3.1 About HDMI
High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital
4
audio/video interface, widely supported in the entertainment and home cinema
industry. It delivers the highest high-definition image and sound quality.
In particular, HDMI:
@
Provides a simple
5
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
6
cable
@
Supports standard, enhanced, high-definition video, and multi-channel
digital audio
7
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
1 Suitable for resolutions up to UXGA at 60Hz, and for all HD resolutions
2
The default EDID feature lets you connect the VM-4HDMI without having to connect a display to the output
3 EDID is Extended Display Identification Data
4 Ensuring an all-digital rendering of video without the losses associated with analog interfaces and their unnecessary digital-
to-analog conversions
5 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
6 HDMI technology has been designed to use standard copper cable construction at up to 15m
7 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
