3.1 About HDMI
High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital1
audio/video interface, widely supported in the entertainment and home cinema
industry. It delivers the highest high-definition image and sound quality. Note that
Kramer Electronics Limited is an HDMI Adopter2 and an HDCP Licensee3.
In particular, HDMI:
Provides a simple4 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
lengthy5 cable

to-analog conversions

currently used in A/V systems is reduced
