Abstract: 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.

Abstract: 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.

Abstract: The present disclosure relates to an information processing device and a method capable of storing data for each tile in a buffer.
Tile data of 3D object content is stored in a common buffer region, desired tile data is acquired from the buffer region on the basis of tile storage information for identifying the tile data stored in the buffer region, and the acquired tile data is processed. Further, a scene description file that stores a first accessor for storing tile data of 3D object content in a common first buffer region and a second accessor for storing tile storage information for identifying the tile data stored in the first buffer region in a second buffer region is generated. The present disclosure can be applied to, for example, an information processing device, an information processing method, or the like.

Abstract: A scene descriptive file describing a scene of 3D object content is generated, in the scene descriptive file, timed metadata identification information indicating that metadata of an associated external file changes in a time direction being stored in an MPEG_media extension, and timed metadata access information associating a camera object with the metadata being stored in the camera object. Furthermore, timed metadata that changes in the time direction is acquired on the basis of the timed metadata identification information and the timed metadata access information stored in the scene descriptive file, and a display image of the 3D object content is generated on the basis of the acquired timed metadata. The present disclosure is applicable to, for example, an information processing device, an information processing method, or the like.

Abstract: Provided is an appropriate viewing experience according to the intention of a provider. A metadata generation unit (122) generates timed playback information indicating a display order along time passage for playback of each scene of 6DoF content including a three-dimensional model in a three-dimensional space, and modified timed metadata including recommended viewing information indicating a viewpoint position and a line-of-sight direction at each time point along time passage for playback, and generates association information indicating that the timed playback information and the modified timed metadata correspond to each time point along the time passage for playback.

Abstract: In the scene description, a property corresponding to the method of playing back 3D data is selected on the basis of an extension and used for playback. In addition, in the scene description, an alternatives array corresponding to the method of playing back the 3D data is selected, and a property that is an element of the array is used for playback. In addition, a scene description file storing an extension for identifying a property for each method of playing back 3D data is generated. In addition, a scene description file storing a plurality of alternatives arrays having properties corresponding to the mutually same method of playing back 3D data as elements is generated.

Abstract: The present disclosure relates to an information processing apparatus and method capable of suppressing an increase in a load of a reproduction process.
A scene description file that describes a scene of 3D object content is generated, the scene description file including information associated with Media Presentation Description (MPD) that stores metadata of the 3D object content distributed by using Moving Picture Experts Group Dynamic Adaptive Streaming over HTTP (MPEG DASH) and information regarding encoding of Representation included in Adaptation Set in the MPD. Furthermore, the scene description file is analyzed, the 3D object content to be decoded is selected on the basis of the information regarding the encoding of the Representation, and the encoded data of the selected 3D content is decoded. The present disclosure can be applied to, for example, an information processing apparatus, an information processing method, or the like.
