1. An information processing apparatus comprising:
circuitry configured to
generate a bitstream track storing a bitstream of content having a plurality of subpictures in a frame,
generate subpicture specifying information that is information for specifying a subpicture to be extracted among the plurality of subpictures in the bitstream track, the subpicture specifying information including tile region identification information that is identification information of a tile region including the subpicture to be extracted, and
generate a file including the bitstream track and an extract base track, the extract base track including the subpicture specifying information,
wherein the circuitry is further configured to store mapping information in the bitstream track by extending subpicture identification sample group information included in the bitstream track, the mapping information indicating a correspondence between the subpictures and the tile region.
