Fraunhofer DAB ContentServer Ensemble Multiplex Editor

The reliable one-box solution to get your content on-air


The Fraunhofer DAB ContentServer™ R6 is a flexible and highly reliable professional broadcasting solution developed for the digital radio system DAB (Digital Audio Broadcasting).

It combines internal audio encoding, support for remote audio encoders, multimedia data management and multiplex generation. A convenient user-friendly web interface enables configuration and system monitoring via remote access (ContentServer-as-a-Service concept).

The Fraunhofer DAB ContentServer is a complete headend system possessing triple functionality:

  • Internal audio encoding and support for remote audio encoders
  • Multimedia Dataserver
  • DAB Ensemble/Service Multiplex Generator


Application and target audience

The system is typically located in the studio, in a playout center, at the transmitter site, or within dedicated network provider premises – with full remote control for administration and data provision. Whether a community station, a local or regional broadcaster, or a network provider, the system's functionality perfectly complements your needs.

For receiver manufacturers the systems enables close to 100% test coverage for signaling, audio configurations, data services and multiplexing options.


Always up to date

Thanks to continuous development, the ContentServer technology provides broadcasters with the latest standard upgrades and improvements, such as effortless configuration of the Emergency Warning Functionality (EWF).


Perfect match

Various versatile interfaces for audio and content provision pave the way for straightforward integration into studio play-out-systems and complex broadcasters’ and network providers’ environments.

The ContentServer enables the implementation of completely new network structures such as "extended STI-C", wherein centralized service multiplexers feed into regionalized DAB networks.


Keeps you on air - at all times

The ContentServer technology has earned a worldwide reputation for the highest reliability and quality. This is further enhanced by powerful redundancy features (even linking remote sites).


Highlight features at a glance


  • Convenient user-friendly web interface for configuration and system monitoring via remote access (ContentServer-as-a-Service concept).
  • Powerful Monitoring System controlling all system functions including content provision.
  • Internal Audio encoders with AES67-AoIP live audio input (Livewire, Ravenna) or file upload, as well as advanced support for remote audio encoders.
  • Data provision via established protocols such as UECP, FTP/HTTP or XML/JSON RPC API.
  • Modern flexible network structures due to full STI-C support and by enabling completely new network structures where all common programs are encoded and scheduled by a central service multiplexer and simultaneously fed to multiple regional ensemble multiplexers ("extended STI-C").
  • This core feature-set is further expanded with new redundancy provision such as hardware redundancy, audio cross redundancy, and local fallback audio in case of failing (remote) audio provision. Redundancy even works across remote sites.


The Fraunhofer DAB ContentServer™ R6 is available in several editions (option packages). These editions provide different features to accomplish typical use case scenarios. All editions can be extended by additional features.

The system as a complete package, including hardware and specific customer support services, is available from Fraunhofer’s OEM partners.

Fraunhofer Prize 2016: Digital Radio for the World

Digital radio makes spherics and crackling interference in radio broadcast a thing of the past. New technologies from Fraunhofer IIS make it possible for digital radio to replace analogue short and medium wave broadcasting around the world. Alexander Zink, Martin Speitel, Max Neuendorf and their entire development team received the Fraunhofer Prizes 2016 as recognition of their efforts in developing the foundations of digital radio and its continuation to market roll-out.
