¿µ¹®³»¿ë¿ä¾à This standard describes the technical and standard specifications (syntax and semantics) about the scalable video coding with immersive video and adaptive streaming in VR video tile based transmission and rendering through a head-mounted display (HMD) devices capable of processing base layer and enhancement layer. This standard can be applied to the scalable 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.
