HDCP Block

2.6

HDCP Block

The HDCP block implements the datapath decryption block of the HDCP content protection scheme

of DVI. Please refer to the HDCP Specification 1.0 for details. The state machines of the HDCP

specification are split between the external microcontroller and this block. Only the high speed and

data intensive cryptographic functions are implemented in this block to maintain maximum system

level flexibility.
