MPEG-I Scene Description: a scene description framework for interactive and Immersive media experiences

"Immersive media applications offer experiences which immerse the user in a virtual or hybrid environment and offer more degrees of freedom than with traditional 2D video content. Platforms providing immersive media often enable the user to interact with the content and/or with other users in shared virtual or mixed reality spaces. To address the need for an interoperable cross-platform exchange format, and interactive and time evolving solution for such 3D environments, ISO/IEC JTC 1/SC29/WG03 MPEG Systems has standardized a Scene Description framework in ISO/IEC 23090-14, 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 ISOBMFF standard i.e., ISO/IEC 14496-12."
