Refer to the NTSC Composite Receiver Model at the end of this glossary when studying this definition. After the (M) NTSC or (B, D, G, H, I) PAL video signal makes its way through the Y/C separator, by either the chroma bandpass, chroma trap, or comb filter method, the colors are then decoded by the chroma demodulator. Using the recovered color subcarrier, the chroma demodulators take the chroma output of the Y/C separator and recovers two color difference signals (typically I and Q or U and V).
