\nomenclature{\textbf{YUV}}{is a color model which splits luma from chroma, similarly to human sight.. Colors are stored as absolute luma representation and the difference signal between luma and chroma complement components. This color model is used by PAL and NTSC standards. Y stands for the luma component and U and V are the chroma components. U and V are actually color difference components (respectively R-Y and B-Y). In fact YUV signals are created from an original RGB source. The weighted values of R, G, and B are added together to produce a single Y signal, representing the overall luma. The U signal is then created by subtracting the Y from the blue signal of the original RGB, and then scaling; V is created by subtracting the Y from the red, and then scaling by a different factor. Previous black-and-white systems used only luma (Y) information and color information (U and V) was added so that a black-and-white receiver would still be able to display a color picture as a normal black and white picture.}
