1. A method of transmitting point cloud data by an apparatus, the method comprising:
encoding the point cloud data;
encapsulating the encoded point cloud data into a file,
wherein the file includes multiple tracks,
wherein a track of the multiple tracks includes a sample entry including a parameter set for the point cloud data, the parameter set including identification information that provides an identifier for the parameter set, frame width information that indicates a frame width, and frame height information that indicates a frame height,
wherein a track of the multiple tracks includes a sample entry including information for a bounding box of the point cloud data, and
wherein the information for the bounding box includes position information of the bounding box and information for a scale of the bounding box; and
transmitting the file.
