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.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
