MPEG-H Audio at IBC 2015

Interactivity – Immersive sound – Universal delivery: The future of TV audio featured by the MPEG-H Audio Alliance

MPEG-H Audio offers viewers the ability to turn up or down particular audio elements in a program - such as dialogue or sound effects - as they prefer.

The audio system developed by the MPEG-H Audio Alliance of Fraunhofer, Technicolor, and Qualcomm allows broadcasters and streaming services to deliver the future of TV audio at comparably low bit rates and in a cost-effective manner. It is based on the MPEG-H Audio standard and is being evaluated for the new ATSC 3.0 TV broadcast standard for the U.S.

The system is designed to work with today's broadcast equipment. It includes object-based and immersive audio that allows viewers to adjust the sound mix to their preferences and improves the realism of sound. Furthermore it will tailor playback to sound best on a range of devices and environments, providing "universal delivery".

What to expect at IBC 2015

Fraunhofer IIS will show real-time encoding and decoding as well as authoring and rendering of MPEG-H audio. The combined audio/video content will be broadcast to a Technicolor consumer set-top box for playback so that visitors can experience the new interactive and immersive features of MPEG-H audio in a living room environment. The demo will cover a wide range of audio content formats, e.g. stereo, 5.1, 5.1 + 4H, 7.1 + 4H and HOA (Higher Order Ambisonics).

To enable broadcasters to take advantage of all the features of MPEG-Audio, new products have been developed, some of which will be on display at the Fraunhofer booth:

  • The Jünger Audio MPEG-H Audio Monitoring and Authoring Units adapts today's 5.1 consoles for immersive audio production and allows operations to audition MPEG-H Audio in the plant as it will be reproduced on viewer's devices.
  • Real-time encoders and decoders that include MPEG-H Audio, supporting all phases of content delivery including contribution, distribution and emission using AVC video in our demonstrations.
  • Selective loudness leveling available from Alliance partners such as Jünger Audio prevents the undesirable concatenation of loudness processing or leveling at network, affiliate, and MVPD points in the signal chain.
