-- About Componant Cables --
A componant cable is used with componant video. Componant video is an analog video signal that has been split into two or more componant
channels. Component video can be contrasted with composite video (NTSC, PAL or SECAM) in which all the video information is combined
into a single line-level signal that is used in analog television. One way of maintaining signal clarity is by separating the
componants of a video signal so that they do not interfere with each other. When a signal is separated in this way it is called "componant video".
S-Video, RGB(analog computer monitor cable), and YPbPr(Componant Cables) signals comprise two or more separate signals so each
is a componant video signal.
YPbPr is a color space encoding scheme that was developed to save on cable bandwidth requirements while separating the signal enough to provide
a quality image. This allows for a much clearer picture when used with DVD players and other forms of media that connect to a television
or monitor. Home theater applications of Componant Cables are becoming less popular as HDMI Cables
are becoming the more popular choice.

- YPbPr is converted from the RGB video signal, which is split into three components, Y, Pb, and Pr.
- Y carries luma (brightness or luminance) and synchonization (sync) information.
- Pb carries the difference between blue and luma (B − Y).
- Pr carries the difference between red and luma (R − Y).
