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."

Optical quantum computers can revolutionize computer technology. A team of researchers led by scientists from Münster University and KIT now succeeded in putting a quantum optical experimental set-up onto a chip. In doing so, they have met one of the requirements for making it possible to use photonic circuits for optical quantum computers.
Optical quantum computers are what people are pinning their hopes on for tomorrow’s computer technology – whether for tap-proof data encryption, ultrafast...
The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.
“Augmented-reality” and “wearables” have become terms we encounter almost daily. Both can make daily life a little simpler and provide valuable assistance for...
With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.
Elpasolite is a glassy, transparent, shiny and soft mineral with a cubic crystal structure. First discovered in El Paso County (Colorado, USA), it can also be...
For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.
Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...
