digital flat LCD / plasma television (DTV), over a single lengthy4cable
•Supports standard, enhanced, high-definition video, and multi-channel
digital audio5on a single cable
•Transmits all ATSC HDTV standards and supports 8-channel digital
audio, with bandwidth to spare to accommodate future enhancements and
requirements
•Benefits consumers by providing superior, uncompressed digital video
quality via a single cable6, and user-friendly connector
•Is backward-compatible with DVI (Digital Visual Interface)
•Supports CEC, two-way communication between the video source (such
as a DVD player) and the digital television, enabling new functionality
such as automatic configuration and one-button play
•HDMI has the capacity to support existing high-definition video formats
(720p, 1080i, and 1080p, 2K and 4K), standard definition formats such as
NTSC or PAL, as well as 480p and 576p.

3 With video and multi-channel audio combined into a single cable, the cost, complexity, and confusion of multiple cables
currently used in A/V systems is reduced
4 HDMI technology has been designed to use standard copper cable construction at up to 15m
5 HDMI supports multiple audio formats, from standard stereo to multi-channel surround-sound. HDMI has the capacity to
support Dolby 5.1 audio and high-resolution audio formats
