主权项 1. A baseband YC separation circuitry for video signal processing, the circuitry comprising: a cross luminance (Y) suppression circuit configured to detect luminance motion between a current frame and a previous frame and to suppress dot crawl artifacts or chroma residue present in a Y signal; a cross chroma (U) suppression circuit configured to detect U chroma motion between the current frame the previous frames and to suppress cross color artifacts or luminance residue present in U signals; a cross chroma (V) suppression circuit configured to detect V chroma motion between the current frame the previous frames and to suppress cross color artifacts or luminance residue present in V signals; and a baseband motion detector configured to differentiate between moving and stationary pixels such that an optimum comb filter can be selected to maximize effectiveness of YC separation, wherein the baseband YC separation circuitry is configured to receive Yin, Uin and Vininput signals separately and to output clean luminance signals Yout, Uout and Vout.
