Media Presentation Description Grouping Descriptor for Omnidirectional Streaming

The patent segments the media content into multiple representation sets, where each representation set contains encoded media content at different resolutions and bitrates. This segmentation allows the system to manage complexity by organizing content into discrete, selectable units rather than handling all variations simultaneously, thereby maintaining high user experience quality while reducing system complexity.

The patent implements dynamic adaptation by allowing the streaming system to select and switch between different representation sets based on real-time network conditions and user device capabilities. This dynamic approach enables the system to optimize quality for each user's specific situation without requiring all possible high-quality representations to be actively managed simultaneously, thus improving user experience while controlling system complexity.

The patent segments media content into multiple representation sets with different resolutions and bitrates, organized within a media presentation description structure. This segmentation provides network adaptability by allowing selective delivery of appropriate content variants, while the structured organization reduces management complexity compared to handling unstructured multiple versions.

The patent creates a universal media presentation description framework that can accommodate multiple representation sets for different devices, networks, and playback scenarios. This multi-functional structure provides a single standardized interface for managing diverse content variants, thereby achieving network adaptability while reducing the complexity of managing different content formats through a unified system.

The patent segments media entities into grouped collections based on shared characteristics such as resolution, bitrate, or content type. This segmentation improves content organization efficiency by enabling batch processing and selective retrieval of related entities. The grouping metadata, while adding some volume, is structured to provide efficient indexing and querying capabilities that reduce overall processing requirements.

The patent performs preliminary grouping and organization of media entities during the content preparation and encoding phase, creating structured relationships and descriptors in advance. This preliminary action reduces processing overhead during playback by pre-establishing efficient access paths and reducing the need for complex real-time queries, thereby improving organization efficiency while managing metadata volume through advance preparation.
