In particular, HDMI:

•Provides a simple interface between any audio/video source, such as a set- top box, DVD player, or A/V receiver and video monitor, such as a digital flat

LCD / plasma television (DTV), over a single lengthy cable

SIMPLICITY - 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

LENGTHY CABLE - HDMI technology has been designed to use standard copper cable construction at up to 15m

•Supports standard, enhanced, high-definition video, and multi-channel digital

audio on a single cable

MULTI-CHANNEL DIGITAL AUDIO - 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

•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 cable, and user-friendly connector

HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a simple, cost-effective manner

•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

•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
