Component video is a type of analog video that is transmitted in two or more signals. It differs from Composite video which combines the various elements into a single signal. All types of analog video signals, which are also called components, need to carry the information needed to reproduce the proper color of the image. The most simple type is known as RGB, or red, green, and blue. It is through the mixing of these colors that the actual on screen color is produced.
There is a more complex signal where a single color carrying signal called a luminance signal is used. This luminance, or light signal, is combined with other components known as chrominance that contain the color information. This advanced signal is capable of remarkable and more accurate color reproduction, and this is what is usually referred to when one speaks of Component Video today.
Component video has been widely used for producing signals such as 480p, 576p, 720p, and above. Its ability to process the progressive scanning signals, represented by the letter p, is what made it popular in Plasma and LCD television. Component video signals can also be used in 1080i and 1080p formats, but DVI and HDMI connections are generally thought to produce superior results at that resolution size.
It is important to be aware that many new DVD players, and televisions require that settings be adjusted to account for the type of input/output signal being used. The use of Component signals may not be the default setting. Likewise, they might not be defaulted for progressive scan, and the failure to adjust the settings will result in a very inferior image reproduction.
