Tile Based DASH Streaming for Virtual Reality with HEVC from Fraunhofer HHI

03.01.2017

Fraunhofer HHI‘s technique for Compressed Domain Tile Aggregation with HEVC allows VR video applications with drastically reduced video bitrates and decoder requirements. Tile Based DASH Streaming with Fraunhofer HHI’s technique allows maintaining high video quality in the current viewport while streaming lower resolution outside the viewport. The approach can adapt the video bitstream to the current user viewport on-the-fly without heavy transcoding or storage of a large number of pre-rendered viewports on the server. At the CES fair 2017 in Las Vegas, Fraunhofer HHI will show this technology at Booth 20944, South Hall 1.

Tile Based DASH Streaming for Virtual Reality with HEVC – Enabler for high quality 360 degree video from Fraunhofer HHI at CES

Fraunhofer HHI‘s technique for Compressed Domain Tile Aggregation with HEVC allows VR video applications with drastically reduced video bitrates and decoder requirements. Tile Based DASH Streaming with Fraunhofer HHI’s technique allows maintaining high video quality in the current viewport while streaming lower resolution outside the viewport.

The approach can adapt the video bitstream to the current user viewport on-the-fly without heavy transcoding or storage of a large number of pre-rendered viewports on the server. Using Tile Based DASH Streaming, individual tiles are offered to the client which selects a configuration suitable to his viewport, throughput budget and decoder capabilities. At the CES fair 2017 in Las Vegas, Fraunhofer HHI will show this technology at Booth 20944, South Hall 1.

Ultra-high-resolution within the user viewport is required to achieve full immersion in VR video applications. Covering the full 360 degree video would easily lead to multiple times UHD resolution. Such large amount of data poses a major challenge to the whole chain of state-of-the-art video streaming.

The throughput required for streaming of 360 degree video over the public Internet cannot be provided for many users. Furthermore, most VR relevant devices such as mobile phones contain hardware video decoders that are tailored to conventional FullHD and 4K resolution services. Due to these limitations, a new approach for adaptivity of bitrate and resolution in VR video applications is required.

Fraunhofer HHI’s technique for Compressed Domain Tile Aggregation with HEVC overcomes the challenges of ultra-high resolution content on limited decoder capabilities. In a traditional service design, per-user or per-viewport orientation streams would be offered which does not scale well and comes at significant storage and encoding cost.

Using the technique of Fraunhofer HHI, a tailored bitstream for each user can be easily generated on-the-fly without intensive pro-cessing on the server or client side. Video content outside the users’ current viewport is transmitted in low quality or resolution, which allows a more efficient throughput and decoder utilization. Furthermore, Fraunhofer HHI‘s Compressed Domain Tile Aggregation solution enables usage of a single video decoder on end devices.

Complete and market ready streaming solutions can be implemented based on well-established standard families such as MPEG ISO Base Media File Format and MPEG DASH which are fully compatible to Fraunhofer HHI‘s Com-pressed Domain Tile Aggregation technique.

Im Focus: 'Nanochains' could increase battery capacity, cut charging time

How long the battery of your phone or computer lasts depends on how many lithium ions can be stored in the battery's negative electrode material. If the battery runs out of these ions, it can't generate an electrical current to run a device and ultimately fails.

Materials with a higher lithium ion storage capacity are either too heavy or the wrong shape to replace graphite, the electrode material currently used in...

Im Focus: Happy hour for time-resolved crystallography

Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Hamburg and the European Molecular Biology Laboratory (EMBL) outstation in the city have developed a new method to watch biomolecules at work. This method dramatically simplifies starting enzymatic reactions by mixing a cocktail of small amounts of liquids with protein crystals. Determination of the protein structures at different times after mixing can be assembled into a time-lapse sequence that shows the molecular foundations of biology.

The functions of biomolecules are determined by their motions and structural changes. Yet it is a formidable challenge to understand these dynamic motions.

Im Focus: Modular OLED light strips

At the International Symposium on Automotive Lighting 2019 (ISAL) in Darmstadt from September 23 to 25, 2019, the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, a provider of research and development services in the field of organic electronics, will present OLED light strips of any length with additional functionalities for the first time at booth no. 37.

Almost everyone is familiar with light strips for interior design. LED strips are available by the metre in DIY stores around the corner and are just as often...
