| ¿µ¹®³»¿ë¿ä¾à | This standard describes the standard signaling specifications (syntax and semantics) for signaling encryption information directly within the bitstream structures of V-PCC and G-PCC for copyright protection. For V-PCC, this standard defines DRM-related syntax within the atlas tile header to enable the application of independent encryption for each tile that constitutes an atlas. For G-PCC, it defines DRM-related syntax within the Geometry Parameter Set (GPS) and the Attribute Parameter Set (APS), respectively, to enable selective protection of geometry and attribute data that constitute the point cloud on a slice-by-slice basis. This standard can be applied to distribution and streaming systems for 3D point cloud content. | ||
