1. A point-cloud decoding device comprising:
a geometry information decoder that decodes a flag that controls whether to apply a method in which octree, quadtree, and binary tree division is adaptively carried out or not; and
an attribute-information decoder that decodes a flag that controls whether to apply “scalable lifting” or not; wherein,
a restriction is set not to apply the “scalable lifting” when the method is applied.
