KRAMER: SIMPLE CREATIVE TECHNOLOGY
Overview

3.1
Using Twisted Pair Cable
Kramer engineers have developed special twisted pair cables to best match
our digital twisted pair products; the Kramer:
BC-DGKat524
(CAT 5 24
AWG), the Kramer:
BC-DGKat623
(CAT 6 23 AWG cable), and the
Kramer:
BC-DGKat7a23
(CAT 7a 23 AWG cable). These specially built
cables significantly outperform regular CAT 5 / CAT 6 / CAT 7a cables.
Note: the
TP-573 / TP-574
cannot work with unshielded cables.

About HDCP
The High-Bandwidth Digital Content Protection (HDCP) standard (developed
by Intel), protects digital video and audio signals transmitted over DVI or DVI
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.
3.3
Defining EDID
The Extended Display Identification Data (EDID
1
) is a data-structure
provided by a display to describe its capabilities to a graphics card (that is
connected to the display’s source). The EDID includes the manufacturer’s
name, product type, timing data supported by the display, display size,
luminance data and (for digital displays only) the pixel mapping data.

About HDMI
High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital
2
audio/video interface, widely supported in the entertainment and home cinema
industry. It delivers the highest high-definition image and sound quality.
In particular, HDMI

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

2 Ensuring an all-digital rendering of video without the losses associated with analog interfaces and their unnecessary digital-
to-analog conversions

4 With video and multi-channel audio combined into a single cable, the cost, complexity, and confusion of multiple cables
currently used in A/V systems is reduced
5 HDMI technology has been designed to use standard copper cable construction at up to 15m
