Black Box Explains

Digital extension technologies.

In-line extenders, installed in the middle of a link

or as transmitter/receivers, extend signals over their native

cabling with no signal conversion occurring.

Non-networked CATx extenders use transmitters

and receivers to extend converted signals over ordinary

(non-networked) UTP cabling. They’re very cost-effective

and enable much longer distances than what’s ordinarily

possible with digital video cabling.

Fiber-based cabling extenders use transmitters

and receivers to extend digital signals over secure,

interference-free (non-networked) optical fiber. These

extenders enable you to deliver video at much longer

distances than copper.

Networked IP extenders use transmitters

and receivers to extend video signals over a

network’s UTP infrastructure. They work by

packetizing media streams for delivery over

Ethernet wiring.

DVI and HDMI interfaces.

DVI (Digital Video Interface) is the standard digital

interface for PCs (in contrast to HDMI, which is more

commonly found on HDTV devices).

The DVI standard is based on transition-minimized

differential signaling (TMDS). There are two DVI formats: single-link and

dual-link. Single-link cables use one TMDS-165 MHz transmitter, and

dual-link cables use two. The dual-link cables double the power of the

transmission. A single-link cable can transmit a resolution of 1920 x 1200 vs.

2560 x 1600 for a dual-link cable.

Several types of DVI connectors are available, most commonly:

DVI-D, a digital-only connector for use between a digital video

source and monitors. DVI-D eliminates the analog pins.

DVI-I (integrated), which supports both digital and analog RGB

connections. It can transmit either a digital-to-digital signal or an

analog-to-analog signal. It is used on products instead of separate

analog and digital connectors. If both connectors are DVI-I, you can

use any DVI cable, but a DVI-I is recommended. (NOTE: For a DVI-I to

DVI-D display converter, see page 62).

DVI-A (analog), which is used to carry a DVI analog signal from a

computer to an analog VGA device, such as a monitor. If one or both

of your connections are DVI-A, use this cable. If one connection is DVI

and the other is VGA HD15, you need a cable or adapter with both

connectors as long as you do not require an active analog/digital

connector.

DVI-D, Dual Link

HDMI (High-Definition Multimedia Interface

) was

the first digital interface to combine uncompressed

HD video, up to eight channels of uncompressed digital audio, and

intelligent format and command data in a single cable. It is now the

defacto standard for consumer electronics and HD video, although it

is beginning to face competition from the newer DisplayPort interface.

HDMI offers an easy, standardized way to set up AV equipment

over one cable. Use it to connect equipment such as digital signage

players, set-top boxes, and AV receivers with HDTVs and video

projectors. If the HDMI equipment supports higher-resolution HDMI

standards, you can also connect 3D displays.

HDMI also supports multiple audio formats from standard stereo

to multichannel surround sound. In addition, the interface provides

two-way communications between the video source and HDTV,

enabling simple, remote, point-and-click configurations.

It also supports HDCP (High-bandwidth Digital Content Protection),

which prevents the copying of digital audio and video content sent

over HDMI cable. If you have a device between the source and the

display that supports HDMI but not HDCP, your transmission won’t

work, even over an HDMI cable.

HDMI is backward compatible with DVI equipment; a DVI-to-HDMI

adapter can be used without a loss of video quality to enable the

connection. Because DVI only supports video signals, not audio, the

DVI device simply ignores the extra audio data.
