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.

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.
Use this 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.
