Abstract: This three-dimensional data encoding method comprises generating a plurality of frame data items by encoding point cloud data of a plurality of frames (S12021), and generating a bitstream containing the plurality of frame data items (S12022). Each of a plurality of processing unit data items includes a frame identifier indicating a frame to which the processing unit data belongs and a processing unit identifier indicating a processing unit corresponding to the processing unit data. The values of the plurality of frame identifiers corresponding to the plurality of frame data items arranged in the bitstream are set in a predetermined order. The values of the plurality of processing unit identifiers corresponding to the plurality of processing unit data items arranged in the frame data are set in an arbitrarily defined order.

Abstract: In a three-dimensional data encoding method, a bitstream is generated by encoding a plurality of sub-spaces in a target space that comprises a plurality of three-dimensional points, the bitstream comprising a plurality of encoded data corresponding to the plurality of sub-spaces. In generating the bitstream, a list of information about the plurality of sub-spaces, which are mapped to a plurality of identifiers allocated to the plurality of sub-spaces, is stored in first control information shared by the plurality of encoded data in the bitstream (S4531), and the identifiers, allocated to the sub-spaces that correspond to the encoded data, are stored in each of the headers of each of said plurality of encoded data (S4532).
