Color Reproductivity
Each color displayed on the TV screen is implemented by a pixel on color coordinates which have an X and Y axis.
For example, when a pixel on the X coordinate 0.65 and the Y coordinate 0.74 is displayed as a
color and it becomes visible on the TV screen. While the possible color coordinate area is very
wide, the color coordinate area of the signal broadcast from a broadcast station is smaller than
that of possible color coordinates. Moreover, a TV provides a smaller color coordinate area than
that of the signal from the broadcasting station even though the size of the color coordinate area
varies depending on the TV model. In general, Color Reproductivity is used as follows:
The Color reproductivity of a TV is a certain % of NTSC. This means the TV displays that
particular % of the color coordinate area of the NTSC signal broadcast by the broadcasting
station. In general, a CRT TV provides the highest functional color reproductivity.
