1. A reproduction apparatus comprising:
a metadata acquisition section configured to acquire metadata that includes
reproduction information necessary to reproduce a bitstream from among 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 bitstream generated from the 3D data; and
a reproduction section configured to reproduce the bitstream based on a file in which the bitstream 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 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,
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, and
wherein the metadata acquisition section and the reproduction section are each implemented via at least one processor.
