HDCP
High-bandwidth Digital Content
Protection: A “key” encoded into the
HDMI/DVI signal that prevents video
data piracy. If a source is HDCP coded
and connected via HDMI/DVI without
the proper HDCP decoding, the
picture is put into a “snow vision” mode
or changed to a low resolution. For
normal content distribution the source
and the display device must be
enabled for HDCP “software key”
decoding.
