Immersive media applications offer experiences that immerse the user in a virtual or hybrid environment and offer more degrees of freedom than with traditional 2D video content. Platforms that offer immersive media allow users to interact with content and other users in shared virtual or mixed-reality spaces. To address the need for an interoperable cross-platform exchange format, interactive and time-evolving solution for such 3D environments, International Organization for Standardization/International Electrotechnical Commission (ISO/IEC) Joint Technical Committee (JTC) 1/SC29/WGO3 MPEG Systems has standardized a scene description framework in ISO/IEC 23O9O-14,1 that serves as an entry point format to compose rich 3D scenes, referencing and positioning 2D and 3D assets in the scene, blending with the real world, rich interactivity and providing real-time media delivery. Carriage formats have also been defined for the delivery of the scene description data and of the linked assets based on the well-known and ubiquitous ISO base media file format (ISOBMFF) standard, i.e., ISO/IEC 14496-12.2
