Features
HDMI.
High-Definition Multimedia Interface (HDMI) is the first
digital interface to combine uncompressed high-definition 
video, multichannel audio, and intelligent format and 
command data in a single cable.
The HDMI standard was introduced in December
2002, and HDMI 1.2 was released in August 2005. 
HDMI is supported by many leading consumer electronics 
manufacturers as well as motion picture studios, and cable 
and satellite operators.
The HDMI connector is compact and is somewhat similar
to a USB connector.
Use this serial interface to connect audio/video
equipment, such as DVD players, a set-top box, and A/V 
receivers with an audio and/or video monitor, such as a digital 
TV over a single cable. HDMI supports standard, enhanced, 
and high-definition video. It has a bandwidth of up to 5 
Gigabytes so it supports all HDTV standards and has 
bandwidth to spare for future applications. 
HDMI is backward compatible with DVI equipment
such as PCs, TVs, and other electronic devices using the DVI 
standard. The DVI device simply ignores the extra data.
HDMI offers significant benefits over older analog A/V
connections. It provides superior video and audio clarity 
because there is no signal loss from digital-to-analog 
conversions. HDMI supports resolutions of 1920 x 1080p 
and multiple audio formats from standard stereo to 
multichannel surround sound. Plus it provides two-way 
communication between the video source and the digital 
TV, enabling simple, remote, point-and-click configurations.
HDMI is emerging as the connection standard for HDTV
and the consumer electronics market. Because HDMI 
transmits all signals over one cable, it’s quite desirable 
for home theater electronics and systems. It greatly simplifies 
the installation of home entertainment systems by eliminating 
the tangle of cables running behind the system. It’s also very 
cost-effective because only one cable is needed.

Recognize any of these situations?
• You wait more than 30 minutes to get through
to a vendor’s tech support.
• The so-called “tech” can’t help you or gives
you the wrong answer.
• You don’t have a purchase order number
and the tech refuses to help you.
• It’s 9 p.m. and you need help, but your vendor’s
tech support line is closed.
According to a survey by Data Communi cations magazine, 90%
of network managers surveyed say that getting the technical support 
they need is extremely important when choosing a vendor. But even 
though network managers pay anywhere from 10 to 20% of their 
overall purchase price for a basic service and support contract, the 
technical support and service they receive falls far short of their 
expectations—and certainly isn’t worth what they paid.
At Black Box, we guarantee the best value and the best support.
You can even consult our Technical Support Experts before you buy if 
you need help selecting just the right component for your application.
