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."

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
