The connectors are colored as follow: yellow for the composite video, red for the right audio channel, and black
or white for the left audio channel, where stereo is available. The jacks are found on many audio and video
devices. And some TV sets have these jacks somewhere on the front panel to facilitate the connection with video
game consoles, camcorders or digital cameras.

The quality of the cable is very important, when such RCA cables are poor built with a low protection shield,
then the video or audio signal can be noisy.

The composite video transfer, which is modulated onto a RF carrier, is composed from three unique signals
Y, U and V, where Y is the luminance of the image, and U + V is the hue and saturation of the chrominance
channel. A big disadvantage of this system is that every signal requires its own jack, and in many cases,
three or maybe four cables must be connected to achieve the proper settings, and this obviously leads to
a mess of cabling.

Because the RF modulation and demodulation can lose data quality, a video artifact is caused on the picture.
The artifact is known as dot crawl, and is an infamous defect resulting from the crosstalk, where the
intermodulation of chrominance and luminance signals are made.

Because this disadvantage, the system has evolved into S-Video and component video which can maintain
the signals separated. Sometimes can be used comb filters to separate the channels and render more quality
pictures, without artifacts from the composite sources.
