1 Scope

This document provides context, motivation and use case descriptions for a set of Moving Picture Experts Group (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 renderers.

This document:

• describes the motivators leading to the development of new MPEG standards that facilitate the streaming of media to render-based applications;

• differentiates between visual media distributed for video-based applications and visual media distributed to render-based applications;

• provides an overview of a media workflow from content production to content distribution;

• provides general information on relevant components of render-based systems including game engines and renderers

• identifies key components and resources (compute, storage, or network) comprising a heterogeneous set of immersive displays and other render-based applications;

• and documents use cases for end-to-end interoperability, including audio, video, graphics and systems aspects for render-based systems and applications.
