P B carries the difference between blue and luma ( B − Y).With color, Y still represents intensity but it is a composite of the component colors. Before the advent of color television, the Y axis on an oscilloscope display of a video waveform represented the intensity of the scan line. It uses BT.709-2 matrix coefficients and digital YCbCr. Y carries luma (brightness or luminance) and synchronization (sync) information.YP BP R is converted from the RGB video signal, which is split into three components: Y, P B, and P R. Some video cards come with video-in video-out (VIVO) ports for connecting to component video devices.įurther information: YCbCr § Technical details YP BP R is commonly referred to as component video by manufacturers however, there are many types of component video, most of which are some form of RGB. Sync is carried on the Y channel and is a bi-level sync signal, however, in HD formats a tri-level sync is used and is typically carried on all channels. The EOTF (gamma correction) may be different from common sRGB EOTF and BT.1886 EOTF. YP BP R is gamma corrected YC BC R color space (it is not analog YUV that was used for analog TV, though component video is an analog interface) the two are numerically equivalent but YP BP R is designed for use in analog systems while YC BC R is intended for digital video. YPbPr or Y'PbPr, also written as YP BP R, is a color space used in video electronics, in particular in reference to component video cables. The green cable carries Y, the blue cable carries P B and the red cable carries P R. YPbPr is the analog video signal carried by component video cable in consumer electronics.
