I am part of a multi-site church in rural Florida. We have been delayed streaming our services from campus to campus for years using hardware based encoders and a small CDN service. We are in the middle of a big push to upgrade and revolutionize our digital presence while additionally providing better quality to remote campuses during Sunday services. We would like to begin live streaming all services, live streaming a mid-week talk show, and incorporating return streams from remote campuses into our production efforts.

Scope:
Dual Stream delivered to all campuses
Channel A = 4k with embedded Audio (Pastor Shot)
Channel B = 1080p (IMAG & Graphics)

Single Stream return from all campuses
Channel C = 1080p with embedded Audio (Campus shots)

Live streaming
Channel A trans-coded from 4k and delivered to Facebook, Periscope, YouTube, etc....

Recording
Pre-production inputs saved to archive for re-edits as space permits
Post Production output of both channels saved to archive

Our Network:
We have a rock-solid network core built with Peplink load-balancing routers with fiber to the premise 100/Meg symmetrical links at all locations for production requirements, and single 10-20 megs DSL links supporting non-production services such as email and guest networks. At the moment we have 80 meg's of throughput from site-to-site through VPN's tunnels running at an average latency of 15ms. We can expand our tunnels out to 900 megs of dedicated throughput from campus to campus with super low latency.

Summary
We would like to re-engineer each of our campuses production booths by inputting all local cameras, sound boards, and Pro Presenter PC's into a vMix machine. With our main campus being the normal broadcast campus and the remotes performing their own worship services but then catching the broadcast and displaying it locally all via NDI and vMix. The remotes would broadcast a local 1080p A/V feed back to the broadcast campus that could be used during service if desired.

Will this work or is it a pipe dream? Your feedback would be greatly appreciated!

@IceStream

Hey thanks for the reply! For me an output format would depend on the location of the vMix machine and the channel that the desired output is coming from. I want to either send the final produced streams out of a PC by de-encoding and displaying on a screen or I want hand it off to another vMix PC via NDI to do the same thing at another location.

I'm still reading the vMix docs and I will download a copy of the software when I have a few pieces of gear assembled to do some testing. So if I'm speaking gibberish I apologize now.

@Tom

Thanks for the link! Yes that is similar to what I'm talking about. Really the jist of it boils down to producing two streams in one location and displaying them on local screens then distributing them around to other locations via NDI over fiber network connections and displaying them there as well.

We are really interested to see if these items are even possible.
* 4k quality on the main feed distributed to all campuses
* Remote campus feedback
* Simultaneous Live streaming to Facebook, Periscope, etc....
