How does HDCP discourage pirating of protected content?
HDCP offers content protection for the link between devices; not generally for inside a device. HDCP performs encryption on the data just before the TMDS PHY in a source, and decrypts it just after the TMDS PHY in a sink. HDCP offers a system renewability feature that allows content providers to revoke keys from devices dynamically from the originating content source.
