Finnish network terrestrial operator Digita has turned to virtual media production infrastructure provider Nevion to provide equipment and software for signal transport from its headend to its transmission sites.

Digita is embarking on a project to renew its DVB distribution, moving from transporting signals over SDH, microwave and IP. It also develops and supplies online TV and radio services along with services based on company’s network infrastructure. The project, designed to achieve cost efficiencies and easy regionalisation, required a solution to ensure the reliable transport of signals over IP.

The Nevion solution consists of Virtuoso CP4400 DTT processors deployed at the headend and at the 40 transmission sites. The processors are all managed by Nevion’s VideoIPath management software, which Digita already uses to orchestrate its contribution network.

At each transmission site, the Nevion processors receive protected streams and perform an IP to ASI conversion, ready for transmission and enabling re-use of the first-generation transmitters. In addition to the dual streams received over the IP network, the processors also receive an RF signal from nearby transmission sites. This provides a further level of protection in case the IP link fails completely: Digita can now switch automatically to the RF signal for retransmission on the site.

“Our renewal project needs to bring efficiencies fast, and the Nevion solution meets the criteria,” explained Digita chief operating officer Markus Ala-Hautala. “For example, thanks to the density and functionality of the Nevion Virtuoso CP4400, we were able to achieve our objectives at the headend less the equipment normally needed. In terms of timing, we are looking for a project completion faster than is typical for a DTT project, but Nevion has an excellent track record of rapid delivery.”
