The Fraunhofer Heinrich Hertz Institute HHI is a world leader in the development for mobile and optical communication networks and systems as well as processing and coding of video signals. Together with international partners from research and industry, Fraunhofer HHI works in the whole spectrum of digital infrastructure – from fundamental research to the development of prototypes and solutions.
At IBC 2018 Fraunhofer HHI presents the latest developments in Vision & Imaging Technologies and Video Coding & Analytics at Fraunhofer booth 8.B80, from September 14-18, in Amsterdam, Netherlands.
Live End to End Streaming of VR360 10K Video with MPEG-OMAF and HEVC Tiles
Streaming high-quality VR360 panoramic video with resolutions up to 10K x 2K 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 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 IBC 2018, Fraunhofer HHI showcases the world's first standard-compliant end to end chain for live VR360 video streaming beyond 4K resolution. This includes high-resolution VR360 10K video capturing and live rendering from the Fraunhofer HHI Omnicam-360, 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 traffic. This demonstrates the need for even more efficient compression, which goes beyond the current state of the art 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 will showcase 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 at European mainland has been opened commercial productions in film park 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.
