HDMI. The High-Definition Multimedia Interface has been around since the early 2000s, and was developed for consumer electronics devices such as Blu-ray Disc players and HDTVs. However, HDMI has also seen wide use in graphics cards and computer displays. Its connector’s wide rectangle with two beveled corners can be adapted to DVI.
HDMI is notable for its ability to transmit both HD video and audio simultaneously. For example, a quality cable rated for 10.2Gbps operation can carry a 3D, 1080p movie and the film’s HD surround sound soundtrack.
The current specifications, HDMI 1.4a and 1.4b, offer a variety of optional features such as advanced 3D formats, Ethernet support, and more. Version 1.4b adds support for 1080p video at 120 Hz. HDMI 2.0, which will bring higher bandwidth capabilities, had not been released as we went to press. There are mini and micro versions of HDMI for mobile devices such as smartphones and camcorders.
