METHODS AND DEVICE FOR ADAPTIVE POINT CLOUD STREAMING Russian patent published in 2023 - IPC H04N19/70 

FIELD: data transmission.

SUBSTANCE: invention relates to means for adaptive streaming video-based point cloud compression (V-PCC) using an adaptive HTTP streaming protocol such as DASH MPEG. PCD PC related information is transmitted in a Media Presentation Description (MPD) for Dynamic Adaptive Streaming over HTTP (DASH), wherein the DASH MPD includes information indicating at least: (1) a basic adaptation set (AS) for the point cloud, the basic AS including information indicating at least: (i) a unique codec attribute value indicating that the basic AS corresponds to the V-PCC data, (ii) an initialization segment comprising at least one set of V-PCC sequence parameters for representing the PC, and (2) a plurality of AS set components, wherein each of the plurality of AS components corresponds to one of the plurality of V-PCC components and includes information indicative of at least: (a) a V-PCC Component descriptor specifying the type of the corresponding V-PCC component, and (b) at least one property of the corresponding V-PCC component. MPD DASH is transmitted over the network.

EFFECT: increased transmission efficiency of 3D point clouds.
