The Fraunhofer Heinrich Hertz Institute will present current and never before shown video technology innovations at IBC 2018. At the Fraunhofer joint booth 8.B80, Fraunhofer HHI researchers will show a demonstrator for consistent VR 360 degree live video streaming with a resolution bigger than 4K and a total latency of under 6 seconds. Moreover, the current version of the HEVC successor Versatile Video Coding (VVC) will be presented to the public for the first time as well as recent developments of 3D Human Body Reconstruction for Vir-tual and Augmented Reality, which is the foundation for the volumetric video studio that opened at film park Potsdam-Babelsberg in June 2018.
Live end to end streaming of VR360 degree 10K video with MPEG-OMAF and HEVC tiles
Streaming high-quality VR360 degree video with resolutions up to 10K x 4K consumes large amounts of bandwidth. Moreover, the encoded video requires decoding capabilities beyond 4K video at the receiving side, e.g. on VR glasses with a mobile phone. Fully standardized tile-based streaming solves these issues by spatially segmenting the 360 degree video into tiles.
Each tile is encoded with HEVC at the original high-definition and an additional low-definition resolution. The new MPEG-OMAF standard allows to package the HEVC tile streams in a way that the receiver, e.g. VR glasses or a TV screen, can request the high-definition tiles for the user's viewport and low-definition tiles for the areas out of sight. The tiles are aggregated at the end device into a single HEVC compliant video stream and decoded with a legacy hardware video decoder on the end device.
At IBC 2018, Fraunhofer HHI showcases for the first time in Europe a demonstrator for consistent VR 360 degree live video streaming with a resolution bigger than 4K. This includes high-resolution 360 degree video capturing and live rendering by the Fraunhofer HHI Omnicam-360 with a resolution of 10K x 4K, HEVC tile-based live encoding with the Fraunhofer HHI HEVC encoder, packaging according to the MPEG-OMAF viewport-dependent media profile and high-quality playback on VR glasses and TV screens.
Versatile Video Coding (VVC), compression beyond HEVC
Compressed video data are growing at a faster rate than ever before. Already today, video data make up by far the highest percentage of bits on the Internet and in mobile data traffic. This demonstrates the need for even more efficient compression, which goes beyond the current High Efficiency Video Coding Standard (HEVC).
In order to master this demanding challenge, the ITU-T Video Coding Expert Group (VCEG) and the ISO/IEC Moving Pictures Expert Group (MPEG) have already started working together in the Joint Video Experts Team (JVET). In April 2018, Fraunhofer HHI and other leading technology companies successfully proposed cutting edge coding technology with compression capability beyond HEVC. This marked the starting point of the Versatile Video Coding (VVC) standardization activity. The VVC standard is expected to provide 50% bit rate reduction over HEVC when finalized by 2020.
At IBC 2018, Fraunhofer HHI showcases the most recent version of the VVC reference codec (VTM-2.0). This early version already demonstrates significant coding efficiency improvements over HEVC for content ranging from standard High Definition (HD) to High Dynamic Range Ultra-HD content.
Volumetric Video Production and Workflow
Fraunhofer Heinrich Hertz Institute and VoluCap GmbH present a novel and innovative capture studio as well as a processing workflow for high quality volumetric video productions targeting future VR/AR media productions.
In June 2018, the first volumetric video studio on European mainland was opened at the Filmpark Potsdam-Babelsberg, Germany. Real persons are captured with multiple high-resolution cameras in a professional studio environment. A powerful processing suite automatically generates naturally moving dynamic 3D models, which can be integrated in AR/VR applications. The system supports diffuse or synchronized scenic lighting from any direction, automatic keying, and flexible multi-camera arrangement.

Graphene enables clock rates in the terahertz range
10.09.2018 | Helmholtz-Zentrum Dresden-Rossendorf
Graphene is considered a promising candidate for the nanoelectronics of the future. In theory, it should allow clock rates up to a thousand times faster than today’s silicon-based electronics. Scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) and the University of Duisburg-Essen (UDE), in cooperation with the Max Planck Institute for Polymer Research (MPI-P), have now shown for the first time that graphene can actually convert electronic signals with frequencies in the gigahertz range – which correspond to today’s clock rates – extremely efficiently into signals with several times higher frequency. The researchers present their results in the scientific journal “Nature”.

Organic light-emitting diodes (OLED) are mainly known from televisions and smartphone displays. They can be used as lighting objects in car tail lights or lights. The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP as a partner for customer-specific OLED development and production is now presenting OLED elements that can be integrated into textiles at the Electronics System Integration Technology Conference ESTC 2018 from September 18 - 21, 2018 in Dresden at booth no. 29.
The versatile OLEDs can not only light in color, they can also be designed in any shape and even transparent or dimmable. Applied on wafer-thin foils, they are...
Scientists at the Max Planck Institute for Intelligent Systems in Stuttgart invented a new and cost-effective method for making X-ray lenses with nanometer-sized features and excellent focusing capabilities. By using an advanced 3D printing technique, a single lens can be manufactured under a minute from polymeric materials with extremely favorable X-ray optical properties, hence the costs of prototyping and manufacturing are strongly reduced. High-throughput and high-yield manufacturing processes of such lenses are sought after world-wide, which is why the scientists have filed a patent for their invention.
X-ray microscopes are fascinating imaging tools. They uniquely combine nanometer-size resolution with a large penetration depth: X-ray microscopy or XRM is the...
