Fraunhofer IIS, Telos, Omnia, Axia, Broadcast Electronics and Bose participate in world-premiere live demon-stration of non-matrixed 5.1 Surround Sound for FM HD Radio.
Fraunhofer Institute for Integrated Circuits IIS and its partners join to present at the 2005 NAB show a first live demonstration. The end-to-end demonstration will involve the complete HD Radio broadcasting chain comprising the studio, on-air broadcasting and automotive digital radio receivers. The original multi-channel material will be mixed in discrete 5.1 surround at the Axia booth and then passed over a wireless link to the Telos / Omnia booth to be encoded for surround by Fraunhofer IIS Spatial Audio software. As a next step the encoded material is processed for FM transmission and broadcast on an HD Radio channel using a Broadcast Electronics HD Radio Exciter.
A Visteon car radio modified by Fraunhofer IIS will receive and decode the over-the-air signal for 5.1 surround at the Telos booth. The visitor will also be able to audition HD Radio surround audio in an in-car environment, courtesy of a prototype Bose 5.1 Cabin Surround Sound system at the MPEG Pavilon.

3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
