Analog color video signals include luminance, brightness (Y) and chrominance (C). Each pixel has two values, which are luminance and chrominance. The resulting subcarrier sidebands is also known as "chroma" or "chrominance". In the above, Y refers to luminance samples, and C to chrominance samples. The chroma/chrominance of video engineering is formed from weighted tristimulus components, not linear components. The compromise can improve text appearance when luminance detail is more important than chrominance. Similarly, the chroma/chrominance of video engineering differs from the chrominance of color science. Saturation is directly related to the amplitude of the chrominance signal. First, SECAM uses frequency modulation to encode chrominance information on the sub carrier. Detects the absence of chrominance information in a color encoder input. This allows black-and-white receivers to display NTSC color signals by simply ignoring the chrominance signal. With more backlight, a higher chrominance is available and a color image display is seen. I and Q represent the chrominance information. March traveled to France to record the album "Chrominance Decoder" with Bertrand Burgalat's label Tricatel.
