Nowtilus & Serverside.ai win HbbTV Award
for “Best Scale-Up Project" with Fraunhofer & Discovery


At the HbbTV Symposium and Awards 2021 that took place in Paris, an independent jury of international industry experts selected the winners among 27 submissions from 9 countries.

Nowtilus wins the 2021 HbbTV Award as Best Scale-Up Project for their Serverside.ai Addressable TV with Dynamic Ad-Substitution (DAS). This resulted from intense research and development efforts and investment during the last 12 months allowing us to create an outstanding targeted full-break ad substitution. The solution is respecting the needs and requirements of our customer Discovery Networks for full compatibility across the European HbbTV device footprint and by supporting underlying DVB-TA and HbbTV-TA standards and specifications.
