So I wanna to realize the funcation of switching input source automatically to an alternative input source, and switching back when the singnal comes back. I think it'll be possible via script, but I failed. Can somebody please help me to solve the problem? I cannot find any hint from the forum, perhaps I ran the wrong way.

But the program I am broadcasting is mute all the time, actually it is ISS live broadcasting. So I cannot realize this function by voice detection. And the most reliable way I think is the recognition of the pause screen.

By the way,the pause screen isn't stable, it flickers. Thank you for your reply!

You initially asked for when you lost signal but this is totally not the case as you are still having signal jus not the footage you want you are highjacking. Even then there is no consistency in the image you want to trigger on to be able to compare image effectivly. Might try a compare on the first image for match and add a time table to act on for when its in night position

I mean that the pause screen indicates the lost of signal,which shows picture and word is the problem I want to solve, rather than the black picture.
