YPbPr
From Wikipedia, the free encyclopedia
YPbPr (also referred to as "Y/Pb/Pr", "YPrPb", "PrPbY", "Y/R-Y/B-Y”, “Y(R-Y)(B-Y)”, “Y, R-Y, B-Y”, and "PbPrY" - all are exactly the same thing) is a color space used in video electronics, in particular in reference to component video cables. YPbPr is the analog version of the YCbCr color space; the two are numerically equivalent, but YPbPr is designed for use in analog systems whereas YCbCr is intended for digital video. Being that people often get tongue-tied trying to say YPbPr quickly they are also commonly referred to as "Yipper" cables.[citation needed]. YPbPr is commonly called "component video", but this is a misnomer, as there are many other types of component video (the most common is "RGBHV", aka "VGA").
YPbPr is converted from the RGB video signal, which is split into three components, Y, Pr and Pb.[1]
- Y carries luma (brightness) information.
- Pb carries the difference between blue and luma (B - Y).
- Pr carries the difference between red and luma (R - Y).
a green signal is not sent as the colour can be interpolated using the blue,red and luma information. This is done to save bandwidth.
See the YCbCr page for the defining equations.
