I have been reading documents to understand better about HDCP but it is still not clear. I think my question apply to both the ADV7612 and ADV7511.
1.      One document say the HDCP status is communicate/update using ‘background’ port. What is ‘background’ port? Is it the pin DDCSDA and DDCSCL on the HDMI connector?
2.      In the user guide UG-216, it said the decryption status is read from internal ROM of the ADV7612 (see below), is that done from the factory for every chip?
