scope:

Immersive live experience (ILE) systems consist of several devices such as cameras, displays and transmission networks from the source site to viewing sites, as described in [ITU-T H.430.1]. Synchronous signalling transmission including video and audio were studied in ISO/IEC JTC1/SC29/WG11 (MPEG), and MPEG media transport (MMT) [ISO/IEC 23008-1] is a well-suited approach for transporting synchronously several media from event sites to remote sites on ILE systems. However, MMT might not consider transporting spatial information, such as the X-Y-Z coordinate of objects, and stage effect information such as lighting. In order to utilize MMT for ILE systems, it needs to clarify the ILE profile of the MMT, which includes some constraints of the MMT specification, for example, usage of optional attributes.

This Recommendation identifies service configuration, system structure, media transport protocol and signalling information for immersive live experience (ILE) systems using MPEG media transport [ISO/IEC 23008-1] and specifies constraints to ISO/IEC 23008-1 for use in ILE systems.

The scope of this Recommendation includes:

- service configuration and system structure for MMT-based ILE systems

- media transport protocol for MMT-based ILE systems

- signalling information for MMT-based ILE systems.
