Telos Alliance Partners with Fraunhofer IIS to Reproduce 2019 Eurovision MPEG-H Next-Generation Audio Trial at IBC 2019

At IBC 2019, the The Telos Alliance® works with Fraunhofer IIS and its technology partners to deliver a reproduction of the MPEG-H Next-Generation Audio (NGA) trial that took place at the 2019 Eurovision Song Contest with the European Broadcast Union (EBU).

At IBC 2019, the The Telos Alliance® will be working with Fraunhofer IIS and its technology partners to deliver a reproduction of the MPEG-H Next-Generation Audio (NGA) trial that took place at the 2019 Eurovision Song Contest with the European Broadcast Union (EBU). The demo will take place at the Fraunhofer booth B.80, Hall 8 at the RAI Amsterdam. Together with Solid State Logic (SSL), ATEME, Jünger Audio (now distributed worldwide exclusively by the Telos Alliance), Telos Alliance and Sennheiser, Fraunhofer IIS will showcase an end-to-end transmission chain for MPEG-H Audio content at Europe’s major broadcast industry event. Here, visitors can experience production, transmission, reception, and playback of immersive and interactive sound.

The 2019 Eurovision Song Contest (ESC) in Tel Aviv was produced twice: while millions of viewers all over the world were watching the popular music show in stereo or 5.1 sound, the EBU and its technology partners did another live production of the contest, which was mixed and transmitted using the MPEG-H Audio next-generation audio system. Able to deliver customizable and enveloping sound, this object-based audio technology aims to make the audience at home feel as though they were in the arena themselves. As part of the trial, journalists and EBU members on-site in Tel Aviv were able to experience the MPEG-H Audio‑enhanced show as a DASH internet livestream and as a DVB-compliant live broadcast stream. The latter was also delivered live to broadcasters abroad via the Eurovision FINE network. The “produce once, deliver anywhere” feature is one of the great advantages of the MPEG-H Audio system.

At IBC, Fraunhofer IIS and its partners will re-create the live production process from the ESC: Fraunhofer’s sound engineers will use the System T S500m broadcast console provided by Solid State Logic to produce a 5.1+4H immersive mix of the show, including commentaries in five different languages as audio objects. The mix – audio alongside video – will then be sent to a Telos Alliance Linear Acoustic AMS or a Jünger Audio MMA MPEG-H real-time authoring and monitoring system for live authoring of the MPEG-H metadata and monitoring of various configurations. ATEME’s TITAN UHD broadcast encoder will be used to create a DVB‑compliant broadcast transport stream and, at the same time, DASH and HLS streams for delivery over the internet. At the end of the broadcast chain, the audio streams will be played back on the natively MPEG-H-enabled Sennheiser Ambeo soundbar, which can reproduce the immersive experience captured at the ESC. In addition, there will be a tablet at the Fraunhofer booth that receives the same program via HLS and plays back the immersive content binaurally rendered to headphones.

Thanks to its object-based nature, the MPEG-H Audio System provides immersive sound and enables the viewer to personalize a program’s audio mix, for instance by switching between different languages, adjusting the volume of a commentator, enhancing the dialogue, or choosing from various audio description options. Personalization features like the latter enable broadcasters or providers of video-streaming services to offer more advanced accessibility services. In terms of content delivery and playback, MPEG-H Audio’s universal delivery concept ensures the best sound regardless of the receiving consumer device or listening environment. MPEG-H Audio is standardized in ATSC 3.0, DVB and SBTVD/ISDB-Tb, as well as 3GPP. In South Korea, terrestrial ATSC 3.0 broadcasting with MPEG-H Audio is already on air, making MPEG-H the world’s first commercialized next-generation TV-audio technology.
