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 .
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.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
