YPbPr

From Wikipedia, the free encyclopedia

Jump to: navigation, search
YPBPR is the analog video signal carried by component video cable in consumer electronics. The green cable carries Y, the blue cable carries PB and the red cable carries PR.

YPBPR[1] 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.[2] YPBPR is commonly called "component video", but this is a misnomer, as there are many other types of component video (RGBHV, RGBs, RGsB, Y/C, etc.).

Some video cards come with Video In Video Out (VIVO) ports for connecting to component video devices.

[edit] Technical details

Further information: YCBCR

YPBPR is converted from the RGB video signal, which is split into three components, Y, PB, and PR.[3]

  • 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).

Sending a green signal would be redundant, as it can be derived using the blue, red and luma information.

YPBPR cables are not physically different from composite video cables and can be used interchangeably.
