For the first time Fraunhofer Institute for Integrated Circuits IIS in Erlangen, Germany, presents a combination of MPEG-4 Advanced Video Coding (AVC/H.264) and MPEG-4 High Efficiency Advanced Audio Coding (HE-AAC) for high quality, real time movie playback on ARM®-based Personal Digital Assistants (PDAs).
MPEG-4 AVC and MPEG-4 HE-AAC are the most advanced video and audio codecs within the MPEG-4 multimedia standard. At ARM Developers Conference, Fraunhofer IIS now introduces a combination of the two codecs to mobile devices, guaranteeing best audio and video quality at very low data rates. This is realized by optimized implementations for embedded processors.
With the MPEG-4 AVC Baseline Profile, optimized for Wireless MMX™ on Intel XScale PXA27x processors, a video resolution of up to QVGA (320x240 pixels) at 25 frames per second can be achieved. Together with MPEG-4 HE-AAC, which allows excellent audio quality for stereo content at bit rates of 48 kbit/s and below, high-quality movie playback on PDAs or other mobile devices finally turns into reality.

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
