More Information
Summary:Systems and methods are described for providing viewers of adaptive bit rate (ABR) streaming video with the option to view alternative streams in which an alternative tone mapping is applied to one or more regions of interest. The availability of streams with alternative tone mappings may be identified in a media presentation description (MPD) in an MPEG-DASH system. In some embodiments, the streaming video is divided into slices, and alternative tone mappings are applied to regions of interest within the slices. When a server receives a request from a client device for alternative tone mappings of different regions, slices with the appropriate mapping may be assembled on demand and delivered to the requestor as a single video stream. Tone mappings may be used, for example, to highlight particular players in a sporting event.
