HDMI (High-Definition Multimedia Interface) is a new kind of digital audio and video connector that promises to replace all connectors currently used by DVD players, TV sets and video monitors. The idea is to use a single cable instead of several cables when connecting your DVD player to your TV set, for example. This new connection standard was developed by Hitachi, Matsushita (Panasonic/National/Technics), Philips, Silicon Image, Sony, Thomson (RCA) and Toshiba.
The greatest advantage brought by this standard is the use of digital connection for both audio and video, bringing the best quality possible. Nowadays digital audio connection is done thru a single cable, but it is very rate to see devices like DVD players using digital video connection (the most popular video connections are S-Video and Component Video, both analog). The digital video connector that exists today is called DVI. You can learn more about video connection types available today by reading our Video Connectors tutorial.
