I would like to know if there is a way to detect HDCP content at the HDMI input using the ADV7619 chipset. I checked for the HDMI_CONTENT_ENCRYPTED bit in HDMI 0x05 register and this one doesn't seem to toggle when I plug an HDCP video.
I'm using the IC that doesn't have the HDCP keys. Is it still possible to detect this state without them?
We just want to advertise the user that the current stream will not be decrypted.
