What are the ways to control multiple TVs?

Question

TVs

It is necessary to hang several TVs (> 10 pieces) on some object. One of the following types of content should be played on each TV:

1. Signal from one satellite receiver (i.e. analog)
2. From another (analog again)
3. Media content from the media server (apparently digital)
4. Video from surveillance cameras ( figure, RTSP)

Moreover, you need to centrally manage the entire system. Roughly speaking, choose on which TV set what we are now showing, while not walking with remote controls throughout the room.

As I see it as an ideal solution to the problem: there is a certain device with a bunch of outputs and various inputs and a web interface that allows you to arbitrarily switch inputs with outputs. The problem is that I did not find such devices.

Another option is TV sets with a single control console installed on the server. Again, I don't know who can do that.

Tell me how to solve such a problem? There is only one requirement - everything should be done remotely, and not in front of a TV set. And preferably in groups, not one at a time.

How is it generally done in all sorts of restaurants and other public places?

Answer 1

Look at this article from habr.

Answer 2

I did through "HDMI Extender with IR".
Then there are devices, such as matrix video splitter and so on.
smart homes also have similar systems.

Answer 3

In such situations, some nettop is usually screwed to the TV, and then everything is connected to the network
