Television audio of the future - customizable and in 3D

09.09.2015

The next generation of Ultra High Definition televisions (UHDTV) offers not only crystal-clear images, but also perfect sound. At the IBC trade show (September 11-15 in Amsterdam), Fraunhofer researchers are presenting a TV audio system based on the recently published MPEG-H 3D Audio standard, which lays the groundwork for the television audio of the future. Besides offering immersive audio capability, this new technology allows viewers to customize the audio playback of the television or other devices.

Imagine you are watching your favorite sports team in your home theater system: Not only are you right in the middle of the action thanks to 3D sound , you can even choose to listen to the commentator of the home or away team, or to engulf yourself completely in the stadium atmosphere with its cheering fan crowds .


The MPEG-H 3D Audio standard will allow television viewers to individually customize their TV audio by changing the volume of dialog and background noise elements independently of one another.

Thanks to the new MPEG-H 3D Audio standard, viewers will be able to individually adjust volume settings for elements such as different commentators without affecting the volume of other elements, such as the stadium atmosphere.

“Users themselves are able to customize the audio playback on their home TV as they desire, whereas previously such changes could be made only by the TV station itself. This technology is known as object-based audio transmission,” says Matthias Rose of the Fraunhofer Institute for Integrated Circuits IIS in Erlangen, Germany, which led the development of this technology.

When equipped with the right speaker configuration, this new technology also allows for a true 3D listening experience at home. “This really makes the viewer feel a lot more like they’re a part of the action,” says Rose.

The MPEG-H 3D Audio standard offers a number of ways to transmit audio content. One way is to transmit the individual audio channels directly, as is currently commonplace, and another is to deliver them as scene-based audio signals (Higher-Order Ambisonics). Additionally, the individual elements of the audio signal can be transmitted as audio objects.

“In practice, we expect audio signals in the future to be comprised of a channel- or scene-based description of music and effects, the sound bed, and several audio objects that contain primarily speech elements,” says Rose.

This technology isn’t expected to be available to consumers for a few more years. It will first be standardized for general broadcast use before it can be used by television stations and installed in devices by manufacturers.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
