 Brainsonic Live might send you graphic assets to use during production, that might includes: 

 

 Backgound slate for multi frame or PiP compositions 

 Full frame video animations including audio that intend to be played for physical audience 

 

 Protocol 

 Our operators are expecting a single stream sent to two different ingest endpoints (main/primary and backup/secondary) 

 The protocol we accept is SRT 1 . SRT is compatible with a majority of encoding software and hardware like VMix , OBS or Tricaster . Brainsonic Live provides two local (closest datacenters) SRT, of type srt-listener , ingest points IPs. Those ingest points are reachable though port 10 000 . A monitoring output (loop out of what you send on port 10 000 ) is provided as well. The final program output can be provided though SRT upon request. 

 1 In some rare cases SRT cannot be used at event location. Even if we do not recommend it, we can accept RTMP ingest following the same encoding specifications.
