How to implement a service for video downloading files and displaying them on the site?

Question

Programming

Hello!
What's on:
===
There are several machines (PC Windows/Linux) on which video materials from customers are shown.
We edit videos from customers, upload them to a flash drive, go around all PCs and change files.
There are 4G modems on the PC, which do not work at high speed, the traffic is not cheap.
All this takes a very long time.
What I would like:
===
All this can be done remotely, with the ability to add / remove videos from the pool, so that, accordingly, with each change and adding a new video, do not make unnecessary movements.
Accordingly, there should be a web service that users go to, upload their videos for 15-20 seconds, and after verification (moderation), they appear on the corresponding PCs.
I just don't even know how to fully describe the problem.
How to organize the delivery and broadcast of these clips on a PC? Service development does not cause problems.
Videos that are uploaded in large size, they need to be encoded, compressed or something else to show on the screen / site.
For example, there are 5 videos, so they should spin one by one endlessly and naturally without a minute upload)
Also, the video is shown on the site on average every 5 minutes, for example, how not to load them all the time.
PS Maybe there are already services or techniques for solving this problem.
Thanks in advance!

If the channel is weak and even pays for traffic, then you can forget about live video broadcasting. It is better to open the video directory on the server via FTP or Samba. And on the terminals, do rsync of the remote directory to the local directory from where the broadcast is coming from. This will be as economical as possible in terms of traffic (as far as possible) and any problems with the network can only slow down the synchronization in the worst case, while the broadcast will continue uninterrupted.
Transcoding of video uploaded by users is, of course, necessary. But this is a separate issue.
