There is provided an information processing device that distributes live data to a first user (terminal device), the information processing device performing control related to interaction data from the first user on the basis of information of a delay between the first user that transmits the interaction data with respect to the live data and the information processing device, or a delay between a second user (terminal device) that receives the interaction data from the first user with respect to the live data and the first user.

Information processing device, information processing method, and information processing system

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.

Information processing device and information processing method

A decrease in bit efficiency is suppressed. An information processing device includes an encoding unit () that encodes a picture including two or more subpictures to generate encoded data; a metadata generation unit () 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 () that generates a bitstream including the encoded data and the subpicture mapping information.

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.

Information processing apparatus and method

There is provided an information processing apparatus, a reproduction processing apparatus, and an information processing method that improve data transmission efficiency. A preprocessing unit () 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.

Information processing apparatus, reproduction processing apparatus, and information processing method

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.

Information processing apparatus, information processing method, and program

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.

Image processing apparatus and file generation apparatus

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.

Information processing apparatus and information processing method

There are provided an information processing apparatus, an information processing method, and a program. The information processing apparatus includes a generating unit configured to generate a content file including object selection information for selecting object audio data in accordance with a display state of an image, in which the generating unit stores the object selection information in a metadata file included in the content file.

The present disclosure relates to a reproducing device, a reproducing method, a recording device, a recording method, a reproducing/recording device, a reproducing/recording method, and a program capable of supporting more appropriate 3D model display. A reproduction processing unit reproduces free visual point moving image content including a free visual point moving image stream and an edit data stream, and display of a 3D model arranged in a space recreated by the free visual point moving image stream in accordance with basic information set in edit data constituting the edit data stream is controlled with reference to additional information set in the edit data.
