Abstract: Disclosed herein is a method of transmitting point cloud data. The method may include acquiring point cloud data, encoding geometry information including positions of points of the point cloud data, generating one or more LODs based on the geometry information and selecting one or more neighbor points of each point to be attribute-encoded based on the one or more LODs, wherein the selected one or more neighbor points of each point are located within a maximum neighbor point distance, encoding attribute information of each point based on the selected one or more neighbor points of each point, and transmitting the encoded geometry information, the encoded attribute information, and signaling information.

Abstract: An apparatus for receiving a broadcast signal, the apparatus including a tuner configured to receive transport packets for signaling data and transport packets for delivery objects, a delivery object is a part of a file for video content of a broadcast service: a signaling parser configured to parse the signaling data including session information including an extended file delivery table providing information about delivery of the file, in which the extended file delivery table including file template information: and a data processor configured to generate location information for the file by substituting an identifier in the file template information with a Transport Object Identifier (TOI) in a header of a transport packet for the delivery object. Further, a payload of the transport packet for the delivery object carries a contiguous portion of the delivery object starting from a beginning of a first byte value through a byte value related to a sum of the first byte value and second byte value, the first byte value is a value of start offset information, that is followed by the payload, in the transport packet, and the second byte value is a length of the payload computed by subtracting a size of the header and a size of the start offset information from a total length of the transport packet.
