As I scrolled through Twitter this evening this tweet jumped out at me. What got my attention was that BBC Autumnwatch were using SRT to stream a number of camera feeds from their location in Norfolk back to their base in Bristol. 

The Aviwest BeOnAIR can stream via SRT to broadcasters and strangely enough, my last article mentioning SRT is the most viewed on this website.

I reached out to the author of this tweet, an engineer working on Autumnwatch with a couple of questions about SRT and its uptake in broadcast.

We used SRT because we had great fibre lines into the location. We knew the network itself is stable, so we chose SRT for a lower latency etc.

In terms of SRT uptake, broadcasters are starting to adopt, but in small capacity overall. Autumnwatch is one of the first productions to go SRT/RIST IP encoding for the main paths.

With network infrastructure only growing, and a move to IP occurring anyway – SMPTE 2110 uptake especially – it only makes sense for SRT to start to appear.

This got me thinking about how the BeOnAIR could have been used within this workflow. One of the key choices for SRT seems to have been a stable fibre line from their fixed location. Using BeOnAIR in the field or knowing Autumnwatch from the middle of a field would mean the unit would be reliant on mobile data.

Fortunately with up to six bonded connections the Aviwest AIR220 unit would certainly be able to provide a stable connection, lets have a closer look at that workflow.

Broadcast via SRT in Three easy steps

  1. Connect your camera via SDI or HDMI to the AIR220 encoder. 
  2. Open your StreamHub cloud and set your SRT destination.
  3. Go live.
