YPbPr Totally Explained

Everything about Ypbpr totally explained

YP_BP_R (often written YPbPr and also referred to as Y/P_B/P_R, YP_RP_B, P_RP_BY, P_BP_RY, Y/Pb/Pr, YPrPb, PrPbY, PbPrY, Y/R-Y/B-Y, Y(R-Y)(B-Y), Y, R-Y, B-Y) is a color space used in video electronics, in particular in reference to component video cables. YP_BP_R is the analog version of the YC_BC_R color space; the two are numerically equivalent, but YP_BP_R is designed for use in analog systems whereas YC_BC_R is intended for digital video.
Being that people often get tongue-tied trying to say YP_BP_R quickly they're also commonly referred to as Yipper cables. YP_BP_R is commonly called "component video", but this is a misnomer, as there are many other types of component video (the most common is RGBHV or RGB/HV, aka VGA / D-SUB).
YP_BP_R is converted from the RGB video signal, which is split into three components, Y, P_B, and P_R.

Y carries luma (brightness) information.
P_B carries the difference between blue and luma (B − Y).
P_R carries the difference between red and luma (R − Y).

A green signal isn't sent as the colour can be interpolated using the blue, red and luma information. This is done to save bandwidth.
See the YC_BC_R page for the defining equations.
Some video cards come with Video In Video Out (VIVO) ports for connecting to component video devices.
