Drive multi TV (running kodi) by DLNA



Hi, my friend has built a fast food, he’s using 3 TV 32″ to show clients the menu, offers, and so on, using an USB stick for each TV, he is bored to take the staircase, go up to all tv, remove the stick, update it and place it again, he would use an automatic system using network, ha has a free WIndows PC for that.

He has dream to show separate contents separately by a playlist from a PC to each TV, were is possible to indicate medias (lovely if they can be images and videos) and time (first image will stay 10 seconds, the second photo 15 seconds, the third video till the end, then loop again to first image, etc); I don’t mean that the next TV has to show the “extend image” of the first TV and so on, just different indipendent content.
The TV are connected by ethernet cable under the same LAN, I’ve installed Kodi, activated all services and noticed I can send by DLNA files from my phone, so I guessing there is a software for Windows able to push in the same way, but to 3 different TV, maybe I have to run 3 istances of the same program?

Which program can I use to push DLNA to Kodi?

There is another way to obtain that, streaming, but this require to encode real time a video and send stream to TV,  there are 3 TV, encoding 3 times is really a waste of CPU and quality, with risk the TV quits from streaming and needed to join it again manually.
Instead, DLNA doesn’t encode, and stimulate TV to receive something new, is something went wrong before it will fix itself.
Thank you for your suggestions
