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: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...

Im Focus: Basel researchers succeed in cultivating cartilage from stem cells

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.

Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...

Im Focus: The Future of Ultrafast Solid-State Physics

In an article that appears in the journal “Review of Modern Physics”, researchers at the Laboratory for Attosecond Physics (LAP) assess the current state of the field of ultrafast physics and consider its implications for future technologies.

Physicists can now control light in both time and space with hitherto unimagined precision. This is particularly true for the ability to generate ultrashort...

Im Focus: Stronger evidence for a weaker Atlantic overturning

The Atlantic overturning – one of Earth’s most important heat transport systems, pumping warm water northwards and cold water southwards – is weaker today than any time before in more than 1000 years. Sea surface temperature data analysis provides new evidence that this major ocean circulation has slowed down by roughly 15 percent since the middle of the 20th century, according to a study published in the highly renowned journal Nature by an international team of scientists. Human-made climate change is a prime suspect for these worrying observations.

“We detected a specific pattern of ocean cooling south of Greenland and unusual warming off the US coast – which is highly characteristic for a slowdown of the...
