RCA Video vs Audio Cables

Video and audio cables are so named because they carry video and audio signals from a source device like a player or camera to a destination like speakers, TV, or a recording device. In most cases there is really no difference between the cables as the only difference is the signal that they actually carry. A good example of this is the RCA cable. The RCA cable is typically composed of 3 cables that would carry 1 for video and 2 for audio (left and right channels). The three cables can be easily swapped without compromising performance.
RCA or composite cables -- the classic red, white and yellow cables you used to use to plug in your Set Up Box to the television -- are still available on most televisions and some computer monitors.

What Is RCA?

If you’ve ever hooked a CD player or DVD player to your TV, you likely used an RCA cable. A simple RCA cable has three color-coded plugs extending from one end of a cable that connects to three correspondingly colored jacks on the back of a TV, projector from Buydig.com or another output device. These old style cables carry audio and video signals from the component device to the output device. The two most common types of RCA cables are composite video and component. The colors used in composite RCA cables are usually red, yellow, and white cables for composite video. Composite video is analog, or non-digital, and carries all the video data in one signal. Because analog video is made up of three separate signals to begin with, squeezing them into one signal reduces the quality somewhat. Composite video isn’t designed to be used for high-definition analog or digital video signals. Component cables are more sophisticated cables that are sometimes used on HD TVs. Component cables have three video lines usually colored red, green and blue and two audio lines that are colored red and white or black. The two red lines usually have an additional color added to distinguish them. Component RCA cables are capable of much higher resolutions than composite video cables. Although an HDMI cable is a more modern way to connect devices, there are still plenty of opportunities to use RCA cables. An RCA cable can be used to connect a variety of audio and video devices, such as camcorders to TVs or stereos to speakers. Most high-end camcorders have all three RCA jacks, so the signal entering or leaving the camcorder goes through three separate channels resulting in a high-quality transfer.
