The '''D-Terminal''' or '''D-tanshi''' ({{lang|ja|Ｄ端子}}) is a type of analog video connector found on Japanese consumer electronics, typically [[High-definition television|HDTV]], [[DVD]], [[Blu-ray]], [[D-VHS]] and [[HD DVD]] devices. It was developed by the [[Electronic Industries Association of Japan|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 trapezoidal connector, the same connector as the [[Apple Attachment Unit Interface|AAUI]] connector used by [[Apple Computer]] for some time to connect to [[ethernet]].

Some items sold outside Japan use the connector as well. Notable examples are [[Canon (company)|Canon's]] [[List of Canon camcorders#Canon XH-A1(s)/XH-G1(s)|XH-A1]] DVC high-definition camcorder and [[Panasonic|Panasonic's]] [[List of Panasonic camcorders#AG-HVX200, AG-HVX200A (2005, 2006)|AG-HVX200]] [[DV (video format)#DVCPRO HD|DVCPro HD]] camcorder.

==D1~D5 types==
[[Image:D4 terminal.jpg|thumb|left|190px|Two D-Video connectors (D4) on an HDTV. The much smaller D-Terminal should not be confused with the similarly-shaped but larger [[Video Graphics Array|VGA]] connector.]]
A D-Terminal connector carries a [[component video]] signal ([[YPbPr|YP<sub>B</sub>P<sub>R</sub>]]). A device with a D5 connector can understand and display the following video signals:
*D1 [[480i]]{{0|0p}} (525i)： {{0|00p}}720&nbsp;×&nbsp;480 [[interlaced video|interlaced]]
*D2 [[480p]]{{0|0i}} (525p)： {{0|00i}}720&nbsp;×&nbsp;480 [[progressive scan|progressive]]
*D3 [[1080i]]{{0|p}} (1125i)： {{0|p}}1920&nbsp;×&nbsp;1080 interlaced
*D4 [[720p]]{{0|0i}} (750p)： {{0|0i}}1280&nbsp;×&nbsp;720 progressive
*D5 [[1080p]]{{0|i}} (1125p)： {{0|i}}1920&nbsp;×&nbsp;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 connector|BNC]] component connection.<ref name="D-Terminal to Component cable adapter">[http://hiphing.manufacturer.globalsources.com/si/6008800048020/pdtl/RCA-cable/1001315592/D-terminal-to-Component-Cable.htm D-Terminal to Component cable adapter] {{webarchive|url=https://web.archive.org/web/20090116210608/http://hiphing.manufacturer.globalsources.com/si/6008800048020/pdtl/RCA-cable/1001315592/D-terminal-to-Component-Cable.htm |date=2009-01-16 }}</ref>

==Compatibility Issues==
It is not always a given that output devices support all lower versions of the standard, so customers must take care to buy compatible products. For example, the [[PlayStation Portable]] ([[PSP-2000]]) initially supported only the 480p (D2) mode. System Software Ver. 5.00 added 480i (D1) support for the "PS one Classics" games, but not native PSP games. The later [[PSP-3000]] and [[PSP Go]] models have 480i support for all games.
