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: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

Im Focus: Explanation for puzzling quantum oscillations has been found

So-called quantum many-body scars allow quantum systems to stay out of equilibrium much longer, explaining experiment | Study published in Nature Physics

Recently, researchers from Harvard and MIT succeeded in trapping a record 53 atoms and individually controlling their quantum state, realizing what is called a...

Im Focus: Dozens of binaries from Milky Way's globular clusters could be detectable by LISA

Next-generation gravitational wave detector in space will complement LIGO on Earth

The historic first detection of gravitational waves from colliding black holes far outside our galaxy opened a new window to understanding the universe. A...

Im Focus: Entangled atoms shine in unison

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...

Im Focus: Computer-Designed Customized Regenerative Heart Valves

Cardiovascular tissue engineering aims to treat heart disease with prostheses that grow and regenerate. Now, researchers from the University of Zurich, the Technical University Eindhoven and the Charité Berlin have successfully implanted regenerative heart valves, designed with the aid of computer simulations, into sheep for the first time.

Producing living tissue or organs based on human cells is one of the main research fields in regenerative medicine. Tissue engineering, which involves growing...
