摘要： There is provided 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： 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 apparatus and an information processing method that are capable of distributing higher-quality G-PCC streams. When G-PCC streams obtained by encoding Point Cloud data according to G-PCC are generated, there are generated spatial positional information indicating spatial positions of respective pieces of partial Point Cloud data that represent individual parts into which the Point Cloud data is segmented, and grouping information that groups the partial Point Cloud data. The present technology is applicable to a generating apparatus that generates G-PCC streams, for example.

摘要： The present disclosure relates to an information processing apparatus and method capable of suppressing an increase in load of reproduction processing.
The metadata including the spatial configuration information of the subgroup and the dependency information of the subgroup and the layer-group is generated on the basis of the bitstream of the geometry of the 3D data, and the file storing the bitstream and the metadata are generated. Further, on the basis of the spatial configuration information of the subgroup and the dependency information of the subgroup and the layer-group stored in the file as metadata, a bitstream of the geometry of the 3D data corresponding to the desired layer-group and the subgroup stored in the file is extracted, and the extracted bitstream is decoded. The present disclosure can be applied to, for example, an information processing apparatus, an information processing method, or the like.-

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.

摘要： Provided are an information processing device, an information processing method, a reproduction processing device, and a reproduction processing method that reduce the amount of information and provide a viewer with a high-quality viewing experience. A preprocessing unit individually generates SubSample information used for decoding each of SubSamples, which are a plurality of component streams, in a content stream including the SubSamples. The file generation unit generates a file including the SubSamplel information generated by the preprocessing unit.

摘要： The present disclosure provides an information processing apparatus, information processing method, reproduction processing apparatus, and reproduction processing method, capable of providing a viewing experience that meets the viewer's requests. An encoding unit (121) encodes point cloud data in such a way as to have a phased hierarchical structure corresponding to a level of detail (LoD) indicating a level of quality to generate a bitstream being constituted of a data region including one or more geometry slices. A metadata generation unit (125) generates partial slice-specific information being used for specifying a correspondence of the LoD to a partial slice used as a partial region corresponding to the LoD in the geometry slice. A file creation unit (126) creates a file including the partial slice-specific information.

摘要： The present disclosure relates to an information processing device and method that enable an increase in data amount of scene description to be curbed. A scene description file including track information that designates, as a reference target, some tracks with information for accessing other tracks, from among a plurality of tracks of a file container that manages information regarding data of the 3D object content is generated. Also, data of the 3D object content managed in all the tracks is obtained on the basis of the scene description file including the track information that designates, as a reference target, some tracks with information for accessing other tracks from among the plurality of tracks of the file container and a reference relationship among the tracks. The present disclosure can be applied to, for example, an information processing device, an information processing method, or the like.

摘要： The present disclosure relates to an information processing device and method capable of suppressing an increase in processing load when randomly accessing scene descriptions.
As update information for updating spatial arrangement information for arranging at least one 3D object in a 3D space, initial value reference difference information that is difference information which uses an initial value of the spatial arrangement information as a reference, or post-update information in which an update to the initial value reference difference information is reflected in the initial value of the spatial arrangement information, is generated. Then, an update file which stores the update information is generated, and the initial value reference difference information or the post-update information is stored in the update file as a random access point. The present disclosure can be applied in, for example, an information processing device, an information processing method, or the like.-

摘要： The present disclosure relates to an information processing device and method capable of inhibiting an increase in a load on reproduction processing.
Scalable decoding information is generated on the basis of a depth of a slice in the G-PCC content and a dependency relation between slices and is stored in the metadata area of the content file that stores the G-PCC content. Further, on the basis of the scalable decoding information stored in the metadata area of the content file, any slice of the G-PCC content is extracted from the content file and is decoded. The present disclosure can be applied to, for example, an information processing device, an information processing method, or the like.
