Document Type and Number:
WIPO Patent Application WO/2023/200298
Kind Code:
A1
Abstract:
A transmission device of point cloud data, a method performed in a transmission device, a reception device, and a method performed in a reception device are provided. A method performed in a reception device of point cloud data according to the present disclosure may comprise the steps of: obtaining a geometry-based point cloud compression (G-PCC) file including point cloud data; and reconstructing a point cloud on the basis of temporal scalability information, wherein the temporal scalability information comprises first information relating to a temporal level track of the G-PCC file, and the first information specifies a restriction on the temporal level track on the basis of a sample entry type.
