    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: A video transmitting device according to embodiments of the present invention can comprise a pre-processor for processing video data, an encoder for encoding the pre-processed video data and a transmitting unit for transmitting the encoded video data. Additionally, the video transmitting device further comprises a projector for generating a picture and a projection parameter related to the picture by projecting the video data, and the pre-processor can view-select video data for a specific view from among the video data. Furthermore, the pre-processor of the video transmitting device can pack the video data into specific video data by view-analyzing the video data.
