How to massively distribute a file to TVs?

Question

Computer networks

In general, there is a task - in the N-th number of buildings there is the N-th number of TV sets on which the video file is spinning. Each time, pulling out a flash drive from each and filling it with a new one is long and dreary.
How to optimize, preferably with minimal cash costs? Some kind of Raspberry PI comes to mind, which will take files from the server, but for every TV on the Pi - it does not sound very optimal). Are there any best practices?

Answer 1

I suggest looking towards iptv. If your TV allows you to install applications, then the task will come down to installing an iptv application on a TV with a built-in playlist with 1 channel. The channel can be streamed with something like vlc.
Again, it depends on how much your hypothetical N is. If we are talking about 10 panels, and even on different platforms, well, run with a flash drive, if there we are talking about 30-40-50 identical TVs, then it’s already easier and the game is worth the candle .

Answer 2

There is such a thing as DLNA , and many household devices can work with it. There are also analogues, such as miracast, apple airplay, etc., you can go to them using links from the wiki.
If suddenly some of the TVs are not smart enough, there are a variety of "TV whistles" and set-top boxes.

You take the most unusual household DVD player and the cheapest shielded cable. You hang N + 1 "tulips" on the wire. Well, you understand...
