Assignee: SONY GROUP CORPORATION
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  G | IPC H

Claim 9:
10. An information processing method executed by an information processing device, the method comprising:
generating metadata that includes
reproduction information necessary to reproduce a plurality of bitstreams generated from 3D data having no time information, and
reproduction feasibility information to be used to determine feasibility of reproducing the plurality of bitstreams generated from the 3D data; and

generating a file in which the plurality of bitstreams generated from the 3D data and the metadata are stored,
wherein the reproduction information includes
bitstream combination information that indicates a combination of bitstreams among the plurality of bitstreams to be used for reproduction, and
reproduction start point information that indicates a reproduction start point,

wherein the reproduction start point information indicates a bitstream among the plurality of bitstreams to be reproduced first,
wherein the reproduction information further includes a V-PCC Unit Header as information for reconstructing the 3D data from the plurality of bitstreams,
wherein the V-PCC Unit Header is signaled using a V-PCC still image format, wherein the reproduction feasibility information is indicated using a structure of a file configuration of an ItemProperty within the generated file,
wherein the reproduction feasibility information includes information that indicates that each bitstream of the plurality of bitstreams is a part of data forming the 3D data, and
wherein the reproduction feasibility information further includes, as determination information for allowing a determination that an item is not able to be singly displayed, information that indicates a hidden image.
