Abstract
Systems and method are provided for luma-chroma separation. A demodulator system demodulates a composite video signal to produce at least two baseband chroma signals. A given baseband chroma signal contains chroma information for one of a plurality of video frames comprising the composite signal. A three-dimensional (3-D) comb filter removes luma information from a given baseband chroma signal by combining sets of at least two baseband chroma signals to form a 3-D filtered baseband signal.
