Publication number: 20060125965Abstract: The invention relates to a method for separating a chrominance signal from a composite video baseband signal. In order to improve the separation, it is proposed that the composite video baseband signal is filtered sequentially in any order by means of spatial comb filter means in horizontal and vertical direction and by means of field comb filter means in vertical direction and temporally to obtain said chrominance signal. Thereby, the advantages of a spatial and a temporal filtering at different vertical frequencies can be combined. The invention relates equally to a chrominance-luminance separator comprising filter means for realizing the proposed method.Type: ApplicationFiled: December 5, 2003Publication date: June 15, 2006Inventor: Jean-Jacques Richard Vandenbussche
