¿µ¹®³»¿ë¿ä¾à This standard describes the technical and standard specifications (syntax and semantics) about the compressed domain merging of multiple tiles/slices into a single bitstream and selective streaming in VR video tile-based transmission and rendering through a head-mounted display (HMD) devices capable of tracking user¡¯s movements and a server which supports distributed processing. This standard can be applied to the tile-based VR video streaming system. This standard does not directly affect to or influenced by the referenced MPEG-Immersive standard but specifies the signaling details independently.
