Fraunhofer IIS and Partners Demonstrate End-to-End IP Workflow with MPEG-H Audio and S-ADM Metadata over SMPTE ST 2110-41 at SET Expo 2025 and IBC 2025

Fraunhofer IIS is proud to announce a groundbreaking joint demonstration with its partners BBright, Jünger Audio, Linear Acoustic, and Ateme. Together, they showcase the first complete IP production and broadcasting chain utilizing MPEG-H Audio which transports audio and S-ADM metadata over SMPTE ST 2110-30 and ST 2110-41.

The demonstration will be showcased at two of the world’s most prominent broadcast and media technology trade shows: SET Expo 2025, Latin America’s premier event, taking place from August 18–21, in São Paulo, Brazil, and IBC 2025, Europe’s leading exhibition, held from September 12-15, in Amsterdam, The Netherlands.

Industry First: S-ADM over ST 2110-41 with MPEG-H Audio

The demonstration highlights the seamless interoperability of advanced IP-based production and distribution tools that are purpose-built to support immersive and personalized audio experiences in live broadcast workflows. At its core is the use of SMPTE ST 2110-41 to transport S-ADM (Serial Audio Definition Model) metadata over IP, perfectly synchronized with audio streams encoded into MPEG-H Audio. This ensures complete control of the object-based immersive audio throughout the entire production chain—from live capture and processing to final transmission — without ever leaving the IP domain. For broadcasters operating in SDI-based infrastructures or transitioning gradually to IP, the MPEG-H Audio system provides a reliable SDI transport solution.

Visitors to the Fraunhofer booths will see firsthand how the system switches in real-time between various audio and video formats. It will be shown how the workflow can switch dynamically from traditional stereo and 5.1 audio to immersive, object-based MPEG-H Audio – with time-variant S-ADM metadata seamlessly carried over ST 2110-41 – without interruptions, artifacts or manual intervention. The flawless switching between audio formats even during live operation is a unique capability of MPEG-H Audio and proves its maturity and flexibility for real-world broadcast environments.

Fraunhofer’s MPEG-H Audio system is the first audio technology deployed in regular 4K terrestrial broadcasting and the sole audio system selected for Brazil’s next-generation TV system, DTV+. Its adoption underscores the technology’s readiness for large-scale deployment in modern IP-based broadcast environments. When combined with S-ADM, MPEG-H Audio empowers broadcasters to deliver features such as customizable commentary, dialogue enhancement, and immersive sound —each dynamically customized to individual viewer preferences in real time.

Seamless Integration across the Chain

  • BBright provides their Integrated Playout supporting ST 2110-20/30/31/40/41/43 and enabling seamless transport of uncompressed video, audio, and metadata (incl. MPEG-H S-ADM) in a fully synchronized IP environment.
  • Jünger Audio contributes real-time loudness management as well as metadata authoring and monitoring capabilities for MPEG-H Audio using S-ADM, with native ST 2110-41 support or SDI-based infrastructure.
  • Linear Acoustic integrates real-time monitoring and authoring for MPEG-H Audio and S-ADM, helping broadcasters maintain audio quality and metadata integrity.
  • Ateme ensures reliable and efficient encoding and delivery of MPEG-H Audio and video content, ready for DTV+ (TV 3.0) and other advanced broadcast ecosystems.

Enabling the Future of Personalized IP Broadcasting

“This collaboration marks a significant milestone toward scalable, flexible, and personalized IP broadcasting,” says Yannik Grewe, Senior Engineer for Media Technologies at Fraunhofer IIS. “By combining the strengths of MPEG-H Audio, S-ADM metadata, and ST 2110-41 transport, we enable broadcasters to deliver Next Generation Audio experiences while maintaining open standards and full IP interoperability.”

“This demonstration highlights BBright’s leadership in driving the next generation of IP-based broadcast workflows,” says Guillaume Arthuis, Founder and Managing Director at BBright. “By harnessing the power of SMPTE ST 2110-41 alongside S-ADM and MPEG-H Audio, we’re enabling broadcasters to deliver immersive and personalized audio experiences with unprecedented precision and flexibility. BBright guarantees perfect synchronization of audio, video, and metadata, a new benchmark in delivering higher quality to the end user.”

 

“At Jünger Audio, we’re proud to contribute real-time loudness control and metadata handling that support the full potential of MPEG-H Audio,” adds Roman Rehausen, Product Manager at Jünger Audio. “Our tools ensure that broadcasters can confidently manage complex audio setups in dynamic live environments without sacrificing quality or compliance.”

John Schur, President of Telos Alliance, also emphasized the importance of open standards and interoperability: “This collaboration highlights the real-world value of open standards like S-ADM and ST 2110-41 in enabling next-generation workflows. At Telos Alliance, we’re committed to making immersive audio accessible and manageable—from authoring through transmission—so broadcasters can deliver the best possible experience to every listener.”

Mickael Raulet, Chief Technology Officer of Ateme, highlighted the importance of flexibility in modern broadcast workflows: “At Ateme, we’re proud that our TITAN Live Encoder can support both IP-based and SDI-based workflows, making it a key enabler for broadcasters transitioning to IP infrastructures with ST2110. Its support of MPEG-H Audio, whether over ST 2110-41 with S-ADM or through traditional SDI-based interfaces, ensures reliable, real-time processing from production to delivery — without compromising quality or interoperability.”

The end-to-end solution demonstrated in São Paulo and Amsterdam proves that MPEG-H Audio is ready for large-scale IP workflows and live production scenarios, delivering all the advantages of immersive and interactive sound without compromising on technical efficiency or system flexibility.

Be sure to visit Fraunhofer IIS at their booth #47 at SET Expo 2025 in São Paulo (August 18–21) and booth #8.B80 at IBC 2025 in Amsterdam (September 12–15) to experience this state-of-the-art IP audio workflow in action.
