Abstract: System and methods for improved playback of a video stream are presented. Video snippets are identified that include a number of consecutive frames for playback. Snippets may be evenly temporally spaced in the video stream or may be content adaptive. Then the first frame of a snippet may be selected as the first frame of a scene or other appropriate stopping point. Scene detection, object detection, motion detection, video metadata, or other information generated during encoding or decoding of the video stream may aid in appropriate snippet selection.

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.
