We've just started playing around with synchronization and we're curious about how it works. We notice that without sync, the videos on two BrightSign units soon go significantly out of step, even after a short while. Both units are triggered by a udp message, so the videos do start at the same time.
We notice that when sync is added, the master sends a sync message on a transition, then waits for a response. I guess this is how it tees up the videos.
My question is does the sync only happen at the transition, or does it occur while a video is being played?
If I want to sync several BrightSigns, I guess I should have the master broadcast the udp packet. How does the master manage all the responses from the slave? Does it sync up on the first received response?
Thanks for any help you can give.
