Abstract
An adaptive system for separating chrominance and luminance components from composite video includes a delay element having a central output tap and pairs of further output taps symmetrically disposed about said further tap. Samples from each pair of taps are subtractively combined, filtered and scaled. These samples are then applied to a decoder which determines the pair of taps providing the smallest filtered and scaled difference. Samples from the pair of taps generating the smallest difference and samples from the central output tap are then combined to produce either comb filtered chrominance/luminance or bandpass/lowpass filtered chrominance/liminance.
