Abstract
A point cloud data transmission method according to embodiments comprises the steps of: encoding geometry data including positions of points of point cloud data; encoding, on the basis of the geometry data, attribute data including attribute values of the points of the point cloud data; and transmitting the encoded geometry data, the encoded attribute data, and signaling information, wherein, in the step of encoding the geometry data, the geometry data can be compressed on the basis of the correlation between frames and the distribution of the points.
