Getting To The Root of Remote Production

It's rare that a vegetable can be used as a metaphor in the world of broadcast technology. Sure, we all love a turnip, a potato, a nice bunch of carrots, but it's rare we encounter them at an event about audio networking.

At Tonmeistertagung, Calrec's Head of Technology Patrick Warrington introduced the networking onion as part of his talk on Wide Area Neworking and Remote Production. Think of it as an enticing carrot to get the broadcast donkey's juices flowing, if that's not too much of a stock metaphor.

The audio onion is Patrick's analogy to help us understand the different layers in broadcast audio transportation from acquisition to mixing to transportation to broadcast.

Now before I make you sick by overfeeding you with any more vegetable related puns I shall get to the point in hand. Since the dawn of television there have been live broadcasts and the majority of these are produced on location. This is still the main method of broadcasting live events from large format sporting events such as the World Snooker Championships to smaller more intimate soirées such as a Royal Wedding. At such events there is always an outside broadcast unit on site.

Now this kind of facility requires a great deal of time and know-how to set up. But how can this be reduced so we can be more efficient and produce better results I hear you cry? Well, once the signal is captured, via a microphone for example, it could be injected straight into the core of the onion using AoIP. This means that there could be a shift away from using an OB unit as all signals could be directed straight back to the studio anywhere around the world. BUT, and it is a big but, and I cannot lie, there are many arguments as to how and why this is achieved that this paper so elegantly explains.

If you want to find out what the latest thinking is with considerably less vegetable puns then the paper, which was today incorporated into the Tonmeister journal, is available here.
