Abstract: Disclosed herein is a method of transmitting point cloud data. The method may include encoding geometry data of the point cloud data, encoding attribute data of the point cloud data based on the geometry data, and transmitting the encoded geometry data, the encoded attribute data and signaling data, the geometry encoding includes splitting the geometry data into one or more prediction units, and inter-prediction encoding the geometry data by selectively applying a motion vector to each of the split prediction units, and the signaling data includes information for identifying whether the motion vector is applied for each prediction unit.
