In particular, HDMI
1
:
• 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
3
cable
• Supports standard, enhanced, high-definition video, and multi-

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
5
, 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
Th
e Extended Display Identification Data (EDID
6
) is a data-structure,
provided by a display, to describe its capabilities to a graphics card (that is
connected to the display’s source). The EDID enables the VM-4H 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.

4 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
5 HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a
simple, cost-effective manner
