Patent ID: 7679685

Claim:
A video system ( 100 ) that processes an analog video signal ( 502 ), the analog video signal ( 502 ) comprising luminance information ( 408 ), first chrominance information ( 410 ), and second chrominance information ( 410 ), the video system ( 100 ) comprising: a first time-sampled analog filter ( 506 ) that extracts the luminance information ( 408 ) from a first aliased copy of the analog video signal ( 502 ); a second time-sampled analog filter ( 508 ) comprising a high-pass switch capacitor filter that extracts the first chrominance information ( 410 ) from a second aliased copy of the analog video signal ( 502 ); and a third time-sampled analog filter ( 510 ) comprising a high-pass switch capacitor filter that extracts the second chrominance information ( 410 ) from a third aliased copy of the analog video signal ( 502 ).
