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.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
