A color television system is identical except that an additional signal known as chrominance controls the color of the spot. Source: Internet

A monochrome signal is identical to a color one, with the exception that the elements shown in color in the diagram (the color burst, and the chrominance signal) are not present. Source: Internet

At certain times, the chrominance signal represents only the U signal, and 70 nanoseconds (NTSC) later, the chrominance signal represents only the V signal. Source: Internet

Colour encoding Both the PAL and the NTSC system use a quadrature amplitude modulated subcarrier carrying the chrominance information added to the luminance video signal to form a composite video baseband signal. Source: Internet

But a spectrum analyzer instrument shows that, for transmitted chrominance, the frequency component at the subcarrier frequency is actually zero energy, verifying that the subcarrier was indeed removed before transmission. Source: Internet

Depending on the video standard, the chrominance subcarrier may be either quadrature-amplitude-modulated ( NTSC and PAL ) or frequency-modulated ( SECAM ). Source: Internet
