What is HDCP?
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 DisplayPort, Digital Visual Interface (DVI), High-Definition Multimedia Interface (HDMI), Gigabit Video Interface (GVIF), or Unified Display Interface (UDI) connections, even if such copying would be permitted by fair use laws.HDCP is licensed by Digital Content Protection, LLC, a subsidiary of Intel.
HDCP's stated purpose is to protect high definition content during transmission from a source device to a display device. Three systems were developed to achieve that goal.
● Authentication process prevents non-licensed devices from receiving content.
● Encryption of the actual data sent over DisplayPort, DVI, HDMI, GVIF, or UDI interfaces prevents eavesdropping of information.
● Key revocation procedures ensure that devices that have been compromised and cloned can be blocked from receiving data.
