It is similar to the (digital component video) and the (NTSC). |

It specifies 1 luminance and 2 chrominance components. These parameters are related by a linear transform to the RGB coordinates. |

The luminance carries the black and white information. |

The U and V chrominance carry the chromatic information. They are often down-sampled without loss of visual quality (YUV 4:4:4 to YUV 4:2:2). They are proportional to the Cb and Cr components of the YCbCr color system (B-Y and R-Y respectively). |
