    Abstract: A display device according to the present disclosure includes: a reception circuit that is configured to receive a piece of first image data, a piece of second image data, and a piece of third image data in this order, the piece of first image data having one or a plurality of pixel values included in an entire image having a first resolution, the piece of second image data having one or a plurality of pixel values included in a partial image having a second resolution higher than the first resolution, and the piece of third image data having one or a plurality of pixel values included in the entire image; a display section including a first plurality of pixels, a second plurality of pixels, and a third plurality of pixels; and a display drive circuit that is configured to perform first driving, second driving, and third driving, the first driving in which the first plurality of pixels is driven in units of a first number of pixels on the basis of the piece of first image data, the second driving in which the second plurality of pixels is driven in units of a second number of pixels on the basis of the piece of second image data, the second number being smaller than the first number, and the third driving in which the third plurality of pixels is driven in units of the first number of pixels on the basis of the piece of third image data.

    Abstract: 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.
