Hear the future of television audio featured by the MPEG-H Audio Alliance

At this year’s SMPTE Annual Technical Conference & Exhibition, visitors to the Fraunhofer IIS booth 108 will be able to experience the progress being made in building a new audio system for future TV standards based on the recently completed open MPEG-H Audio standard.

To make MPEG-H Audio a reality, the three industry leaders Fraunhofer IIS, Qualcomm Technologies and Technicolor have formed the MPEG-H Audio Alliance. Each one contributes key technical elements as well as long-standing expertise within their market segments. The combined experience and broad-market presence represented by these three companies has not only been critical in developing MPEG-H, but also provides the foundation for successfully bringing exciting new audio features to market.

The system includes object-based audio that allows viewers to adjust the sound mix to their preferences, boosting hard-to-understand dialogue or creating a “home team“-mix of sports broadcasts. Immersive sound may be carried using a traditional channel-based approach or using Higher-Order Ambisonics technology.

Fraunhofer IIS will feature a real-time hardware prototype with the ability to encode audio for live broadcasts from stereo up to 3D sound in 7.1+4 H format with additional tracks for interactive objects including commentary in several languages, ambient sound or sound effects.

Fraunhofer’s real-time system is comprised of:

  • real-time encoder for contribution from outside broadcasts to the studio, where a professional decoder recovers the uncompressed audio for further editing and mixing;
  • real-time encoder for emission to consumers - over the Internet for new media use or for trials of upcoming over-the-air broadcast systems such as ATSC 3.0;
  • professional decoder used to monitor the emission encoder's output.
