I want to be able to check the presence or absence of video signal before switching input port with ADV7627.

However, TMDS can not be detected unless a port is selected.

Therefore, before switching the input port, it can not check the presence or absence of the video signal.

Register is confirming "hdmi lvl raw status 1" at address 0x4D of IO MAP.

Would you advise me how to do it in order to confirm that the video signal is coming to the port you have not selected?
