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 IFA 2018 Fraunhofer HHI presents the latest developments in Video Coding & Analytics at the joint booth with Deutsche TV-Plattform Booth 203, Hall 26A, from August 31 to September 5, in Berlin, Germany.
VR360 Video Streaming with MPEG-OMAF and HEVC Tiles
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 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.
