Component Video Cable Pinout

Color Signal Function
Green Y Carries luma (brightness or luminance) and synchronization (sync) information
Blue PB Carries the difference between blue and luma (B − Y)
Red BR Carries the difference between red and luma (R − Y)

The designation for analog component video signals. The "Y," "Pb" and "Pr" are sets of three inputs or outputs on video equipment and TVs. The three cables used in a YPbPr connection represent higher quality than the single-wire composite cable commonly used to hook up video equipment, because the brightness and color components of the signal are maintained separately. The YPbPr signals are derived from the red, green and blue (RGB) colors captured by a scanner or digital camera, and RGB is converted into brightness and two color difference signals (B-Y and R-Y) for TV/video.
