Protection) An encryption system for enforcing digital rights management (DRM) over DVI, DisplayPort and HDMI interfaces. The copy protection system (DRM) resides in the computer, DVD player or set-top box. If it determines the video material must be protected, it encrypts the signal via HDCP and transmits it to the display system, which decrypts it. See

HDMI.
