The problem is the data rate required by the movies – in spite of fast Internet and sat-ellite links. 3-D movies have higher data rate requirements than 2-dimensional movies since at least two images are needed for the spatial representation. This means that a 3-D screen has to show two images – one for the left and one for the right eye.

Researchers at the Fraunhofer Institute for Telecommunications, Heinrich-Hertz-Institut, HHI in Berlin, Germany have already come up with a compression technique for movies in particularly HD quality that squeezes movies while maintaining the quality: the H.264/AVC video format. What H.264/AVC is for HD movies, Multiview Video Coding (MVC) is for 3-D movies. The benefit is reducing the data rate used on the transmission channel while maintaining the same high-definition quality.
Videos on the Internet have to load quickly so that the viewer can watch the movies without interruptions. Thomas Schierl is a scientist at the HHI in Berlin and he explains that »MVC packs the two images needed for the stereoscopic 3-D effect so that the bit rate of the movies is significantly reduced«. These 3-D movies are up to 40 percent smaller. Thomas Schierl and his colleagues are working to establish the MVC codec for television transmission over satellites or the Internet. »New TV sets will start off by only playing 3-D movies from the Blu-Ray disc that is now coming into the third dimension. The next step to bring 3-D into living rooms will be made possible via broadcast or IPTV channels running via DSL or cable.«
You will be able to experience 3-dimensional movies in your living room in future without any 3-D glasses because the MVC format has the technical features to code and compress several views. After all, everybody enjoying the movie with you on the sofa has a different viewing angle. That is why they need a separate view – their »own« 3-D movie – for his or her individual seat. MVC compresses all of these views into one compact file or stream and one receiver, one set-top box decodes this information and passes it on to the television.
It will also be possible to play the MVC-coded movies on older televisions and set-top boxes and Thomas Schierl tells us how: »The first view corresponds to the signal that the existing television can receive and we would hide the second view in the same stream so that only the new receivers can use it. They are invisible to older tele-visions.« That is especially interesting to movie lenders and television stations because they do not have to worry about compatibility. And even mobile radio and mobile phone manufacturers can join the trend towards 3-D with the MVC standard. In the meantime, there are even displays the size of a mobile phone that allow a good 3-D impression.
The experts from the HHI show how the MVC-Codec functions transmitting television via DVB-S2 satellite from September 10-14, 2010 at the IBC in Amsterdam (Hall 8, Stand C81).

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...

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...
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.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
