It does, but YOU don't.   From what I've read about other products
that do this, you have access to modify the bits in a graphics overlay
plane.  Your overlay plane and the decrypted HDMI signal are merged in
a hardware component and then HDCP is slapped back onto the outgoing
HDMI signal.   You never have access to unencrypted graphics bits from
the incoming HDMI signal.  IMO, it's a neat hack.
