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 formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
