Abstract (en)
[origin: WO2021053261A1] The embodiments relate to methods and apparatuses for coding volumetric video. A method for encoding comprises receiving (610) a video presentation frame, where the video presentation represents a three-dimensional data; generating (620) one or more patches (410) from the video presentation frame, wherein the patches represent different parts of the content of the video presentation frame; determining (420, 630) which patch(es) of the generated one or more patches are to be encrypted (440), wherein the determination is based on a content of the patch; encrypting (440, 640) the determined patches with an encryption method that corresponds to a pre-defined authorization level; and encoding (450, 650) into a bitstream of a corresponding patch, information on the used encryption method.
