METHOD, DEVICE AND STREAM FOR 3D VIDEO FORMAT Russian patent published in 2023 - IPC H04N21/81 H04N13/161 H04N13/275 

FIELD: volumetric video content.

SUBSTANCE: invention is related in particular to encoding and/or formatting of data representing volumetric content. According to the proposed solution, the first data representing the texture of the 3D scene is encoded into at least the first track, the second data representing depth associated with points of the 3D scene is encoded into at least a second track, the instructions for retrieving at least a portion of said first data and second data from at least a portion of said first track and second track is encoded into at least a third track. The first data is located in a plurality of first segments into which a first frame is divided, with a portion of the 3D scene associated with each first segment of the plurality of first segments. The second data is located in a plurality of second segments into which the second frame is divided, wherein the total number of second segments of the second frame is greater than the total number of first segments of the first frame. The resulting rendered content may be presented on an end user's viewing device, such as an HMD, according to a viewpoint orientation consistent with the instructions.

EFFECT: efficient encoding/decoding of data representing volumetric content.
