Signal processing methods and systems for cross-color suppression. A chrominance signal extracted from a composite TV signal by s Y/C separator is provided to a chroma demodulator to produce a baseband chrominance signal. A chroma regulator regulates the baseband chrominance signal to obtain a regulated baseband chrominance signal. The baseband chrominance signal and the regulated baseband chrominance signal are provided to a chroma mixer to determine a final chrominance signal. The chroma mixer determines the final chrominance signal according to image similarity calculated by an image similarity calculator.
