Movies in Your Pocket

20.10.2004


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.


Harald Popp, head of the Multimedia Realtime Systems department at Fraunhofer IIS, is enthusiastic when he thinks about the possibilities the new development offers: "There are millions of portable devices like PDAs out there. Every single one can become a small movie theatre which you carry around in your pocket. No more annoying hours of waiting for delayed planes: Just turn on your PDA and enjoy a comedy or an action movie."

Im Focus: The fastest light-driven current source

Controlling electronic current is essential to modern electronics, as data and signals are transferred by streams of electrons which are controlled at high speed. Demands on transmission speeds are also increasing as technology develops. Scientists from the Chair of Laser Physics and the Chair of Applied Physics at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in switching on a current with a desired direction in graphene using a single laser pulse within a femtosecond ¬¬ – a femtosecond corresponds to the millionth part of a billionth of a second. This is more than a thousand times faster compared to the most efficient transistors today.

Graphene is up to the job

Im Focus: LaserTAB: More efficient and precise contacts thanks to human-robot collaboration

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.

Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Tiny lasers from a gallery of whispers

New technique promises tunable laser devices

Whispering gallery mode (WGM) resonators are used to make tiny micro-lasers, sensors, switches, routers and other devices. These tiny structures rely on a...
