Summary:A colour television decoder for separating chrominance signals from a colour video signal (A) has a variable two dimensional finite impulse response filter comprising delay lines (1-5), which provide signals representing an array of picture points around the picture point being imaged, and a variable combiner (6) which linearly combines the signals with variable coefficients. A picture analyser (7) analyses the picture and controls the variable coefficients so as to control the filter response to separate the chrominance signal (D). The luminance signal may be separated by subtracting the chrominance signal from the delayed colour video signal.
