Question

DLNA

Good afternoon,
how to broadcast photos and videos to several TVs but that there was no constant stream .. (do not load the Internet, because the TVs are located in different cities)
that is, added files, uploaded to all TV or some device, server .. and that's all hanging came from there .. but as little as possible the human factor

Answer 1

In your case, you need to put a caching device near each TV (a router with support for usb disks / flash drives or memory cards is enough), all network TVs can play from home NAS, so ordinary home routers with ftp configured are enough so that you can upload (your scripts) your files and TVs could play them on them.
If your TV does not know how to network, then buy a memory card with wifi access and insert it through a usb card reader into the TV, then set up access to the flash drive through a router (it’s better to configure vpn from all routers of networks where TVs are connected to your management server)
