A D-Terminal connector carries a component video signal (YPBPR).
A device with a D5 connector can understand and display the following video signals:
D1 480i (525i)： 720 × 480 interlaced
D2 480p (525p)： 720 × 480 progressive
D3 1080i (1125i)： 1920 × 1080 interlaced
D4 720p (750p)： 1280 × 720 progressive
D5 1080p (1125p)： 1920 × 1080 progressive
A device with a D-Terminal connector supports that level and lower D-Terminal signal.
 For example, a D4 connector can be used with a D4, D3, D2, or D1 signal, but not with a D5 signal.

It is possible to use a simple breakout cable to connect a D-Terminal connector to a standard 3 RCA jack or BNC component connection.
