Component Video
In producing a color picture from light, our color television system starts out with three channels of information; Red, Green, & Blue (RGB). This is certainly one form of component video. In the process of translating these channels for use in distribution, they are often first converted to Y, R-Y, and B-Y or Y Pb Pr. This is another form of component video. The term component describes a number of elements that are needed to make up the picture. It could be argued that an S video signal is also a component signal. A composite video signal on the other had contains all the information needed for the color picture in a single channel of information. Much higher program production quality is possible in the component domain because analog compression is used to place the three channels of component information into the single channel of composite information. Once that compression take place it is extremely difficult to get back the original quality of the component signal. One of the advantages DVD has over the laserdisc format is that it is component based. | ||||

COMPONENT VIDEO
System of signal recording and processing that maintains the original video elements separately rather than combined (encoded) into a single, composite signal.
System of signal recording and processing that maintains the original video elements separately rather than combined (encoded) into a single, composite signal.
Component video
A video signal consisting of three separate color signals (or components), usually RGB (red, green, blue), YCbCr (Luminance, Chroma minus Blue, and Chroma minus Red), or Y, R-Y, B-Y (Luminance, Red minus Luminance, Blue minus Luminance.) Composite video A video signal that contains all the luminance, chroma and timing (or sync) information in one composite signal. Compositing: The process of layering media on top of each other to create collages or special effects.

Component Video
Not to be confused with Composite video. A video signal transmitted as at least three separate components using separate wires or cable. The most common formats are: RGB (separate signals for red, green, and blue), and analog component video (R/Pb/Pr, luminance together with a signal based on red). Using simple circuits, RGB needed to display a picture can be easily derived from the latter. In order to get RGB using simple circuits, there must be at least three components supplied. (In algebra, if a problem has three "unknowns" there must be at least three equations or relationships supplied in order to solve it.) S-video has two components, luminance and color, but an elaborate circuit (using phase decoding and demodulation) is needed to disassemble the "color", or "C" signal into two other components. These together with the luminance make up the three components that simple circuits can in turn convert into RGB.

Video, component
Used in Hi8 and SuperVHS cameras, component video splits the single composite video signal into colors (RGB) and improves the quality by adding a luminance or brightness (Y) channel and a color/chroma intensity (C) channel. Superior to composite video.
