YP[B]P[R] is the analog video signal carried by component video cable in
consumer electronics. The green cable carries Y, the blue cable carries
P[B] and the red cable carries P[R].

*YP[B]P[R]*^[1] is a color space used in video electronics, in particular
in reference to component video cables. YP[B]P[R] is the analog version of
the YC[B]C[R] color space; the two are numerically equivalent, but
YP[B]P[R] is designed for use in analog systems whereas YC[B]C[R] is
intended for digital video.

YP[B]P[R] cables are also commonly referred to as /Yipper/ cables.^[2]
YP[B]P[R] is commonly called "*component video*" by manufacturers, but this
is imprecise, as there are many other types of component video, most of
which are some form of RGB.

Some video cards come with video-in video-out (VIVO) ports for connecting
to component video devices.

Further information: YC[B]C[R]

YP[B]P[R] is converted from the RGB video signal, which is split into three
components: Y, P[B], and P[R].

· Y carries luma (brightness or /luminance/) and synchronization (sync)
information. Y = 0.2126 R + 0.7152 G + 0.0722 B. Before the advent of color
television, the Y axis on an oscilloscope display of a video waveform
represented the intensity of the scan line. With color, Y still represents
intensity but it is a composite
