3.1 About HDCP
The High-Bandwidth Digital Content Protection (HDCP) standard 1
3.2 Defining EDID
, 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, encrypted transmission of digital signals.
The Extended Display Identification Data (EDID 2
3.3 Recommendations for Best Performance
) is a data-structure,
provided by a display, to describe its capabilities to the source. The EDID
enables the VM-12HDCP to “know” what kind of monitor is connected to
the output. The EDID includes the manufacturer’s name, the product type,
the timing data supported by the display, the display size, luminance data
and (for digital displays only) the pixel mapping data.
Achieving the best performance means:
•
Connecting only good quality connection cables, thus avoiding
interference, deterioration in signal quality due to poor matching,
and elevated noise levels (often associated with low quality
cables)
• Avoiding interference from neighboring electrical appliances and
positioning your VM-12HDCP away from moisture, excessive
sunlight and dust
