TEMPORAL SCALABILITY IN GEOMETRY POINT CLOUD COMPRESSION (G-PCC)

Abstract:

Example devices and techniques are disclosed for incorporating temporal identification information in geometry point cloud compression syntax structures. An example device for decoding point cloud data includes memory configured to store the point cloud data and one or more processors implemented in circuitry and communicatively coupled to the memory. The one or more processors are configured to determine a value of a temporal identifier (ID) of a syntax structure and decode the point cloud data based on the value of the temporal ID. The temporal ID of the syntax structure identifies a temporal layer to which point cloud data associated with the syntax structure belongs.
