1. A method of encoding point cloud data by an apparatus, the method comprising:
encoding point cloud data;
encapsulating the point cloud data based on a file; and
transmitting the file,
wherein the file includes a track for atlas data for the point cloud data and a component track including the point cloud data,
wherein the track includes atlas parameter sample group information having a grouping type having an identifier for the sample group,
wherein the atlas parameter sample group information includes information for representing a number of setup units in the atlas parameter sample group information, and the setup units include at least one of an atlas sequence parameter set (ASPS), an atlas adaptation parameter set (AAPS), an atlas frame parameter set (AFPS), an essential supplemental enhancement information (ESEI), a non-essential supplemental enhancement information (NSEI), and
wherein the atlas parameter sample group information is identified based on the grouping type,
wherein the grouping type represents that samples in the track are related to atlas parameter sets in a sample group.
