Monochrome or luminance information. Monochrome means one color. In the color television system, the black and white portion of the picture has to be one “color” gray, D6500, 6500° K as defined by x and y values in the 1939 CIE color coordinate system. The black and white signal in the S or Component video path is separate from the color information.

Signals used by color television systems to convey color information (not luminance) in such a way that the signals go to zero when there is no color in the picture. Color difference signal formats include: R-Y and B-Y; I and Q; U and V; PR and PB. The figure below shows general color difference waveforms along with the Y signal. The color difference signals must first be converted in their RGB form before they can recreate the picture. Refer to the RGB discussion to view what the RGB version of the color bar signal looks like. The color difference signals in the figure are centered around 0 volts, but this is only true for the SMPTE/EBU N10 standard. The NTSC and M11 color difference standards have the most negative portions of the color difference signals riding on a voltage of 0 volts or close to it.

Color mapping is distinguished by the following: a) Each pixel contains a color number (or address) referring to a position in a color map. Each pixel has “n” bits, so there are “2 to the n” color map addresses.
b) A hardware device called the color map defines the actual RGB values for each color.

The amplitude region of the composite video signal below reference-black level in the direction of the synchronizing pulses.

A method of correcting color errors which are fundamental in any three primary color additive reproducing system, by electrically changing the R, G, and B signals with a matrix or masking amplifier which mixes (usually subtracts) the signals in a very precise predetermined amount. The form is generally as follows: R out = R in + a(G-R) + b(R-B) a, b, c, d, e, and f are G out = G in + c(G-R) + d(B-G) referred to as the masking B out = B in + e(R-B) + f(B-G) or correction coefficients

Αντίστοιχο χρώμα ορίζεται ως ερέθισμα που, κάτω από ορισμένες διαφορετικές συνθήκες προσαρμογής, θυμίζει την ίδια εμφάνιση χρώμα ως ένα άλλο ερέθισμα όταν είδε κάτω από το αρχικό κράτος της προσαρμογής. Ταίριασμα χρώματος, αντιστοιχεί είναι μια υποκειμενική κρίση.

A color map is just a numbered list of colors. Each color is specified in terms of its red, green, and blue components.
