YUV is the color space used in PAL, and is preferred for video signals. YUV and RGB can be converted back and forth.
A modified form of the component RGB video signal. The black and white (luminance) part of the signal is removed from the red and blue and added to the green. This gives greater detail to the picture, as the human eye perceives detail in green better than red or blue
Color model which describes color information in terms of luminance (Y) and two chrominance channels (U,V). The YUV space is commonly used in video, and easily supports color subsampling.
