Abstract: Techniques are disclosed for coding and delivering multi-view video in which the video is represented as a manifest file identifying a plurality of segments of the video available for download. The multi-view video may be partitioned spatially into a plurality of tiles that, in aggregate, encompass the entire spatial area of the video. The tiles are coded as segments contains coded video representing content contained within its respective tile. Tiles may be given different sizes based on saliency of the content within their respective regions. In this manner, tiles with high levels of interest may have relatively large spatial areas, which can lead to efficient coding in the presence of content motion.

Abstract: Improved media processing techniques includes media data formats with a “convenience” sample having both a snapshot and a delta description of a scene at the same media time. In other examples, improved media processing techniques include creating a temporary media sample having a merged snapshot or a merged delta in a context of a pre-render thread to improve performance of rendering performed in a context of a separate rendering thread.
