Virtual worlds are still a major trend, whether in panorama videos, computer games or in planning processes in the industry. The delivery and storage standard MPEG-OMAF ensures that all VR devices speak the same language and are compatible with each other. The fully standardized HEVC tile-based streaming technology of Fraunhofer HHI will moreover enable a significant increase in the resolution of 360-degree videos with MPEG-OMAF. This is how high-definition video footage enters Virtual Reality. This technology will be shown at IFA 2018 in Berlin from August 31 to September 5 at the joint booth of Deutsche TV-Plattform (hall 26A, booth 203).
Streaming high-quality VR360 panoramic video with resolutions up to 8K consumes large amounts of bandwidth. Moreover, the encoded video requires decoding capabilities beyond 4K video at the receiving end, e.g. on VR glasses with a mobile phone.
Fully standardized tile-based streaming solves these issues by spatially segmenting the panoramic 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 into a single HEVC compliant video stream and decoded with a legacy hardware video decoder on the end device.
At IFA 2018, Fraunhofer HHI showcases a demonstrator for consistent VR 360 degree live video streaming with a resolution higher 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.

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...
