Claim 7:
8. A three-dimensional data decoding method comprising:
performing motion compensation on a plurality of decoded point clouds;
merging the plurality of decoded point clouds that have been motion compensated, to generate a reference point cloud;
decoding an N-ary tree structure of a current point cloud using the reference point cloud, where N is an integer greater than or equal to 2;
generating a decoded point cloud of the current point cloud from the N-ary tree structure of the current point cloud;
obtaining, from control information which is common to a plurality of point clouds, first information indicating whether execution of decoding using the reference point cloud is permitted; and
obtaining, from the control information, second information on a total number of the plurality of decoded point clouds, when the first information indicates that the execution of the decoding using the reference point cloud is permitted.
