re. ADV7604.  Detecting HDCP with non-HDCP part.

We are using the non-HDCP part, but would like to know that the incoming video is encrypted HDCP.  When I read either IO register 6f or the HDMI register 04 and 05, an HDCP encrytped input seems meaningless.  I see indications that a key was received, that there were no errors, and that the input is not encrypted.  Only when it is a non-encrypted source does it seem to make sense.  Is there a way to detect that the input is HDCP?
