Fraunhofer IIS-A setting the pace in transactional watermarking, unveils optimized MP3 bitstream

17.08.2000


Fraunhofer Institute for Integrated Circuits, Applied Electronics IIS,the world leader in audio compression technology and Home of MP3 unveilsadvanced signal
processing technology: Advanced Watermarking technologyhelps content providers to keep track of their content and protect theirintellectual property.

Fraunhofer Bitstream Watermarking technologybundles Fraunhofer´s robust watermarking scheme with their famous suiteof high-performance audio coders by allowing direct embedding of watermarkdata (such as digital signatures) into coded music content. In this way,material can easily be personalized to any particular customer and tracedback in case of illegal proliferation. This is an important step for themusic industries and the secure digital distribution of audio files.Direct embedding of digital watermarks into coded bitstreams reduces timeand cost efforts for the companies while preserving optimum signal quality.

While Fraunhofer IIS-A had already presented the world´s firstbitstream watermarking scheme for MPEG audio coders at the AES trade showin Paris, February of 2000 (based on the MPEG-2 Advanced Audio Codingscheme), more brand new technology will be released at the upcoming AESconvention in Los Angeles, September 22-25 2000: MP3 support in the newbitstream watermarking technology now allows seamless and efficient dataembedding for the de-facto audio coding
standard on the Internet."The new bitstream watermarking systems were designed with two goalsin mind: Achieving the best possible performance of the combined codec/watermarksystem and maintaining the renowned Fraunhofer audio quality" saidChristian Neubauer, in lead of the development effort. "Much efforthas been put into rigorous listening tests and optimization of thepsychoacoustic models, taking advantage of Fraunhofer´s long-standingcodec expertise."



The Fraunhofer Institute for IntegratedCircuits, Applied Electronics IIS-A, develops microelectronic circuits,devices, and systems up to complete industrial solutions.
Fields ofapplications are information and communications technology, imaging sensortechnology, image processing, X-ray and medical technology.

Theinstitute is also the leading research laboratory in the area of audiocoding. Since the start of its audio coding work more than 10 years ago,Fraunhofer IIS-A has
participated actively in the development of audiocompression algorithms. Major parts of MPEG-1 Layer-3 (MP3), the mostpopular audio format on the Internet, have
been devised at itsheadquarters in Erlangen, Germany. The MPEG-2 Advanced Audio Coding (AAC)algorithm, which is the most efficient coding algorithm currentlyavailable, was also developed in cooperation with experts from FraunhoferIIS-A. AAC offers a 16 fold data reduction while maintaining CD quality.

Inaddition to audio coding technology, Fraunhofer IIS-A is also working ondata-hiding technologies for use in watermarking and fingerprintingsystems. Fraunhofer
IIS-A is active in international efforts to developmethods to technically manage and protect intellectual property, includingthe MPEG-4 work on Intellectual Property
Management & Protection (IPMP),the Audio Engineering Society´s (AES) activities on Internet AudioDelivery Systems and the Secure Digital Music Initiative (SDMI)
beinginitiated by the Recording Industry Association of America (RIAA), theRecording Industry Association of Japan (RIAJ) and the InternationalFederation of the
Phonographic Industries (IFPI).

Im Focus: The taming of the light screw

DESY and MPSD scientists create high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might find intriguing applications in petahertz electronics and for spectroscopic studies of novel quantum materials.

The nonlinear process of high-order harmonic generation (HHG) in gases is one of the cornerstones of attosecond science (an attosecond is a billionth of a...

Im Focus: Magnetic micro-boats

Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.

The magnetic properties of a material control how this material responds to the presence of a magnetic field. Iron oxide is the main component of rust but also...

Im Focus: Self-healing coating made of corn starch makes small scratches disappear through heat

Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.

Superficial micro-scratches on the car body or on other high-gloss surfaces are harmless, but annoying. Especially in the luxury segment such surfaces are...

Im Focus: Stellar cartography

The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.

A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...

Im Focus: Heading towards a tsunami of light

Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.

"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
