Synology DS213j how to play video synchronously on 2-3 TVs?

Question

Synology

Hello. There is Synology DS213j, the video shows everything is ok. But the task arose on 2-3 TVs to show the same thing, of course, at startup, there is a lag in the stream in turn, the first shows for 10 seconds, and the second is just the beginning.
Who has come across a similar one, how can you form a stream for broadcasting, with rotation, so that the same fragment is shown on all TVs synchronously?
Those. put video clips in a folder and all TVs play the stream synchronously?
I'm using DSM 5.0-4458 Update 2
