Robust and Reliable Broadcast Grade Internet STL's
Broadcast Internet STL's need to be high quality, low latency and reliable. This is usually done one of the following three ways.
1. PEER TO PEER WITH RENDEZVOUS SERVER
2. PEER TO PEER WITH TURN SERVER
3. PEER TO PEER WITH FIXED IP (BARIX)
The most popular economical way for our clients is to use the first way, peer to peer with the FREE rendezvous server. But there are some situations where this does not work 100%, for example in temporary outside broadcast use and other special uses.
Also maybe clients want full 'plug n play' regardless of cost, just something that will work on delivery, anywhere when it is connected. We get that! and this is the reason we have tried to cover all digital STL scenarios.
PEER TO PEER WITH RENDEZVOUS SERVER
This is our favourite method, it is simple, robust and zero cost forever once the equipment has been purchased from us. It only has one negative point, the receiver / decoder router needs to be ported. Other to that it is perfect using highly efficient low latency Opus encoding. So, it's not 100% 'plug n play', but it is very close. 90% of our clients can and are successful in porting their transmission site routers to enable this method to function perfectly. We can also give you a lot support in this.
PEER TO PEER WITH TURN SERVER
This method is pretty much the same as the previous method with the Rendezvous Server, but it is the extra special version! if it was a car, it would be the GT model or AWD.
This works exactly the same as the Rendezvous Server, it will try and do everything possible to make the connection peer to peer between the sender / encoder router and the the receiver / decoder router, but in this case you don't need to port the receiver / decoder router, the Turn Server will make every attempt to do this for you automatically. If it fails and cannot make the connection peer to peer, it will reroute heavy audio data stream via the Turn Server and establish the connection. this can happen on some mobile networks or with routers that have an unusual firewall or NAT.
This method is truly 'plug n play' anywhere. Meaning you should be able to turn up on the front line in Ukraine and if you can find any internet connection, it will send the audio back in high quality Opus encoding and pretty close to real-time with low latency
The only negative on this is server data cost of 10 USD / month.
PEER TO PEER WITH BARIX
This is how we would do it with Barix Ice Instreamer. The Ice-cast protocol uses TCP and not UDP, so it is always going to have a few seconds latency. In addition the AAC+ codec has much more latency than the Opus codec, so this adds even more total latency. Also the AAC+ codec needs a higher bit rate for the same audio quality if you are on metered connection, then this is another headache.
To set this up peer to peer the send / encoder (Instreamer) router needs to be ported. This can be done if you know the router password and have a little patience. But this router also needs to have a fixed IP. This is normally obtained from the internet service provider. Prices can vary, but they are typically 10 USD / month.
The standard Instreamer can stream RTP/UDP but unfortunately it only supports MP3 and not Opus or even AAC+, so the quality vs bitrate is very poor.
