Cebit 2017: Jump Into Your Favorite Movie Scenes With Multi-View Video Streaming

13.03.2017

With modern transmission technology, so much more is possible than has made it into our private living rooms so far. Multi-View Video Streaming for instance lets users move into a recorded scene and view it from different perspectives.

Possible applications range from consumer electronics, computer games and virtual worlds to realistic video conferences and autonomous driving. Until now, there was no overall functioning system for this technology. Now computer scientists from Saarland University will be presenting their solution at this year’s Cebit computer fair.

Thanks to advancements in camera technology, a single scene can be captured from different perspectives with several cameras at once. This opens up entirely new fields of application, especially for home electronics: “Say you are watching a detective story, and you can hear the suspect talking in the room next door, off-screen. Then you could use this new technology to simply switch perspectives and look around the corner,” says Tobias Lange, PhD student at the Saarland University.

Together with Thorsten Herfet, Chair of the Telecommunications Lab at Saarland University, Tobias Lange is researching multi-view video streaming at the Intel Visual Computing Institute. The individual components of this technology already work by themselves, but so far there has been no complete integrated system. This is what the two Saarland computer scientists and their colleagues are trying to change. The potential applications for multi-view video streaming are abundant.

Multi-view video streams could not only revolutionize the entertainment industry, but also the workplace, with true-to-life video conferencing, for instance. “This technology might even be useful if several autonomous cars are driving in convoy. Or how else would the car at the rear be able to access images from the car in front?,” asks Lange.

Presently there are still some challenges that have to be addressed in order to fully implement this vision. The greatest difficulty: Network technology has not developed as rapidly as recording technology has. Not only do the videos need to be recorded with several cameras, they also have to be encoded into a set of data packets and stored in a transmission buffer on the video server.

From there, they will find their way over the Internet to viewers’ computers. There the data needs to be unpacked in time and played back in such a way that viewers can switch their perspective without encountering any image errors. “The data rate is ludicrous. Even now we need such a high bandwidth that most contemporary Internet connections would be overloaded,” Lange explains. The calculations themselves are also highly complex.

The Saarbrücken researchers are tackling this challenge by improving the entire production process step by step. For streaming, they use special computational methods to minimize the delay until it is so small as to be nearly unobservable. And for encoding and decoding the data in an acceptable time span, they rely on a distributed approach. Each camera has a mini-computer of its own attached to it.

The researchers have also developed a new method for computing the images that can be viewed from different perspectives almost in real-time. With these incremental improvements, they have created a comprehensive working system. “Only a few solutions exist,” says Lange. Hence, he is unsure whether that is sufficient to make the technology marketable.

“Maybe our research partner Intel will take over. They will be looking at our results in their entirety,” says Lange. The researchers are now presenting their completed system at the Cebit computer fair from March 20 to 24 in Hannover (Hall 6, Stand E28).

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
