Patent ID: 7932958

Claim:
A video device to output a video image corresponding to a selected channel which is one of a plurality of channels of a broadcast spectrum, the video device comprising: a video receiver to receive an input video signal having a carrier frequency which is associated with the selected channel and to generate a baseband video signal which is representative of the input video signal, the video receiver including: a tuner to receive the input video signal and to generate the baseband video signal which is representative of the input video signal; a video decoder, coupled to the tuner, to generate a video output signal which is associated with the selected channel, wherein the video decoder generates the video output signal using the baseband video signal, the video decoder including: a detector to detect a signal quality of the baseband video signal, wherein, in response to detecting a degradation in quality of the baseband video signal, the detector outputs a signal which is representative of the degradation in quality of the baseband video signal; and a video output circuit, coupled to the video decoder to receive the video output signal and the signal which is representative of the degradation in quality of the baseband video signal, to: (i) generate video data, which is a time-averaged representation of the video output signal, using data which is representative of a plurality of video frames of the video output signal which are sequential in time, and (ii) output the video data which is the time-averaged representation of the video output signal.
