Composite Video Cables

Composite video cables are versatile and familiar standbys like RCA, phono, and coaxial cables that connect to many of the devices in your home. These two-in-one video cables and audio cables transmit steady signals vital to your home entertainment systems. Composite video remains a necessity in the digital age.

How does composite video work?

Composite video cables carry all three parts of the video signal. They carry important information between your player and monitor for clear, crisp video. The three parts are:

  • Luminance
  • Hue
  • Saturation

What is the difference between composite and component video?

Composite video splits the signal into three parts, while component video sends the whole video signal combined into one. Resolutions of up to 480i are possible using a composite cable.

What is a phono input used for?

Phono input, also known as RCA, originated as a way to connect record players and turntables to speakers, but became commonplace due to its versatility. These cables have a central male connector surrounded by a ring that is inserted into the sockets of one or both of the transmitting and receiving devices. They function as both an audio cable and video cable combined into one.

What is an RCA input?

The red, white, and yellow cables are the phono or RCA cables. They come in many styles and carry both audio and video signals in either digital or analog format. Each color tells you what kind of signal it carries:

  • Yellow: composite video.
  • Red: right audio.
  • White: left audio.

What is the AV cable?

A composite AV cable connects to your TV or monitor in three ports. One cable carries the visual signal, while the others send left and right audio. They have been around since the beginning of the home entertainment era and can connect almost anything. This type of cable can connect:

  • Televisions and video players.
  • Stereos and speakers.
  • Desktop computers and screens.

Why do composite cables sometimes buzz?

The part of the composite cable that transmits video or audio, the male, is surrounded by a round ring of metal. This serves to ground the connector. If this ring becomes damaged or bent it stops working as a ground. That's when it begins to make the buzzing sound.

Can you connect composite to HDMI?

There is no such thing as an HDMI composite cable since a cable cannot change the type of signal. An adapter is needed to connect electronics with different signal types. A device with a composite output can be connected to a digital or LCD television through the use of a composite to HDMI adapter.
