1. A three-dimensional data encoding method comprising:
generating frame data items by encoding point cloud data items of frames; and
generating a bitstream including the frame data items, wherein
each of the frame data items includes processing unit data items corresponding to processing units obtained by dividing one frame,
each of the processing unit data items includes an encoded geometry information item and an encoded attribute information item, the encoded geometry information item being obtained by encoding a geometry information item of three-dimensional points included in a processing unit corresponding to the processing unit data item, the encoded attribute information item being obtained by encoding an attribute information item of the three-dimensional points included in the processing unit corresponding to the processing unit data item,
at least one of the frame data items includes a first parameter set for the processing unit data items, a second parameter set for the encoded geometry information items, and a third parameter set for the encoded attribute information items,
each of the processing unit data items includes a frame identifier indicating a frame to which the processing unit data item belongs and a processing unit identifier indicating a processing unit corresponding to the processing unit data item,
values of the frame identifiers corresponding to the frame data items placed in the bitstream are set in a predetermined order, and
values of the processing unit identifiers corresponding to the processing unit data items placed in the frame data item are set in an arbitrary order.
