Acronym for “High-Definition Multimedia Interface.” HDMI is the first and only industry-supported, uncompressed, all-digital audio/video interface. It was designed to deliver crystal-clear, digital audio and video via a single cable, thereby dramatically simplifying cabling and providing consumers with the highest-quality home theater experience.

HDMI provides an interface between any audio/video source, such as a set-top cable or satellite box, DVD player, or A/V receiver and an audio and/or video monitor, such as a digital television (DTV), over a single cable.

HDMI supports standard, enhanced, or high-definition video, plus multi-channel digital audio. It transmits all ATSC HDTV standards and supports 8-channel, 192kHz, uncompressed digital audio and all currently-available compressed formats (such as Dolby Digital and DTS). HDMI 1.3 adds additional support for Dolby TrueHD and DTS-HD lossless digital audio formats with bandwidth to spare to accommodate future enhancements.
