View Full Version : Guys, How big is a network..... does it have to be in one area?

I can see that a network is all you need to transmit video and audio..... what i wondered is when (or has it happened) will the network extend over the internet or some other device.

Wouldn't it be nice to be able to work with folks in other countries and cities on the same project.

I have a town-wide fiber network that I've connected back to my studio via inexpensive Ubiquiti UniFi products, and NDI works fantastically well. Can't wait to get our TC1 upgrades and try some new things.

I've even been playing with ethernet virtualization layers to push NDI over the internet, it works decently well with low-latency, high-bandwidth links (same ISP, but a few towns over)

There are some solutions.

NDI.cloud will allow for public internet transmission, even if your bandwidth isn't very high, as you can configure the compression between the locations for each link.

A VPN could work in some cases, however you need to have the bandwidth to handle full bandwidth NDI channels.

A dedicated line is probably your best option if you can afford it. I did a test between TD Gardens and NESN where we ran 8 channels of NDI video over a 20 mile fibre connection without issue.

NDI Cloud isn't out of closed-beta yet, unfortunately. We're waiting with baited-breath over here for that one...

Care to expand on this a bit? Inquiring minds...

Until recently trying to get my local network across fiber required two strands: one for send, and one for receive.

Thanks to the incomprehensible voodoo of optics, you just need one strand and wave-division multiplexing now.

For testing purposes, I bought the following:

https://www.ubnt.com/unifi-switching/unifi-switch-16-150w/ (For the remote end)
https://www.ubnt.com/unifi/unifi-ap-ac-pro/ (For remote WiFi)
http://www.fs.com/products/20188.html (For the above switch)
http://www.fs.com/products/20189.html (For your local switch)

Now all you need is a fiber path! Which should already exist if you're like me and have been sending video + audio one-way for remotes previously. It's quite handy having 1gbit local network access, complete with WiFi, anywhere that we have fiber. Makes it much easier to stream, since you're not relying on whatever janky internet is at whatever janky venue.


As far as NDI over the internet with ethernet virtualization... that's a bit more of a work in progress/experiment, but I am using ZeroTier to play around:

https://www.zerotier.com/manual.shtml

It basically creates a second virtual network adapter (that the TriCaster complains about at every boot...) and connects to a virtualized ethernet layer that's routed through the internet. Fancy stuff!

NDI Cloud isn't out of closed-beta yet, unfortunately. We're waiting with baited-breath over here for that one....

Professional users who are serious about wide area NDI and who have the appropriate equipment and connectivity at 2 or more sites and who are prepared to feedback their results are welcome to apply to join the closed beta.
