MPEG-H is the world's most advanced TV audio system and the only one on the air 24/7 in continuous broadcast. It is a mature technology fully implemented in consumer products today. Low-complexity software implementations, patent licensing, and decoder and product certification are available to manufacturers.
Fraunhofer's MPEG-H development and support team 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 many DSP and SOC 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 below.
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.
For real-time implementations on embedded processor cores, SOCs, 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:
PC-based SDKs and applications for Windows, Linux and Mac OS X are available as source or object code.
To indicate to consumers that products implementing the MPEG-H Audio System will interoperate correctly, Fraunhofer operates the MPEG-H Audio System trademark program. The program is optional and administered without charge by Fraunhofer. The program is designed to initially cover consumer end-user products for TV broadcast, for example TV sets, soundbars or set-top boxes.
Fraunhofer operates the program without any fees or charges. Manufacturers are responsible for testing fees charged by independent authorized test centers for end-product testing.
While no testing program can guarantee to catch every bug, the program has been designed to thoroughly test the user interfaces, input and output connections, audio controls and processing, and basic MPEG-H decoding functions of a product. This ensures connection issues with other trademarked components are minimized.
The MPEG-H Trademark is an indication to consumers that a product design has passed third-party testing to verify MPEG-H functions as it should, so they may purchase it with the confidence that it will work with other MPEG-H devices and deliver programming with advanced audio features.
The program includes test bitstreams, test fixtures, worksheets, and procedures already designed to verify system features are implemented correctly, saving the time and effort to develop internal test programs. Advanced features of the MPEG-H system, including those outside the audio decoder, are tested as well.
The program test suites verify that products include the features and profiles that broadcasters use in their programming, preventing consumer disappointment when their device does not support viewing programs with additional audio elements.
The program does not constrain the look and feel of a manufacturer's user interfaces, or demand a high level of reproduction quality. Manufacturers are free to select appearance and performance points that match their market requirements. Products are never inspected by Fraunhofer, only by independent authorized test centers. Manufacturers may also use the test materials for internal testing and development.
Fraunhofer operates the MPEG-H Audio System trademark program, but does not test products. Authorized test centers selected by Fraunhofer will perform product testing according to the program specifications. Manufacturers are free to choose any test center. Testing arrangements between a manufacturer and a test center are independent of Fraunhofer.
The following companies have been licensed to provide Decoder Test Certificates for decoder components or software that have been tested for compliance with the MPEG-H Audio System trademark program. End-product manufacturers may use these decoder components or software and accompanying certificate or test their own decoder implementations as a prerequisite to end-product testing.
The following companies have been licensed to provide end-product designs that have been tested for compliance with the MPEG-H Audio System trademark program. End-product manufacturers may offer these products under their own brand with the MPEG-H trademark by joining the trademark program.
The following companies have been licensed to manufacture consumer products that have been tested for compliance with the MPEG-H Audio System trademark program.
