At the IBC trade show, Fraunhofer IIS is debuting the latest version (R7) of its professional ContentServer technology for DAB+ digital radio and DRM, available in products from Fraunhofer OEM partners. The ContentServer R7 has many new features such as additional interfaces for IP-based audio streaming sources, automatic normalisation and loudness monitoring (based on Fraunhofer Sonamic technology) and full CAP compliance for automatic processing of EWF (Emergency Warning Functionality) messages.

The demo station will show how the ContentServer generates multiplexes that are then played back via a Fraunhofer DAB+/DRM MultimediaPlayer radio application. In addition, the DAB+ and DRM standardised data applications Journaline and EWF will be shown as part of the ContentServer R7 demo. Furthermore, the hybrid radio solution of Fraunhofer IIS will be presented: this shows all components of a modern SDR-based radio system for the reception of analogue and digital radio services combined with the possibilities of internet streaming. By continuously searching for the best reception option, hybrid radio enables users to enjoy uninterrupted listening while on the move and also offers them an easy way to listen to favourite regional programmes outside the respective broadcast areas. Especially for in-car listening with multiple audio zones and additional digital information services, several independent reception units can be active simultaneously on one radio platform.

MPEG-H Audio: Personalized and immersive sound for broadcast and streaming

© A. Popov –

The MPEG-H audio system enables immersive and interactive customisable sound with enhanced accessibility features such as dialogue enhancement and audio description. With MPEG-H, next-generation audio is already a reality, as the system has been on the air 24/7 in South Korea since the UHDTV system was launched there in May 2017 and is also used for streaming: The new immersive 360 Reality Audio music streaming services are based on MPEG-H audio. The immersive music tracks, available from providers such as Amazon Music HD, Deezer, and TIDAL, can be played on mobile devices (with headphones), soundbars, smart speakers and also in the car.

Listen to a 3D audio experience that perfectly matches your preferences. With MPEG-H, you can choose from presets or make your own settings. For example, it is now possible to switch between different languages, adjust the volume of a sports commentator, enhance the dialogue and choose from different audio description options. All these features contribute to the pristine sound that listeners expect from quality services today.

Fraunhofer DIALOG+ in Broadcasting: Deep-Learning-Based Dialogue Enhancement

User complaints about hard to understand dialogues due to loud background sounds are common in broadcasting. Object-based audio, e.g., MPEG-H Audio solves this problem by providing a user-adjustable speech level. While object-based audio is gaining momentum, transitioning to it requires time and effort. Also, lots of content exists, produced and archived outside the object-based workflows.

To address this, Fraunhofer IIS has developed a deep-learning solution called Dialog+, capable of enabling speech level personalization also for content with only the final audio tracks available. On public field tests conducted together with WDR and BR, starting September 2020, we proved the capabilities of Dialog+. As part of one of these tests, a survey with more than 2,000 participants showed that 90% of the people above 60 years old have problems in understanding speech in TV often or very often. Overall, 83% of the participants liked the possibility to switch to Dialog+, including those who do not normally struggle with speech intelligibility. Dialog+ introduces a clear benefit for the audience, filling the gap between object-based broadcasting and traditionally produced material.

xHE-AAC: The audio codec of choice for adaptive audio and video streaming and digital radio

Say goodbye to interrupted or buffering audio and video streams: the latest addition to the AAC codec family offers maximum coding efficiency, with a stereo bitrate range from 12 kbit/s to 500 kbit/s and higher. Combined with seamless bitrate adjustment using DASH and HLS, as well as mandatory MPEG-D DRC volume and dynamic range adjustment, xHE-AAC is the ideal solution for adaptive audio and video streaming services - whether movies, music, audiobooks or podcasts - as well as digital radio. xHE-AAC decoding is natively supported in Android OS 9 and higher, Fire OS 7 and iOS 13. Fraunhofer also offers a web-based testing service that developers and manufacturers can use to check their implementations of the xHE-AAC® audio codec for compliance with MPEG standards. The free service can be used to test both encoders and decoders. It is exclusively available at and can be used after registration at Fraunhofer IIS.

At the Fraunhofer IBC booth, visitors can experience the benefits of xHE-AAC in video and internet radio streaming applications.


LC3/LC3plus: High-quality audio for the entire communication ecosystem

© cristalov -

The new LC3/LC3plus audio codec was jointly developed by Ericsson and Fraunhofer IIS to address the drawbacks of today's wireless communication platforms. The low complexity of the codec meets the requirements of wireless communication platforms such as Bluetooth, DECT and VoIP terminals. By reducing the required bit rate by about 50 per cent compared to older codecs, LC3 and LC3plus enable energy-saving services that allow for longer battery life or the development of smaller products. Thanks to the flexible codec design, applications are not limited to voice services, but can also be extended to high-quality music streaming. At the same time, the codec operates with low coding delay, low computational complexity and small memory requirements. Learn more about LC3/LC3plus at our booth and experience the quality of a phone call using LC3plus.




JPEG XS - Low Latency Codec for Video over IP Transmission in Production Quality!

JPEG XS stands for extra speed and extra small. The new ISO mezzanine codec standard co-developed by the Fraunhofer Institute for Integrated Circuits enables interoperability and allows an easy and cost effective integration into IP based infrastructure.

As an ultra low-latency lightweight image coding system, JPEG XS offers visually lossless quality with compression ratios up to 10:1. It also supports resolution up to 8K and features a frame rate from 24 to 120fps.

Whether Virtual Reality, gaming, in-house or broadcast and digital cinema workflows, the  JPEG XS mezzanine codec can be applied where today uncompressed video is used.

Licensing available for software and SDKs.

IMF Studio - Creation, Playback and Validation of Interoperable Master Packages

We offer the new software suite IMF Studio for the creation, playback and quality assurance of IMPs, which has been derived from our well-known software suite easyDCP for the creation of Digital Cinema Packages (DCPs). Due to a very flexible subscription licensing model, IMF Studio enables users to create complex workflows in local and cloud-based environments.

The Interoperable Master Format (IMF) is a universal, file-based solution for the exchange of high-quality image and sound data as well as subtitles in a common format. Broadcasters, film producers and streaming services use IMF packages for the data exchange during production and post-production as well as for the delivery of content. Furthermore, an IMP can serve as master and source package for creating various distribution formats.
