As high-spec home entertainment goes wireless

08.04.2005


A high performance, low-cost wireless home connectivity solution for applications requiring the multi-streaming of high-quality video has been demonstrated by a team of EU-funded researchers.

The technology and system, developed by IST programme-funded ULTRAWAVES project supports high performance, low-cost wireless home connectivity solution for applications requiring the multi-streaming of high-quality video as wireless connectivity between Set Top Boxes, DVD and TV, PC projectors.

The project demonstrated a wireless audio/video solution using ultra-wideband (UWB) technology, which transmits about 100Mbits per second, 10 to 100 times faster than traditional wireless systems.



“The significance of our work is that we demonstrated the capability to transmit a high bit rate application using UWB technology,” explains project coordinator Rafi Zack, Wisair, Israel. “An important potential application is the wireless high-quality video home environment that uses UWB infrastructure instead of the fat cable from the DVD player to the TV, or from DVD to the PC projector used in home cinema applications.”

The project used HDTV (MPEG2 Main Profile at High Level) and split it into three DVD streams. The three streams were issued over the UWB link from the transmitter to three receivers. Each receiver was connected to the PC projector. The result was a projection of HDTV stream built from three synchronised video streams. This is significant for home entertainment applications because most projectors cannot support HDTV. For example, the professional IMAX films use five projectors.

“The evaluation showed that UWB technology is very efficient for video-based applications,” he says. “The high bit rate capability enables the carrying of high quality video.”

ULTRAWAVES overcame an important obstacle to creating wireless environments – cost. The UWB transmits very low signal power (less than 200µW), which makes it attractive in terms of power saving. Because the technology may be implemented in a relatively small silicon size, the solution may be used in a wide range of consumer electronics.

Several partners in the ULTRAWAVES project, which ended in October 2004, are participating in a new project, which takes the results further. PULSERS is an industry-led initiative focusing on exploring, developing and exploiting the potential of ultra-wideband radio technology, and contributing towards standardisation issues.

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...
