3 Overview
The Kramer
VM-2HDCPxl
is an HDCP (High-Bandwidth Digital Content
Protection) compatible 1:2 distribution amplifier for DVI-D (Digital)
signals. Since high-resolution DVI signals are very sensitive to cable quality
and to PCB layout, the
VM-2HDCPxl
uses a uniquely designed PCB which
includes all buffering, conditioning and amplifying circuitry to provide two
high-level output signals.
In particular, the
VM-2HDCPxl
:
x
Distributes signals having resolutions up to WUXGA, including
all HDTV formats
x
Has a bandwidth of 2.25Gbps
x
Supports the DDWG DVI 1.0 standard
x
Consists of a built-in re-clocking block that re-generates the DVI
signal, so that several units may be cascaded
x
Can read and store, in non-volatile memory, the EDID

x
Has I-EDIDPro™ Kramer Intelligent EDID Processing™, an
intelligent EDID handling and processing algorithm that ensures
Plug and Play operation for HDMI systems
block
from one of the outputs, so it can then provide the EDID
information to the DVI source even if the display device is not
connected
x
Has three DVI-I connectors, which are compatible with all types
of DVI cables
x
Is a cost-effective solution for distributing the TMDS signals used
for DVI, and uses state-of-the-art line drivers on both outputs
3.1 About
HDCP
The High-Bandwidth Digital Content Protection (HDCP) standard
2
, 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.
