5.1 Surround Sound for FM HD Radio at NAB 2005

13.04.2005


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.


Steve Church, Telos Systems Founder & CEO, says “We will show that genuine, non-matrix surround is practical and doable today. There is no need to compromise.” Further, “We expect that people who experience the demo will be not only impressed with the quality of the audio itself, but surprised at how simple and low-cost it can be to implement.”

The surround encoder / decoder system has been designed by Fraunhofer IIS and Agere Systems. It is part of the reference model of the currently ongoing MPEG Spatial Audio standardization process. The key to the surround system is that all the pieces of the audio that go to the surround channels are present in the two stereo channels created manually by an artistic downmix, while the spatial information is transmitted in the ancillary data channel of the bit stream.

Harald Popp, Head of the Fraunhofer IIS Multimedia Realtime Systems Department notes, “With the help of our long-time partner Telos Systems and our huge experience in audio and video coding, we can prove the high quality of the upcoming MPEG Spatial Audio standard already implemented in real-life broadcast.”

Church concludes, with regard to the Acura exhibit, “The car is the perfect environment for the surround experience, and since that’s where a lot of radio listening happens, we wanted to show what surround can bring to radio’s party in the real world.”

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
