HDCP - High-bandwidth Digital Content Protection

HDCP is a content protection specification to protect digital entertainment content across the DVI/HDMI interface. The HDCP provides a robust, cost-effective and transparent method for transmitting and receiving digital entertainment similar to DVI/HDMI-compliant digital displays. HDCP encrypts the data transmitted between the DVI/HDMI connector on the graphics adapter and the display. To provide this support, both the graphics adapter and the display need to have an HDCP transmitter and receiver respectively.
