Patent ID: 8174621

Claim:
A digital video decoder comprising: a chrominance demodulator comprising an input port coupled to receive a composite video baseband signal (CVBS) signal; a first output port to provide a first color signal (U′); and a second output port to provide a second color signal (V′); and a first filter comprising a first input port coupled to the first output port of the chrominance demodulator to accept the first color signal (U′); a second input port coupled to the second output port of the chrominance demodulator to accept the second color signal (V′); a third input port coupled to receive the CVBS signal; an output port to provide a first luminance signal based on the first color signal (U′), the second color signal (V′) and the CVBS signal; and a mixer comprising a first plurality of input ports coupled to receive a plurality of different first color signals, including the first color signal U′, a second plurality of input ports coupled to receive a plurality of different second color signals, including the second color signal V′, a third plurality of input ports coupled to receive a plurality of different luminance signals comprising the first luminance signal and a notch filtered luminance signal; mixing logic coupled to the first, second and third pluralities of input ports to receive the plurality of different first color signals, the plurality of different second color signals, and the plurality of different luminance signals, a first output port to provide a first mixed color signal (U mix ), a second output port to provide a second mixed color signal (V mix ), and a third output port to provide a mixed luminance signal (Y mix ).
