A color encoding system used for analog television, such as
NTSC and PAL. The YUV color model represents the
human perception of color more closely than the standard RGB model used in
computer graphicshardware.
In YUV, Y is the luminance (brightness) component while U and V
are the chrominance (color) components.
The YUV colour space The reasons to use the YUV decomposition are multiple. Firstly, a conversion of an RGB signal (such as the one used on your monitor) to YUV requires just a linear transform, which is really easy to do with analogue circuitry and it is cheap to compute numerically.
