Coming to a cinema near you - courtesy of ESA

25.06.2002


We`ve got digital television. Next comes digital cinema. Thanks to ESA, cinema-goers in five European countries will be able to get an early taste of the new technology later this summer. As part of an ESA-funded project, ten cinemas in Austria, Germany, Italy, Spain and the UK will be screening movies transmitted and played digitally rather than by the conventional analogue method.



The advantage to the cinema-goer should be no blemishes on the moving image and greater and consistent clarity. Conventional film suffers from degradation, which increases with the number of times it is played. Movies stored digitally on the cinema`s computer hard disc can be played indefinitely with no loss of quality.

When digital cinema really takes off, film and distribution companies will also see a big advantage, as they will no longer need to make and deliver thousands of bulky reels of film to cinemas worldwide. Distribution will involve no more than relaying the movie via satellite from the distributor`s to individual cinema`s computers.


"Cinema is the last medium to go digital because the amount of information you need to handle is enormous if you are to have the same quality of image we`re used to seeing with analogue 35mm film," says Francesco Feliciani who coordinates the digital cinema project from ESTEC. The information contained in a TV image is far less as the screen is so small. The same amount of information displayed on a cinema-size screen would result in a very grainy, poor quality image.

Digital cinema is now becoming a reality, thanks to technological advances in digital compression, storage, delivery and digital projectors. ESA is supporting the take up of this new technology under its ARTES programme, which aims to encourage European and Canadian industry to exploit new ways of using satellite communications. The Agency is collaborating with two project teams which are working on different aspects of producing and transmitting files containing about 60 Gbytes or about 100 CDs- worth of information, enough for one feature length movie.

Cast4All, a Belgian company, has developed a "multicast management platform" which allows the distributor to select and send a film digitally via satellite to specified receivers and to monitor the reception status of each site to ensure reliable delivery. Elsacom, an Italian company, is leading a team including UCI, Screen-Digest and Cinecittà, which is preparing and will be running the pilot service for five months in 10 European cinemas this summer. As well as showing feature movies, the pilot will also demonstrate other possible uses of the digital cinema. These include being able to tailor adverts to local audiences and show alternative content such as live events which can be transmitted directly to cinemas via satellite, just like live TV. The advent of digital cinema opens up new and varied uses for our movie theatres.

Im Focus: The fastest light-driven current source

Controlling electronic current is essential to modern electronics, as data and signals are transferred by streams of electrons which are controlled at high speed. Demands on transmission speeds are also increasing as technology develops. Scientists from the Chair of Laser Physics and the Chair of Applied Physics at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in switching on a current with a desired direction in graphene using a single laser pulse within a femtosecond ¬¬ – a femtosecond corresponds to the millionth part of a billionth of a second. This is more than a thousand times faster compared to the most efficient transistors today.

Graphene is up to the job

Im Focus: LaserTAB: More efficient and precise contacts thanks to human-robot collaboration

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.

Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...
