Understanding Component Video Cables

What is Component Video? Why do we need it? To get the answer to these questions and more read on.

What Is Component Video?

Component Video is an analogue signal that supports High–Definition (HD) video signals up to 1080p. It is an almost universal standard of video signal transfer with HD Home theatre equipment and is the only common consumer analogue signal to support progressive scan and high–definition resolutions.

Not to be confused with Composite Video which transmits data via a single cable, Component Video splits the video signal into a number of individual channels typically being luminance, blue – luminance, red – luminance. Separate audio cables are required when using Component Video cables as they do not support audio signals.

What Is Component Video Used For?

Component Video cable is used to send HD analogue video signals from one device to another. Being the standard output for DVD players you will find Component Video in most homes around the developed world.

How Does Component Video Work?

Component Video cables are most commonly made using a number of coaxial cables and RCA connectors. Typically there are three signals sent via three coaxial cables with the signals being:

  1. Luminance (represented as =Y, or the colour green)
  2. Blue minus Luminance (represented as =Pb, or the colour blue) and
  3. Red minus Luminance (represented as =Pr, or the colour red)
  4. Commonly represented as Y/Pb/Pr on electronic devices

What Is Component Video Compatible With?

It is possible to use Component Video with a couple of existing analogue and digital technologies. The most common of these is Component Video to VGA (Video Graphics Array). However Component Video compatibility can also include S-Video and SCART technologies. Furthermore, in some circumstances Component Video is compatible with digital technologies such as DVI–A (Digital Video Interface – Analogue) on an extremely limited basis. Most commonly this compatibility is seen with DVI–A Device to a Component Video capable projector. It should be noted that DVI–A to Component Video is not a common conversion due to its limited compatibility.

Are There Competing Technologies To Component Video?

Whilst Component Video is a popular choice of High Definition analogue signal, its popularity with consumers has recently been declining in favour of digital alternatives such as DVI (Digital Video Interface) and HDMI. This is because of the increasingly better imaging quality that is available through the digital signals.

Component Videos Relevance To Today's Technology

A Component Video cable can be found in most homes as most home theatre equipment utilises this technology. However as home theatre equipment makes the move into the digital era we are seeing Component Video Cable running along side HDMI.

Recommended Component Video Cable Length

For optimal cable performance it is recommended that Component Video cables do not exceed 20 meters in length.
