YUV
Last modified: Thursday, January 11, 2007 

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 graphics hardware. 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.
