Digital component video is defined by ITU-R BT.601 (formerly CCIR 601) standard and uses the Y'CbCr colorspace. Like Analog Component Video it gets its name from the fact that the video signal has been split into two or more components, that are then carried on multiple conductors between devices. Digital component video is slowly becoming popular in both computer and home-theatre applications. Component video is capable of carrying signals such as 480i, 480p, 576i, 576p, 720p, 1080i and 1080p, although many TVs do not support 1080p through component video.
