Patent ID: 8248536

Claim:
An apparatus, for use in a receiver configured to receive an electronic video signal, wherein the video signal includes a luminance component that is encoded with amplitude modulation and a chrominance component that is encoded with frequency modulation on a carrier frequency, the apparatus comprising: a first filter device configured to receive the video signal and output a substantial portion of the luminance component as a received luminance component; a second filter device configured to receive the video signal and output a substantial portion of the chrominance component as a received chrominance component; a leakage detector device configured to receive the carrier frequency of the chrominance component and output a leakage detection signal; and a variable signal adder configured to receive the leakage detection signal and to make a determination as to whether to add a portion of the received chrominance component to the received luminance component; and wherein the first filter device is further configured to receive the leakage detection signal, compare the leakage detection signal to a first threshold and adjust the filtering bandwidth of the first filter device based on the comparison.
