[ADV7392] CGMS-A and Closed Caption.

Hello,

 

I have questions about copy guard function of ADV7392.
When we want ADV7392 to output video with Macrovision,
I think we should set register from 0xE0.
I have questions about CGMS-A and closed caption.

 

Question 1:
About CGMS-A, we understand we should set Addr:0x99 [6:5].
But when copy guard information is received, what should we set?

 

Question 2:
About Closed caption, we understand we should set Addr:0x83.
But when copy guard information 2bit is received, what should we set?

 

Thank you.

Best regards.
Tamu
