Data generation apparatus, data generating method, data reproduction apparatus, and data reproducing method

The present technique relates to a data generation apparatus, a data generating method, a data reproduction apparatus, and a data reproducing method capable of enabling a user to enjoy an HDR image. HDR information designated by HDR designating information is acquired from a file storing a track of a stream including the HDR information which is configured with feature information representing features of luminance of an HDR (high dynamic range) image having a dynamic range higher than that of an STD (standard) image and conversion information representing a conversion rule of converting the one of the STD image and the HDR image into the other and a target track including the HDR designating information designating the HDR information which is to be applied to the target track of interest in the HDR information of the track. The present technique can be applied, for example, to the case of applying HDR information to a subtitle having an SMPTE-TT format using XML.

20170070552 · 2017-03-09 · ·

A reception apparatus includes circuitry configured to receive a digital broadcast signal. Based on a media presentation description (MPD), which conforms to the moving picture expert group-dynamic adaptive streaming over HTTP (MPEG-DASH) standard and is transmitted in the digital broadcast signal or via a communication network, the circuitry performs at least one of selection or grouping of components according to a level of a component hierarchy associated with the components, and controls playback of content of at least one of the components.

Sharing web application program guide content items over home networks

Digital living network alliance (DLNA) hypertext markup language 5 (HTML5) remote user interface (RUI) or VidiPath technologies are extended such that a W3C-defined <iframe> element facilitates incorporation of RUI-wrapped content into a client user interface that is a web application designed on the HTML5 RUI or VidiPath technology to ensure that remote user interface components of the RUI-wrapped content are rendered as an HTML5 RUI/VidiPath server expects, including any authentication protocol needed to verify client capability. In this way, search and playback of content, previously made available through monolithic web application (web app) based Electronic Program Guides (EPG) over a home network, are distributed without losing the programmable and graphics components provided when playing that same content via the monolithic web app EPG.

Adaptive streaming of geometry-based point clouds

Systems, methods, and instrumentalities are disclosed for receiving content related to geometry-based point clouds. A client device may receive a media presentation description (MPD) file from a content server, A set of pre-selection elements may be identified from the MPD file. One or more adaptation sets associated with at least one pre-selection element of the set of pre-selection elements may be identified. The adaptation set(s) may be indicated by an attribute associated with one of the pre-selection elements. A geometry-based point cloud compression (GPCC) tile identifier associated with a viewport may be determined. The GPCC tile identifier may be determined based on a first descriptor received in the MPD file. One or more adaptation sets associated with the GPCC tile identifier may be selected using a second descriptor. A point cloud component associated with the selected one or more adaptation sets may be requested. Point cloud component may be received.
