3.1 About HDCP
The High-Bandwidth Digital Content Protection (HDCP) standard
3
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 and encrypted transmission of digital signals.
The Extended Display Identification Data (EDID
4
) is a data-structure,
provided by a display, to describe its capabilities to an HDCP source. The
EDID enables the VM-4HDCPxl 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.
1 Suitable for resolutions up to UXGA at 60Hz, and for all HD resolutions
2 Lets you use the EDID default value when no display from which to read the EDID is connected
3 Developed by Intel
4 Defined by a standard published by the Video Electronics Standards Association (VESA)
