The AD9388A is configured to process analog video signal and the ADC HDMI simultaneous mode is enabled. I connect analog source and encrypted HDMI source at the same time. The IC successfully authenticates the source. I can see the analog video source correctly on the monitor.
When I disconnect the HDMI source the analog video signal disappear for short time, then goes back again.
I think the HDMI module causes the problem, when the input signal’s HDCP status changes.
There is no problem when source is not encrypted.
Does anybody know any solution for this problem?
I would be grateful for your help.
