Fraunhofer Institute for Integrated Circuits IIS introduces its novel Spatial Audio Coding technology, which enables 5.1 Surround Sound for Digital Audio Broadcasting DAB. The Bayerische Rundfunk (BR) and Bayern Digital Radio (BDR) broadcast the first 5.1 program over DAB live on "Bayern 4 Klassik" during the Medientage event in Munich. A DAB surround receiver prototype was developed and integrated in a passenger car by the Panasonic Automotive Systems Europe GmbH.
Spatial Audio Coding SAC is a new technology developed by Fraunhofer IIS in collaboration with Agere Systems. This generic surround extension can be associated with almost any perceptual audio codec while remaining fully backward compatible to stereo or even mono broadcasting. The achieved audio quality is very close to a fully discrete surround system despite the fact that the surround image is represented by only 16kbit/s of additional data. The DAB implementation is based on a combination of the MPEG Layer-2 codec with the surround information embedded as ancillary data into the bitstream. A conventional DAB receiver will simply ignore the surround information whereas DAB surround receivers reproduce the full multi-channel sound. On the part of the broadcasting station, the SAC based system only requires an SAC compatible audio encoder.
During the Medientage event in Munich, the first live broadcast of 5.1 surround sound over DAB is presented at the Bayern Digital Radio GmbH booth Y1 as well as the Panasonic Automotive Systems Europe booth Y2. The transmission of the Program Associated Data PAD is still possible while using Spatial Audio Coding technology.

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...
