Dynamic Scenes and Real-Time Updates in MPEG-I

Dynamic scenes in MPEG-I Scene Description are facilitated through the MPEG_scene_dynamic extension, leveraging JSON Patch operations (RFC 6902) to enable real-time updates to immersive media. This feature significantly enhances the user experience by allowing modifications to scenes without requiring full reloads.

The dynamic updates follow a structured pipeline, involving the Scene Update Manager, Dynamic Scene Pipeline, and Patch Processor, ensuring consistency and integrity in real-time scene management. JSON Patch operations such as add, remove, replace, move, copy, and test are supported, offering comprehensive control over immersive media content.

Figure 2 highlights the components involved in processing dynamic scene updates, emphasizing the robust architecture that ensures efficient and precise real-time modifications.
