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.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
