No frontiers: ushering in a new era of conferencing technology

08.09.2009
Poor image and sound quality is encountered all too frequently in the world of video and telephone conferencing, but powerful compression technologies are set to consign these problems to the past – even in the humble living room.

At this year’s IFA international consumer electronics exhibition in Berlin (September 4 to 9) Fraunhofer researchers will demonstrate the power and flexibility of these new technologies by holding games sessions in which players compete against each other via the Internet. This is one of the many new developments to be presented by four Fraunhofer Institutes at the TecWatch technology forum in Hall 5.3.

The TV program Jeux Sans Frontières was highly successful in the 1960s and 70s. Several teams from different European countries competed against each other to demonstrate their prowess in various games of skill. Today, in the digital age, the program’s English title, Games Without Frontiers, takes on a different connotation. Internet games bring people together from different countries, but in most cases the participants are not in direct contact in terms of seeing and hearing each other. The EU-funded project Together Anywhere, Together Anytime TA2 aims to change this situation. Thirteen partners from seven countries have taken on the task of developing new technologies and concepts for simplifying and improving group communication via the Internet, e.g. by creating a situation in which participants who are a long distance from each other appear to be sitting around the same table. In our modern mobile world, people are moving all the time to different cities and countries for study- or work-related reasons. Many would appreciate the opportunity to enjoy a game with their family or friends in the evening as if they were still at home.

One of the research partners in the project is the Fraunhofer Institute for Integrated Circuits IIS in Erlangen. The researchers there have the job of ensuring that the sound will be of high and consistent quality. To this end, they have developed the Audio Communication Engine, which consists of reciprocally-tuned components that vastly improve the sound quality and clarity of video and telephone conferences compared with present systems. The key component in providing excellent sound is the MPEG Enhanced Low Delay AAC audio codec, which ensures low-delay hi-fi quality even at low bit-rates. An echo control eliminates troublesome echo so that users do not have to wear a headset and can move around the room freely. Sophisticated signal processing, which extends from enhancement of the microphone signals through to multi-channel loudspeaker reproduction, removes the barrier of distance between friends without incurring great installation expense. Moreover, the Fraunhofer scientists have already turned their attention to actual implementation by designing the technology for integration in TV sets, set-top boxes and hi-fi

systems.

Visitors to the IFA international consumer electronics exhibition in Berlin will be able to experience the system’s superb picture and sound quality – and even play games such as Memory, Battleships and Sorry! – at TecWatch technology forum in Hall 5.3.

Im Focus: Superconducting vortices quantize ordinary metal

Russian researchers together with their French colleagues discovered that a genuine feature of superconductors -- quantum Abrikosov vortices of supercurrent -- can also exist in an ordinary nonsuperconducting metal put into contact with a superconductor. The observation of these vortices provides direct evidence of induced quantum coherence. The pioneering experimental observation was supported by a first-ever numerical model that describes the induced vortices in finer detail.

These fundamental results, published in the journal Nature Communications, enable a better understanding and description of the processes occurring at the...

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
