A D-Terminal or D-tanshi (Ｄ端子) is a type of analog video connector found on Japanese consumer electronics, typically HDTV, DVD, Blu-ray, D-VHS and HD DVD devices. It was developed by the EIAJ (Electronic Industry Association of Japan) in its standard, RC-5237, for use in digital satellite broadcast tuners. In appearance it is a small flat trapezic connector, the same connector as the AAUI connector used by Apple Computer for some time to connect to ethernet.
It is the same for YPbPr usual component video connectors used for analog HDTV in mostly rest of the World, as S-Video to Composite video. Main reason of quite wide usage was earlier adoption of HDTV(as the same with color TVs to black TVs in 1960s) in Japan, comparing even to other highly developed territories like Europe or Northern America. 
- 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.
With the aforementioned diagrams, consumers should take careful consideration regarding the input and output terminals. Purchased products such as the PlayStation Portable (PSP-2000) are equipped with the (D2) interface. However, since the release of System Software Ver.5.00, the interface has been changed to (D1). Since 2010, the PSP's I/O system has adopted the progressive I/O interface (D1). Furthermore, the PSP-3000 marks the possibility of interlace I/O.
