Small TV network. Where to get a signal in the absence of satellites?

Given:
Building (hotel), 100 televisions connected to the hotel television network. In turn, the network consists of 5 transmitters with 20 connections each, the signal is received from 10 receivers (there is nothing Russian). There are no satellites with Russian channels (Yamal 202, ABS 1), just as a fact there are none (Southeast Asia, bad location, lowlands, hills, vegetation).
The Internet channel on optics, in principle, is stable, but one (it cost a lot of work to forward, but it was worth it). The provider does not have any IPTV services.
Task:
Provide the building with television - at least 5 Russian channels. It is desirable with a minimum of expenses (everything is of course relative). It is desirable that you do not have to monitor the operation of programs and equipment 24 hours a day.
What development paths do I see:
1. Paid service (such as Karta-TV), we buy local devices compatible with the service and pay a subscription.
Pros:
- Excellent choice of channels
- Easy setup
- You don't need to buy any expensive equipment other than set-top boxes and a switch.
Cons:
- Solve the problem of how to share 1 Internet channel honestly between 5-10 consumers (set-top boxes) and so that it does not slow down and does not interfere with each other.
- Again, the same Picture seems to be the most stable and advertised, but the subscription fee is expensive.
2. Torrent television service.
Pros:
- Free
- Many channels, including from paid resources (Amedia, Rain)
Cons:
- Raw technology, hangs, buggy, bicycles, more or less only AceStream + Browser or AceStream + VLC bundle works.
- There is no set-top box equipment that can work with the stream in hardware, all kinds of android whistles are not suitable (even worse, you need to make a proxy for them).
- Even if you do not pay attention to stability, you still need to figure out how to transmit a signal from a computer to an RCA transmitter, and one computer per channel is somehow bold if done through the RCA video output.
What other options might be available to solve the problem? What other solutions could there be?

Oh, industrial television is not done this way) And your task is reduced to two actions: to receive content and distribute it to subscribers.
For the first action, the following options are possible:
1) The least expensive - we put two on-air antennas on the roof (meter and decimeter), we bring them into a server (servers?) with TV tuners, we capture the air. There is also specialized industrial equipment for this, for example Anevia Flamingo
2) We negotiate with each channel separately and capture their content from each.
3) Indeed, we use paid services. We need to be able to capture their content without proprietary software. To do this, they must provide the ability to pick it up, for example, via HTTP
The second step requires specification. There are expensive solutions and not so much. First you need to decide exactly what transport you will deliver - IP, DVB or analog. Solutions:
1) Expensive - you build a full-fledged cable TV network in a hotel, buy a content delivery system (for example, Appear, but there is cheaper), install a coaxial cable, shoot TV
2) Cheaper - after capturing content, you transfer it to Multicast and send it to the network for each TV. Optionally, if you need access control, you can use a paid cloud middleware, so you can cut the packets.
What would I choose?
If you already have a coax network and no access control is required, you can take the signal from the antenna and build a small network using electrical amplifiers/dividers. But it needs to be designed.
If you don’t want to bother too much and there is an already existing IP network, there will be few channels, then I would take an average computer with Linux, stick TV tuners (USB, PCI) to the maximum into it, capture content (ffmpeg, vlc, opencaster) and let it in multicast network.

"Browser or AceStream + VLC."
This is.
I read it briefly and did not see a mention of IPTV
"There is no equipment for set-top boxes that can work with the stream in hardware, all sorts of android whistles are not suitable (even worse, you need to make a proxy for them there)."
As far as I know, the stream can be sent via DLNA directly to smart TV.
Another video stream can be downloaded from tv.sputnik.ru

@opium

there are Russian channels on the satellites that are caught in Tai, I had at least two or three.
