Document Type and Number:
WIPO Patent Application WO/2023/090906
Kind Code:
A1
Abstract:
A transmission device for point cloud data, a method performed by the transmission device, a reception device, and a method performed by the reception device are provided. A method performed by a reception device for point cloud data, according to the present disclosure comprises the steps of: acquiring temporal scalability information about point cloud in three-dimensional space on the basis of a G-PCC file; and restoring three-dimensional point cloud on the basis of the temporal scalability information, wherein the temporal scalability information includes a first syntax element and a second syntax element for the three-dimensional point cloud, the first syntax element indicates the number of temporal levels within a track, the second syntax element indicates whether the three-dimensional point cloud is carried to a multi-temporal level track, and the second syntax element can be determined on the basis of the value of the first syntax element.
