ATSC-techsupport@dmt.fraunhofer.org will put you in immediate contact with our U.S.-based team of veteran broadcast engineers, A1's, and sound designers who are ready to assist you in learning about MPEG-H and how it can be used in your facilities and productions.

Fraunhofer has experience in planning and producing live broadcasts in full immersive sound with many interactive elements and we can explain the creative considerations of next-generation audio production for sports.

We also offer assistance in adapting facilities for MPEG-H production and distribution, from engineers who were central to the standardization and implementation of the original ATSC system as well as the design of ATSC 3.0. Some of the concerns in moving to next-generation audio are discussed in our facilities paper, where we explain our simplified four-stage process for moving to advanced sound.

Since MPEG-H is distributed as uncompressed audio within the TV plant, monitoring and editing is easy. There are no frame delays to compensate for and the system may be operated without maintaining the tight A/V timing required in a Dolby E system. Additionally, MPEG-H offers true frame accuracy without the trade-offs of locking audio coding frames to video. MPEG-H also allows the use of the same codec for contribution, distribution or emission purposes just by adjusting the bitrate appropriately.

mpeg-h-techsupport@dmt.fraunhofer.org allows you to speak directly and immediately to our software developers and engineers.

MPEG-H encoder and decoder software is available or under development for several embedded platforms as well as traditional X86 computers and mobile operating systems.

Fraunhofer IIS has provided software and integration support to software developers and device manufacturers since its invention of MP3. We have many customers who are entering their third decade of using our software products. Our software is usually licensed to consumer manufacturers for a one-time fee with no per-unit royalties. Note that patent licensing is entirely separate from software licensing. Information on the patent licensing program is available here.

For real-time implementations on embedded processor cores and DSPs, Core Design Kits (CDKs) are available. They are optimized for devices with limited resources in terms of memory and computational power, such as TV sets, set-top boxes, sound bars, AV receivers, or smartphones. The CDKs are mainly written in plain C programming language for maximum portability and optionally include processor specific optimization in subroutines. The CDKs can be directly compiled for a wide range of 16-bit or 32-bit embedded processors and DSPs, thus offering a common, easily maintainable code base for a variety of target platforms. Code can be licensed in source code form or as object code libraries for various compiler tool chains:

  • ARM based processors
  • Cadence/Tensilica HiFi Audio DSP
  • Texas Instruments C6x DSP Family
  • Analog Devices Sharc DSP Family
  • MIPS-based processors
  • Source code for other platforms

PC-based SDKs and applications for Windows, Linux and Mac OS X are available as source or object code.

Fraunhofer IIS supplies optimized audio encoder and decoder mobile libraries for use with Android-based systems, the Apple iOS Software Development Kit (SDK), and other mobile platforms. For example, Fraunhofer supplies the FDK library that is used in the Android OS for encoding and decoding AAC. It includes surround sound up to 7.1 channels and full loudness metadata support. Over one billion Android users now use the AAC framework provided by the FDK.
