RCA Cable

The RCA cable is named for the Radio Corporation of America, which first used it in the 1940s to connect phonographs to amplifiers. It entered popular home use in the '50s and is still in use today. The two most common types are composite video and component. The colors used in composite RCA cables are usually red and white or black for right and left audio channels and yellow for composite video. Composite video is analog, or non-digital, and carries all the video data in one signal.
