Claim 6:
7. 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; and
generating a decoded point cloud of the current point cloud from the N-ary tree structure of the current point cloud;
wherein the decoding of the N-ary tree structure of the current point cloud includes:
entropy decoding the N-ary tree structure of the current point cloud; and
controlling a probability parameter to be used in the entropy decoding, based on the reference point cloud.
