Communications Computer Industry Companies Computer Science Data Graphics Hardware Internet and Online Services Mobile Computing Multimedia Networks Operating Systems Programming Software Standards Types of Computers World Wide Web   HDCP Last modified: Tuesday, January 15, 2008  Short for high-bandwidth digital-content protection, a specification developed by Intel for protecting digital entertainment content that uses the DVI interface. HDCP encrypts the transmission of digital content between the video source, or transmitter -- such as a computer, DVD player or set-top box -- and the digital display, or receiver -- such as a monitor, television or projector. HDCP is not designed to prevent copying or recording of digital content but to protect the integrity of content as it is being transmitted. Implementation of HDCP requires a license obtainable from the Digital Content Protection, LLC, which then issues a set of unique secret device keys to all authorized devices. During authentication, the receiver will only accept content once it demonstrates knowledge of the keys. Furthermore, to prevent eavesdropping and stealing of the data, the transmitter and receiver will generate a shared secret value that is consistently checked throughout the transmission. Once authentication is established, the transmitter encrypts the data and sends it to the receiver for decryption.   Digital Connection: What is HDCP? Products compatible with the HDCP scheme such as DVD players, satellite and cable HDTV set-top-boxes, as well as few entertainment PCs requires a secure connection to a compliant display, the process often described as the handshake.

HDCP: What It Is and How To Use It April 2002 article from EDN Access gives a comprehensive explanation of HDCP, including diagrams and the mathematical calculation used to encrypt the digital data.
