component signals in a multiplexed digital format.
Like
analog component video,
[The common name for 'component analog video (CAV)'] 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 used in both computer and home-theatre applications, such as . It was the internal signalling ''(as opposed to, e.g.
