseband demodulator circuitry, to generate a formatted video signal using the second baseband video signal, wherein the formatted video signal corresponds to the selected channel of the broadcast spectrum, and wherein the video decoder circuitry outputs the formatted video signal as a plurality of video frames and, in response to detecting a degradation in the quality of the second baseband video signal, outputs a video frame which is different from a video frame which corresponds to the second baseband video signal having a degradation in quality.
