What does HDCP mean?
- High-bandwidth Digital Content Protection
- High-bandwidth Digital Content Protection 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. Types of connections include DisplayPort, Digital Visual Interface, and High-Definition Multimedia Interface, as well as less popular, or now defunct, protocols like Gigabit Video Interface and Unified Display Interface. 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. Before sending data, a transmitting device checks that the receiver is authorized to receive it. If so, the transmitter encrypts the data to prevent eavesdropping as it flows to the receiver. In order to make a device that plays material protected by HDCP, the manufacturer must obtain a license from Intel subsidiary Digital Content Protection LLC, pay an annual fee, and submit to various conditions. For example, the device cannot be designed to copy; it must "frustrate attempts to defeat the content protection requirements"; it must not transmit high definition protected video to non-HDCP receivers; and DVD-Audio material can be played only at CD-audio quality by non-HDCP digital audio outputs. HDCP does not allow copying permitted by fair use laws.
