MPEG-4 Audio-Visual Solutions One-Stop at Fraunhofer IIS

22.06.2004


High-quality video transmission with multi-channel sound through DSL connections finally becomes reality thanks to an up to now unmatched efficiency in audio and video compression. The revolutionary new multimedia technology can be licensed one-stop at Fraunhofer IIS.

MPEG-4 Advanced Video Coding AVC allows screen-filling video in good quality at data rates of less than one megabit per second. High Efficiency Advanced Audio Coding Surround (HE-AAC Surround) is the ideal audio companion for MPEG-4 AVC, since it only needs 64 kbits/s for coding high- quality 5.1 channel sound. Therefore, the video codec can use almost the full data rate for bringing a brilliant screen picture to life.

Engineers of the department ”Multimedia Realtime Systems” in Erlangen have combined the latest audio codec HE-AAC Surround of Fraunhofer Institute for Integrated Circuits IIS with the most efficient video codec MPEG-4 AVC of Fraunhofer Institute for Telecommunications, Heinrich-Hertz-Institut, HHI. This way high-quality video streaming with 5.1 channel sound becomes possible even through DSL connections with standard PCs. Furthermore, Fraunhofer IIS is developing optimized hardware implementations for example for set-top boxes, mobile radio units or MP3 video players.



The Fraunhofer HHI and the Fraunhofer IIS are internationally leading research labs in the field of MPEG-4 Audio and MPEG-4 Video Coding and have more than 15 years of experience in creating innovative audio and video solutions for hard- and software.

Fraunhofer IIS developed the popular MP3 format, played a crucial role in standardizing MPEG-2/4 AAC and contributes to the development of the MPEG-4 audio standard. Fraunhofer HHI is leading in the field of developing and standardizing new video compression schemes. Consequently it provided the vice-chairman of Joint Video Team (JVT), a joint standardization group of ISO/MPEG and ITU-T, which specified the new video coding standard MPEG-4 AVC.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
