4 PT-571/PT-572+ - 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.
3.2 About the Power Connect™ Feature
The Power Connect™ feature here means that only one unit in a system, the
transmitter or receiver, needs to be connected to a power source when the
devices are within 90m (270ft) of each other. The Power Connect™ feature
applies as long as the cable can carry power and the distance does not exceed
90m on standard CAT 5 cable. For longer distances, heavy gauge cable should be
used (CAT 5 cable is still suitable for the video/audio transmission, but not for
feeding the power at these distances).
3.3 About HDCP—General Description
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.
3.4 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.
