Viewport-Based Media Retrieval in 3D Scene Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current presentation engines lack adequate support for handling multiple viewpoints and camera objects in 3D scenes, particularly in rendering media content that requires dynamic camera properties and viewer poses.
Innovation Solution
A system and method for controlling multiple camera objects, each associated with a specific view of media content, allowing for dynamic ranking, registration, and updating of camera objects to manage viewer-specific views and media content retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple camera objects are supported with dynamic properties, then the rendering capability for multi-view scenarios is improved, but the system complexity increases
Solution Approach 1:
The system segments the camera management by introducing separate camera objects, each encapsulating specific view parameters and properties. This allows independent control of multiple viewpoints without managing a monolithic complex system, resolving the contradiction by dividing the rendering task into manageable camera-specific segments.
Solution Approach 2:
The patent implements dynamic camera properties that can be adjusted in real-time, allowing the rendering system to adapt to different viewing scenarios. This dynamic capability enables versatile multi-view rendering while maintaining manageable complexity through parameterized control rather than hard-coded configurations.
2Measurement precision
If viewport-based and region-of-interest-based retrieval is implemented, then the media content delivery accuracy is improved, but the processing time increases
Solution Approach 1:
The system performs preliminary organization of media content based on viewport and region-of-interest parameters before actual rendering. By pre-processing and structuring media data according to potential viewing requirements, the system achieves accurate content delivery without incurring processing delays during real-time rendering.
Solution Approach 2:
The patent utilizes parameter-based control where media retrieval is optimized by changing retrieval parameters based on viewport and region-of-interest specifications. This allows the system to adjust retrieval precision dynamically, achieving accurate content delivery while minimizing processing time through parameter optimization rather than fixed high-precision retrieval.

AI summary
A device may receive information associated with a plurality of cameras where each of the cameras has an associated camera object. The device may associate a first camera object with a first viewer. The first camera object may have associated first extrinsic properties and associated first intrinsic properties. The device may associate a second camera object with a second viewer. The second camera object may have associated second extrinsic properties and associated second intrinsic properties. The device may send a registration request to a Media Access Function (MAF) where the registration request identifies the first camera object and the second camera object. The first viewer and the second viewer may update their preferred views of media content, in response, the device may send an update request to the MAF, where the request comprises updated information associated with the first camera object and updated information associated with the second camera object.
