ADV7619 how to disable HDCP handshaking

Hi,

 

We have found some ADV7619 with no "-P" parts. These seems to be more available than the -P parts, ironically! We signed an agreement with HDCP in order to have these installed legally but we want these parts to not decode HDCP by default. I have found a way to avoid HDCP decoding by setting the HDCP_A0 bit to 1, i.e. sets the I2C address to HDCP port to 0x76 instead of 0x74. However, I am concerned that maybe in some setups, this protection will not be enough.

Do you have any tricks on how to disable HDCP decoding by its register interface or any means?

 

Regards,

Jérôme
