premiumBox + wifi - HDMI, HDCP signal is switched to SCART after turning off the

I have a few doubts and questions related to the NC + PremiumBox + WiFi decoder, which I was forced to block the previous Philips PVR decoder.
I have a bedroom through the wall and connected (I always had) TV via AV via SCART - Cinch AV cable. And everything was ok. Currently, after turning off the TV in the main room (HDMI), the decoder is blocked and displays a SCART board about the harmfulness of copying. I am not copying anything? And when I do not hear something and it shines, I can't sleep. Hence my problem.
1. Please explain to me what this copying and relation with excluding TV is about ???.
2. I read that you can get around it by buying a not cheap splitter or an active cable.
3. What is this security feature, if you just pull out the HDMI plug from the TV and the SCART signal is OK.
4. The signal dies immediately after inserting the HDMI plug, even when the TV is disconnected from the mains. So it is not an active connection, but a passive one. It is enough to safely disconnect any end, just advise which one? Because if I fan the HDMI plug, this socket will go to hell quickly.

The decoder software was written this way. Buy yourself an HDMI splitter and that's it.

I more or less knew that, thanks. But maybe the HDMI cable can be manipulated. Breaking this connection should result in the absence of the OFF signal. But which wire is it in the cable?

I still do not know how to manipulate it so that the decoder does not "see" turning off the TV. Let me remind you when the TV is completely turned off from the mains, it is the same as when the TV is on. So it is a question of pulling one of the HDMI terminals to the ground ???.

Before your colleague starts fiddling with HDMI cables, please check the status of the HDMI-CEC or HDMI-Control function / option. Both TV and set-top box.

This operation of the decoder suggests that these functions are enabled.

I have not solved the problem, I pull out the HDMI plug, then turn off the TV and then the decoder works on the SCART output. I do not know if it is not a shame not to improve the decoder software? I will order a cheap HDMI splitter and check if it is enough to switch to an unused input before turning off? I'm not closing because someone can find a solution.

How did you not solve? You know how to get around.

The switch helped, although the problem is because I have to switch to an empty place before turning off the TV.
