Robust audio delivery

Optimized for live broadcast radio

Fast re-tuning response time (low zapping delay)

Optional surround broadcasting using MPEG Surround

For broadcasters and receiver manufacturers, Fraunhofer IIS offers DAB+ encoders and decoders as well as professional broadcast server systems.

HE-AAC v2 encoders and decoders optimized for the DAB+ transport layer are available, including super-framing capability and comprehensive PAD support. Fraunhofer IIS provides these codecs for various PC platforms, a wide range of fixed-point and floating-point DSPs, and embedded processors. All have been successfully tested for compatibility with other DAB+ implementations. These codecs can also be obtained in combination with the highly optimized multi-channel extension MPEG Surround.
