When a high definition (HD) multimedia contents such as audio and video travels from a device such as Blu-Ray player across DisplayPort, Digital Visual Interface (DVI), High-Definition Multimedia Interface (HDMI), Gigabit Video Interface (GVIF), or Unified Display Interface (UDI) connections, the signal is encrypted by High-bandwidth Digital Content Protection (HDCP), a form of digital copy protection developed by Intel Corporation.
