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.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...
Scientists from the University of Freiburg and the University of Basel identified a master regulator for bone regeneration. Prasad Shastri, Professor of...
Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
