Next-Generation Video Compression Enables 360 VR Streams Over 5G Networks

April 20, 2019 / uploadvr

Known worldwide for its contributions to the MPEG format — the compression technology used in MP3 audio files and MP4 videos — Germany’s Fraunhofer has recently turned its attention to the next frontier in media: virtual reality. After unveiling affordable VR headset microdisplay hardware last year, the company is now showing off next-generation video compression software using the new MPEG-OMAF standard, the first VR specification enabling 360-degree videos to stream over 5G networks.Based in “significant” part upon Fraunhofer video compression technologies, MPEG-OMAF breaks wraparound videos into grids of tiles encoded at multiple resolutions. The explanatory image above uses red tiles to indicate areas that are being streamed at low resolution, versus normally colored tiles that are being streamed at high resolution.Unlike traditional videos, which stream from servers at one user-selected resolution, these VR videos dynamically use high-resolution tiles...
