PORTLAND, OR,�November�30, 2016���As the world�s largest�international broadcaster, BBC World Service broadcasts radio and TV services worldwide in more than 30 languages. For the United States Presidential�election�on November 8, the BBC World Service established a temporary�production and distribution facility within its Washington DC bureau. The�BBC World Service�production staff�utilized�Dante�networking from�Audinate�to manage and deliver live coverage to radio audiences worldwide�over the�BBC World Service, NPR partner stations,�BBC Radio 4 and BBC�5 Live�networks (as well as BBC�local radio in the UK)�� reaching�as many as 250 million listeners over a 12-hour period.

In a clear�sign�of�the�shift to digital,�the use of Dante by the�BBC World Service�contrasted with�their use of�a legacy contribution and distribution architecture for live�US presidential�election coverage four years ago. The transition to�audio-over-IP using Audinate�s Dante networking technology massively improved�efficiency across all business and technical aspects.

�It�s a big difference when you remove the labor of running hundreds of copper analog audio circuits,� said Matthew Page, engineering manager, BBC. �Four years ago, we had�three broadcast studios sharing contribution sources, all connected by copper multicores, analog talkbacks and analog audio routers to switch mix-minus feeds.�That�was a lot of equipment and heavy cable, all of which had to be connected on site. This year, we configured�most of the equipment in London, then connected it on site�with readily available and inexpensive network cabling. We saved�hundreds of�hours of�rigging and testing on location, and thousands of British Pounds overall. It was lightweight enough to�mostly�carry on the plane, which reduced our shipping costs by�80 percent.�

The complete system featured 17 Dante-enabled devices�including�128x128�intercom/IFB, AES & analog�I/O�and broadcast mixing consoles,�all enabling the distributed�routing�of�hundreds of�circuits�with built-in redundancy�for�immediate failover to a secondary network.

Inside the facility,�the Dante network�supported connectivity between the temporary studio in the basement-level conference room, and smaller studios in the main bureau on the eighth floor. Dante was also used to route�over thirty�incoming contribution feeds, with associated mix-minus,�from�various�IP and ISDN codecs. The�AoIP network�provided further efficiency,�allowing�simple�off-the-shelf�fiber�Ethernet�connectivity between�the�nine�floors�to be used.

The flexibility�of the Dante network proved�to be�especially useful for communications across the bureau and election coverage production.

�Once the core infrastructure is in place, it�s very�easy�to scale. Adding a new studio with access to all the same sources is�almost�as�easy�as�plugging�a few extra network cables�between an�Ethernet�switch�and�another Dante-enabled mixer and intercom panel,� said Page. �We had Dante connectivity between our talkback panels in the temporary facility, and�our�intercom�matrix in the main bureau.�Dante�s�connectivity�allowed us to place the talkback panels wherever we wanted, which simplified communication between�production staff and�all contribution circuits, presenters and guests.�

Dante�s�very low latency provided an additional benefit to presenters and guests, allowing each to�listen to�any�live feed�available on the�audio�network�on�headphones in one ear and�studio�output in�the other�without any program delay.�
