IP-based solution replaces microwave links for transport of TV, FM and DAB signals
Nevion, an award-winning provider of virtualized media production solutions, announced that Saarländischer Rundfunk (SR), the public radio and television broadcaster serving the German state of Saarland, has selected and deployed Nevion media nodes and IP-routers to connect their headend to their main transmitter sites. The deployment provides a more flexible, cost effective and secure solution than the existing STM-1 microwave systems.
As part of its roll-out of DVB-T2, SR decided to move the transport of signals to its main transmission sites to IP technology running on fiber. After careful evaluation, SR chose Nevion and local partner LOGIC Media to deliver the solution it required.

Nevion TVG425 media nodes now provide DVB-T2 ASI to IP conversion and vice-versa, with full dual path redundancy for protection. Nevion VS 906 media nodes provide a similar conversion for AES and E1 to IP. Nevion eMerge IP switches provide IP aggregation and routing for all IP flows, which include two DVB-T2 multiplexes, four FM programs, an ETI data stream for DAB and various E1 channels, as well as IT in-house applications.
The legacy microwave connection remains in place as a back-up solution, in the unlikely event the new fiber connection should fail. For this purpose, the IP signal is converted to STM-1 on a port of the eMerge switches.

Markus Kirst, engineer at SR, explains: “Nevion and LOGIC Media have a wealth of experience in IP technology, from simple point-to-point to large distributed networks, so they were the obvious partners for this project. The solution was delivered on time, and performs exactly as we expected.”
Fil Soares, Vice President of Sales Europe at Nevion, concludes: “We are delighted to add SR to our long list of customers who have chosen to deploy IP technology, and we are proud to deliver a solution that met the requirements in collaboration with our partner LOGIC Media.”
