1. A method of transmitting point cloud data, the method comprising:
encoding, by an encoder, the point cloud data including geometry information and attribute information; and
transmitting, by a transmitter, a bitstream including the encoded point cloud data and signaling information,
wherein the signaling information includes a sequence parameter set including point cloud data sequence related information, a geometry parameter set including geometry-related information, and an attribute parameter set including attribute-related information,
wherein the bitstream includes data units, each of the data units having type information and a payload,
wherein the type information indicates a type of data included in the payload,
wherein the payload includes one of a geometry data unit, an attribute data unit, the sequence parameter set, the geometry parameter set, and the attribute parameter set,
wherein the geometry data unit includes a geometry data unit header and a portion of the geometry information,
wherein the geometry data unit header includes at least one of identification information for specifying the geometry parameter set related to the geometry data unit or slice information related to the geometry data unit,
wherein the attribute data unit includes an attribute data unit header and a portion of the attribute information, and
wherein the attribute data unit header includes at least one of identification information for specifying the attribute parameter set related to the attribute data unit or information for specifying a geometry slice related to the attribute data unit.
