High-Definition Multimedia Interface (HDMI) is the first
digital interface to combine uncompressed high-definition
video, multichannel audio, and intelligent format and
command data in a single cable.

The HDMI standard was introduced in December 2002, and
HDMI 1.2 was released in August 2005. HDMI is supported by
many leading consumer electronics manufacturers as well as
motion picture studios, and cable and satellite operators.

The HDMI connector is compact and is somewhat similar
to a USB connector.

Use this serial interface to connect audio/video equipment,
such as DVD players, a set-top box, and A/V receivers with an
audio and/or video monitor, such as a digital TV over a single
cable. HDMI supports standard, enhanced, and high-definition
video. It has a bandwidth of up to 5 Gigabytes so it supports
all HDTV standards and has bandwidth to spare for future
applications.

HDMI is backward compatible with DVI equipment such as
PCs, TVs, and other electronic devices using the DVI standard.
The DVI device simply ignores the extra data.

HDMI offers significant benefits over older analog A/V
connections. It provides superior video and audio clarity
because there is no signal loss from digital-to-analog
conversions. HDMI supports resolutions of 1920 x 1080p and
multiple audio formats from standard stereo to multichannel
surround sound. Plus it provides two-way communication
between the video source and the digital TV, enabling simple,
remote, point-and-click configurations.

HDMI is emerging as the connection standard for HDTV
and the consumer electronics market. Because HDMI transmits
all signals over one cable, it’s quite desirable for home theater
electronics and systems. It greatly simplifies the installation of
home entertainment systems by eliminating the tangle of
cables running behind the system. It’s also very cost-effective
because only one cable is needed.
