Component video

From GEAR Software Knowledgebase

Jump to: navigation, search

A color video transmission or storage system that uses three signals to describe the video. There are two forms of component video - either RGB (using separate red, green, and blue signals), or YCbCr, YPbPr, YUV (which describes the video as a chroma plus color difference signal). When the three component signals are combined, the video can be displayed. Component video can be stored or transmitted either as a set of analog signals, or as a digital signal. Component video systems are used for most professional video applications, as they generally allow for higher quality than composite video systems. Increasingly, component video systems are being offered in consumer equipment, such as DVD players, televisions and digital video camcorders. The MPEG-2 video encoding system used in DVD video uses the color difference component video system.
