Everyone in the AV community knows HDCP, the high-bandwidth digital content protection protocol. Love it or loathe it, HDCP is now part of everyday AV working lives. It was designed by Intel and adopted by Hollywood as the method by which valued content is secured, primarily to prevent piracy in a real-time environment. In other words, whilst content is being played, as opposed to whilst moving a file. The focus is on the transmission channel, providing protection as content passes from source to sink.
HDCP addresses this with three interlinked systems: Authentication, Encryption, Key Revocation
