Abstract: Methods, data processing systems and machine readable non-transitory storage media are described that can provide, in one embodiment, a non-time based description of types of metadata in a time based metadata track that can be associated with, in time, a time based media track. The description can include a set of keys, or other identifiers, that specify the types of metadata in the metadata track, and the description can also include values describing the structure of each key and values describing how to interpret each key.

Abstract: Embodiments of the present disclosure provide techniques for rendering content from a media item. According to these embodiments, from a file of the media item, track(s) in a group data structure corresponding to the type of content are identified as candidate track(s). From other tracks in the file, a determination may be made whether another track corresponds to the type of content. When another track corresponds to the type of content, feature tags in the file that are associated may be compared with the other track to capabilities of a player device that is to render the type of content. When the feature tags match capabilities of the player device, the other track may be included as a candidate track. Thereafter, a track may be selected from the candidate tracks and rendered by the player device.

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.
