Overview
3
In particular, HDMI:
Provides a simple
1
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
2
cable
Supports standard, enhanced, high-definition video, and multi-channel
digital audio
3
on 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 cable
4
, and user-friendly connector
Is backward-compatible with DVI (Digital Visual Interface)
Supports 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/60), as well as standard definition formats such as
NTSC or PAL
3.2 Defining EDID
The Extended Display Identification Data (EDID
5
) is a data-structure,
provided by a display, to describe its capabilities to an HDMI source. The
EDID enables the
VM-28HDMI
/
VM-212HDMI
/
VM-216HDMI
to
“know” what kind of monitor is connected to the output. The EDID includes
the manufacturer’s name, the product type, the timing data supported by the
display, the display size, luminance data and (for digital displays only) the
pixel mapping data.
1 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
2 HDMI technology has been designed to use standard copper cable construction at up to 15m
3 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
4 HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a
simple, cost-effective manner
5 Defined by a standard published by the Video Electronics Standards Association (VESA)
