##### Content

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<sup>1</sup>. SRT is compatible with a majority of encoding software and hardware like [VMix](https://www.vmix.com/help23/index.htm?SRT.html), [OBS](https://obsproject.com/kb/srt-protocol-streaming-guide#:~:text=Stream%20with%20SRT,-Go%20to%20Settings&text=In%20the%20Service%20dropdown%2C%20select,enter%20anything%20for%20the%20key.) or [Tricaster](https://support.newtek.com/hc/en-us/article_attachments/1260802200430).  
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.

*<sup>1</sup> 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.*
