More about IZT Digital Broadcasting

Regarding digital broadcasting IZT generally delivers equipment for the two use-cases broadcast infrastructures and receiver development. Typical applications are the operation of DAB and DRM networks and testing of DAB/DRM receivers.

IZT’s software-based solutions for digital radio infrastructures are perfectly suited for the operation in virtualized environments. Based on matured technology and permanent evolution, IZT delivers flexible and scalable systems to fit requirements and customer needs.

High reliability, enhanced redundancy concepts, minimized down-times and easy migration to new hardware or virtualization enable future-proof solutions. The underlying Fraunhofer software technology stands for highest audio quality and long-term expertise in digital radio systems.

The completely software-based ContentServer technology enables operation of DAB multiplexers as virtual machines in IT data centers.

For the development of radio receivers, the IZT Digital Broadcasting equipment is perfectly completed by the IZT S1000 / S1010 for the generation of test signals. The setups support DAB and DRM standards. This includes implementation and testing of enhanced data services such as SPI/EPG, TPEG and combined receiver testing with FM, DAB, DRM, and much more other digital broadcasting standards including service following (alternative frequencies).
