3.1 Defining EDID
The Extended Display Identification Data (EDID
1
) is a data-structure, provided by
a display that describes its capabilities to a graphics card (that is connected to the
display’s source). The EDID enables the PC or laptop to “know” what kind of
monitor is connected to the output. The EDID includes the manufacturer’s name,
product type, timing data supported by the display, display size, luminance data
and (for digital displays only) pixel mapping data.
3.2 About HDMI—General Description
High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital

cable
•
Supports standard, enhanced, high-definition video, and multi-channel
digital audio
6
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
7
, and user-friendly connector
•
Is backward-compatible with DVI (Digital Visual Interface)
•
Supports two-way CEC 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

4 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
5 HDMI technology has been designed to use standard copper cable construction at up to 15m
6 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
7 HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a simple, cost-
effective manner
