ADV7612 HDCP Encryption Status

Hi,

I have an ADV7612 without the HDCP core as my company is not licensed for HDCP. As such the part outputs a black raster when encrypted HDMI is input. However I'd like to let users know when an HDCP signal is present, and I see that there is a register called HDMI_CONTENT_ENCRYPTED - Main Addr, Reg Addr 0x05[6]. However this register always tells me that the input is unencrypted. I'm guessing that this part has the HDCP core depopulated, and as such all of these registers are non-functional? Can someone please clarify that there is no way of determining HDCP presence on a non-hdcp enabled ADV7612?

 

Thanks!
