If so, the transmitter encrypts the data to prevent eavesdropping as it flows to the receiver. Before sending data, a transmitting device checks that the receiver is authorized to receive it. The system is meant to stop HDCP-encrypted content from being played on unauthorized devices or devices which have been modified to copy HDCP content.
Types of connections include DisplayPort (DP), Digital Visual Interface (DVI), and High-Definition Multimedia Interface (HDMI), as well as less popular or now deprecated protocols like Gigabit Video Interface (GVIF) and Unified Display Interface (UDI). High-bandwidth Digital Content Protection ( HDCP) is a form of digital copy protection developed by Intel Corporation to prevent copying of digital audio and video content as it travels across connections.
