Hello.

I have a question about HDMI Rx device (ADV7611, ADV7612, ADV7614 etc.).

Is there any method that HDMI Rx device knows whether HDCP authentication (checking revocation list) result is good or no good ?

 

I think HDMI source device (media player etc.) should know the result, and sink device does not have to know it.
But in this case, the customer will design their repeater system (HDMI Rx and Tx are used), and the system has to know the result of OK or no good of checking revocation list because unknown video (visually undesirable video) can not be displayed (sent) by the system's spec.
So customer wants the HDMI Rx device (ADV761x) to know the result in order that the system sends black video when HDCP authentication (checking revocation list) is no good.
I think HDMI Rx device does not have a register to know the result directly.
Do you have any good idea?

 

Thank you.
Best regards.
