摘要： A decrease in bit efficiency is suppressed. An information processing device includes an encoding unit (101) that encodes a picture including two or more subpictures to generate encoded data; a metadata generation unit (102) that generates subpicture mapping information including first size information of a first subpicture among the two or more subpictures and information that second size information of each of one or more second subpictures other than the first subpicture being considered the same as the first size information of the first subpicture; and a bitstream generation unit (103) that generates a bitstream including the encoded data and the subpicture mapping information.

摘要： The present disclosure relates to information processing apparatus and method that allow robustness of content reproduction to be improved.
Metadata regarding content is generated, the content expressing a three-dimensional object in a three-dimensional space and enabling a line-of-sight direction and a view-point position to be freely set at a time of reproduction, and the metadata including information enabling a bit rate to be selected at a time of distribution of the content. Metadata that includes, for example, as the above-described information, access information for a control file controlling reproduction of the content, is generated. The present disclosure may be applied to, for example, an image processing apparatus, an image encoding apparatus, or an image decoding apparatus.-

摘要： The present disclosure relates to an information processing apparatus and a method capable of suppressing an increase in load of reproduction processing.
A file storing a bitstream track storing a bitstream of content having a subpicture in a frame and an extract base track storing subpicture specifying information which is information for specifying a subpicture to be extracted in the bitstream track is generated. Further, a subpicture is extracted from the bitstream track and a bitstream is generated on the basis of the extract base track of the file. The present disclosure can be applied to, for example, an information processing apparatus, an information processing method, or the like.-

摘要： To provide an information processing apparatus, an information processing method, a reproduction processing apparatus, and a reproduction processing method that provide a user with a viewing experience with a high degree of freedom. A data input unit acquires data of a three-dimensional space configured as a single spatial three-dimensional object including a plurality of three-dimensional objects. A preprocessing unit generates three-dimensional object-specifying information for identifying a specific three-dimensional object included in a three-dimensional space. A file generation unit generates a file including data of a three-dimensional space and three-dimensional object-specifying information generated by the preprocessing unit.

摘要： Provided are an information processing apparatus, a reproduction processing apparatus, an information processing method, and a reproduction processing method that enable a client device to efficiently select a content configuration. A preprocessing unit generates content configuration selection information, with respect to one or a plurality of contents, for determining whether or not each of the contents is reproducible, each of the contents having a content configuration including one or more three-dimensional objects and space arrangement information therefor to represent a virtual space. A file generation unit generates a file including data about the virtual space and the content configuration selection information.

摘要： The present disclosure relates to an information processing device and an information processing method by which reproduction of a point cloud having no time information can be handled.
Metadata that includes reproduction information necessary to reproduce encoded data obtained by encoding one frame of a point cloud by V-PCC or G-PCC and that includes reproduction feasibility information to be used to determine feasibility of reproducing the encoded data is generated. The encoded data and the metadata are stored in a file having a predetermined file structure using the ISOBMFF technology. The present technology is applicable to a data generation device that generates a file into which encoded data of a point cloud having no time information is stored, for example.-

摘要： The present technology relates to an image processing apparatus and a file generation apparatus that make it possible to appropriately reproduce a BV content. An image processing apparatus includes: a file acquisition unit that acquires a file having a management region where information for management of a 3D object content is stored and a data region where a track in which streams included in the 3D object content are stored is stored, group information for selection, from a plurality of the streams included in the 3D object content, of the stream appropriate for reproduction of the 3D object content being stored in the management region; and a file processor that selects a plurality of the streams to be used for reproduction of the 3D object content on the basis of the group information. The present technology is applicable to a client apparatus.

摘要： There is provided an information processing apparatus, a reproduction processing apparatus, and an information processing method that improve data transmission efficiency. A preprocessing unit (102) generates, as scene configuration information indicating a configuration of a scene of 6DoF content including a three-dimensional object in a three-dimensional space, dynamic scene configuration information that changes over time and static scene configuration information that does not change over time, the static scene configuration information being scene configuration information different from the dynamic scene configuration information.
