Information technology - Coded representation of immersive media - Part 27: Media and architectures for render-based systems and applications

This document provides context, motivation, and use case descriptions for a set of MPEG standards that collectively deliver media directly to render-based applications such as game engines with a renderer component, or standalone renderers. Emerging examples where such applications are especially relevant include “metaverse” applications and immersive displays where such displays provide an interface to components (e.g., renderers) of existing game engines; e.g., Unreal Engine by Epic Games, Inc. and Unity by Unity Technologies. This document:(1) describes the motivators leading to the development of new MPEG standards that facilitate the streaming of media to render-based applications;(2) provides an overview of a media workflow from content production to content distribution;(3) provides general information on relevant components of render-based systems including game engines, and renderers;(4) differentiates between visual media distributed for video-based applications and visual media distributed to render-based applications;(5) identifies key components and resources (compute, storage, or network) comprising a heterogeneous set of immersive displays and other render-based applications; and(6) documents use cases for end-to-end interoperability, including Audio, Video, Graphics and Systems aspects for render-based systems and applications.
