At NAB Show 2017 Fraunhofer HHI presents the latest developments in 360 degree video and Virtual Reality (VR).
You find the following highlights at Fraunhofer Booth 6110, South Upper Hall, and Booth N1216VR, Virtual & Augmented Reality Pavilion:

New 360 degree OmniCam-360 with closed sphere and live stitching
Fraunhofer HHI’s OmniCam-360 is a worldwide unique system for recording high-resolution video panoramas. For instance sport or musical events can be experi-enced in an Ultra High Definition panorama up to 360 degrees. The latest devel-opment makes it possible to provide this UHD panoramic content for Virtual Reali-ty (VR) glasses. Thanks to the real-time solution of Fraunhofer HHI, the ten single camera segments are smoothly composed to an UHD video that can be transmit-ted to VR glasses so that the spectator is able to enjoy a truly immersive experi-ence. At NAB the new very light version of the OmniCam-360 with closed sphere will be shown.
3D Human Body Reconstruction
At the Fraunhofer Heinrich Hertz Institute, the 3D human body reconstruction technology captures real persons with multiple cameras at the same time and creates naturally moving dynamic 3D models. Afterwards, they can be integrated in computer graphics virtual worlds or real scenes. The human 3D models can be manipulated to change their viewing direction, movements and animation. This technology is being used for the first time in cooperation with UFA GmbH in the course of a joint test production for the immersive film “GATEWAY TO INFINITY” as a volumetric virtual reality experience. Results will be shown at NAB.
Tile Based DASH Streaming for Virtual Reality with HEVC
Only high resolution content can give a sense of immersion in VR video applica-tions, but the large amount of data poses a challenge to common transport sys-tems and decoders. Tile based DASH streaming with lightweight HEVC Tile Ag-gregation allows to easily adapt on-the-fly the 360° video data stream to the cur-rent user viewport. This technology allows reducing throughput and decoder re-quirements significantly without complex transcoding.
Interactive Live Streaming of 10K Video Panoramas with HEVC
At the Fraunhofer booth, the OmniCam-360 captures live high-quality 360-degree panorama video. The video is transmitted from the OmniCam-360 to an UHDTV. Any section (region of interest – ROI) of the panorama can be selected with a re-mote control and scaled to UHD. The user may scroll horizontally trough the pano-rama and he may also zoom out, in order to show the complete panorama on the screen. For the use of VR glasses an UHD receiver decodes the HEVC panorama video and the full panorama is downsampled to UHD and re-encoded.
HEVC Live Statmux
The latest generation of Fraunhofer HHI’s H.265/MPEG-HEVC software encoding technology is enabling HEVC live encoding of 10-bit 60Hz UHD video with High Dynamic Range (HDR) and Wide Color Gamut (WCG).
With the Statmux Fraunhofer HHI developed a new component of its HEVC Live Encoder Software Developer Kit (SDK). The technology enables an analysis of the video material and an allocation of the total bitrate to different video encoders depending on the complexity of the content. Thus, significant bitrate savings as well as quality improvement of the video content of single channels can be gained while the available bandwidth is used most efficiently.

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...
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...
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...
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....
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...
