Introduction

The High Definition Multimedia Interface (HDMI) is

an emerging consumer electronics standard that is

fast gaining acceptance by manufacturers of digital

entertainment products. HDMI offers an efficient 

one-cable interface for High Definition (HD) video

and audio content between receiver/playback

devices and display devices. 

Typical receiver/playback devices include cable

boxes, DVD players, satellite receivers, and High

Definition tuners as well as personal computers.

Display devices connected via HDMI include LCD

displays, plasma displays, and projection units.

Thanks to the simplicity of setup and the resulting

quality of the presentation, consumers are accepting

HDMI as a “must-have” item for the full HD experience.

HDMI uses the existing Digital Video Interface (DVI)

architecture and adds capability for High Definition

Audio and High-Bandwidth Digital Content Protection

(HDCP). The latter technology enables true copy

protection of high-quality digital movie content.

HDCP is receiving an enthusiastic response from the

entertainment industry, which is advocating its use in

all HD consumer products.
