A D-Terminal 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 trapezoid connector, the same connector as the AAUI connector used by Apple Computer for some time to connect to the ethernet.
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.
