MWC 2010: Breakthrough for mobile television

12.02.2010
Long Term Evolution, the new mobile telecommunications standard, will revolutionize mobile Internet. High transmission rates will soon be possible on mobile devices.

For this purpose Fraunhofer researchers at HHI Berlin developed the cross-layer design SVC over LTE – a coding method that offers HD films in real-time in the appropriate format for cell phones or netbooks. The experts are presenting their solution in a live demonstration at the Mobile World Congress in Barcelona in Hall 2, Booth E41.

Clumsy page layouts, slow page load times of podcasts and videos: Today’s mobile surfing on the Internet can be really a hassle. The available bandwidths on mobile phone networks vary widely, due to the number and mobility of the users, the location within the mobile network cell, or the capacity of the terminal. Particularly in bandwidth-intensive services, like video streaming, transmissions are frequently subject to disconnections, gaps or interruptions.

The mobile telecommunications standard of tomorrow – Long Term Evolution, or LTE for short – will change everything. It has a higher performance capacity than UMTS, and reaches download speeds being comparable to landline-based DSL broadband network. Not only e-mails and Internet traffic, particularly videos and mobile television benefit from LTE as the breakthrough for mobile Internet technology.

The "Multicore SVC Real-time Encoder" encodes a basic version of the video, the base layer, and places several enhancement layers in the SVC bit stream next to the base layer in one single processing step. Partial decoding of the scalable bit stream allows graceful degradation and bit rate, format and power adaptation. LTE can now use a higher error protection to transmit the base layer. Thus, each mobile terminal can always decode the basic version of the video stream and guarantees the transmission of video services everywhere and for every given point of time. Under good network conditions, the mobile user can benefit from premium video quality by decoding additional enhancement layers.

The cross-layer design SVC over LTE, an invention by the scientists at the Fraunhofer Institute for Telecommunications, Heinrich Hertz Institute HHI in Berlin, are making high-resolution video encoding over LTE a reality. "SVC over LTE" responds to variable user demands with great flexibility, and enables for the first time seamless adaptive communication without annoying disruptions. Current postage stamp-sized, hiccupping video streams will be a thing of the past.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
