YUV is a color model - or [[Color_spaces|color space]] - that consists of one luma (a.k.a. brightness) component, Y, and two chroma components, U and V. As expected, YUV represents color in a different way than [[RGB]], making necessary a [[Color_conversions|color conversion]] when switching from one format to the other.

The YUV color model is used in all video transmission and broadcasting systems (NTSC, PAL, SECAM) because of its compatibility with legacy black-and-white receivers, which can display only the luma (Y) channel of the signal.

Because of the gradual evolvement of the video transmission and broadcasting technology, there are today quite a few different YUV sub-formats, both [[Interleaved|interleaved]] and [[Planar|planar]], such as for example [[YUY2]] and [[YV12]].
