4 VP-424 - Overview
3.1 About HDMI—General Description
High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital
audio/video interface, widely supported in the entertainment and home cinema
industry. HDMI ensures an all-digital rendering of video without the losses associated
with analog interfaces and their unnecessary digital-to-analog conversions. It delivers
the maximum high-definition image and sound quality in use today. Note that Kramer
Electronics Limited is an HDMI Adopter and an HDCP Licensee.
HDMI, the HDMI logo and High-Definition Multimedia Interface are trademarks or registered
trademarks of HDMI licensing LLC.
In particular, HDMI:
•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 cable
SIMPLICITY - With video and mul i-channel audio combined into a single cable, the
cost, complexity, and confusion of multiple cables curren ly used in A/V systems is
reduced
LENGTHY CABLE - HDMI technology has been designed to use standard copper
cable construction at up to 15m
•Supports standard, enhanced, high-definition video, and multi-channel digital
audio on a single cable
MULTI-CHANNEL DIGITAL AUDIO - 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
•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, and user-friendly connector
HDMI provides the quality and functionality of a digital interface while also supporting
uncompressed video formats in a simple, cost-effective manner
•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
•Has the capacity to support existing high-definition video formats (720p,
1080i, and 1080p/60), standard definition formats such as NTSC or PAL, as
well as 480p and 576p

3.2 About HDCP
The High-Bandwidth Digital Content Protection (HDCP) standard developed by
Intel, protects digital video and audio signals transmitted over DVI or HDMI
connections between two HDCP-enabled devices to eliminate the reproduction of
copyrighted material. To protect copyright holders (such as movie studios) from
having their programs copied and shared, the HDCP standard provides for the
secure and encrypted transmission of digital signals.
