D-Terminal

The 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.

This article is about the video connector. For the item used in Digimon Adventure 02, see Digivice.

Some items sold outside Japan use the connector as well. Notable examples are Canon's XH-A1 DVC high-definition camcorder and Panasonic's AG-HVX200 DVCPro HD camcorder.

D1~D5 types
Two D-Video connectors (D4) on an HDTV. The much smaller D-Terminal should not be confused with the similarly-shaped but larger VGA connector.

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.[1]

Compatibility Questions

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. Furthermore, the PSP-3000 marks the possibility of interlace I/O.
