Definition: HDCP


(High-bandwidth Digital Content 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.
