Live-Streaming Scene Metadata for Flexible Content Presentation

The patent segments the live-streaming content into distinct components: video content and supplemental enhancement information. The video content is encoded separately from the scene content information, allowing independent processing and flexible recombination at the playback end. This segmentation enables the system to maintain simple video encoding while adding rich scene information without significantly increasing overall complexity.

The patent introduces supplemental enhancement information as an intermediary element that bridges between the simple video content and the desired rich presentation. This intermediary carries scene content information (operations, environment, configurations) that enhances the video without requiring fundamental changes to the video encoding pipeline, thus resolving the contradiction between simplicity and versatility.

The patent extracts scene content information from the complex video stream and places it into a dedicated supplemental enhancement information structure. This extraction allows the scene information to be transmitted separately from the main video content, enabling optimized compression and selective transmission based on what scene information is actually needed, thus reducing overall data volume while maintaining information completeness.

The patent changes the parameter representation of scene information by encoding it in a standardized supplemental enhancement information format rather than transmitting raw scene data. This parameter transformation compresses the information efficiently while preserving all necessary scene content details, resolving the contradiction between information completeness and data volume.
