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: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Im Focus: An energy-efficient way to stay warm: Sew high-tech heating patches to your clothes

Personal patches could reduce energy waste in buildings, Rutgers-led study says

What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...

Im Focus: Topological material switched off and on for the first time

Key advance for future topological transistors

Over the last decade, there has been much excitement about the discovery, recognised by the Nobel Prize in Physics only two years ago, that there are two types...
