Fraunhofer HHI shows latest video technologies at IBC

11.09.2018

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.

Im Focus: A step towards controlling spin-dependent petahertz electronics by material defects

The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.

Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...

Im Focus: Freiburg researcher investigate the origins of surface texture

Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.

Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Im Focus: Making the internet more energy efficient through systemic optimization

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.

Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.

Im Focus: New synthesis methods enhance 3D chemical space for drug discovery

After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.

"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
