Genereal questions about syncing with BrightSign players.

Hi,

first I have to admit, that I am totally new to BrightSign Players and haven't really worked with BA.

I am currently working on a piece of software using open frameworks. The software is controlling DMX lights over ArtNet, combined with a sequencing software. I want to sync the sequencer with a video running on a BrightSign player. For my tests I got handed a XD1030. It is running a single video file and I ran wireshark to see how it is communicating over Ethernet. I found the pre- and ply-sync packets and am able to start my sequencer synchronized with those.

Now I am wondering, if there are any options to get sync information (maybe timecode or current frame) while the video is playing. Can a slave device request this information during play or does the sync only get broadcasted at the start/end?

What happens exactly, if I plug in a slave, while the master is already running a long video? Does the slave have to wait until the video starts over?

Thank you very much,

 

Ben

    Hi,

    Our sync isn't timecode based. We synchronize the videos when they start playing, and again each time the video restarts.

    Benjamin,

    My answer (above) was related to the original (legacy) sync option.

    If you're using Enhanced Synchronization or BrightWall, the sync isn't just done when the video starts but throughout playback using the sync manager. That's why you can restart a slave unit, and it'll pickup right where the other units are, and not wait till the video restarts. See this faq:

    Maybe not the best option, but I have done in the past, is to put time code on the Right Track and Audio on the left track, then use the 1/8" audio jack on the player, splitting the timecode to off to a lighting console, and the audio went to a mixer/amp/speakers.  The video (in this case) basically looped all day long, and the lighting console would use the timecode track to do all the lighting cues for the display to match the video.

    Again may not be exactly what you want to do, but may give you options to consider.
