3D Object Scene Description for Multi-Component Video Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional MPEG-I Scene Description does not support the simultaneous use of multiple video components for a single 3D object.
Innovation Solution
An information processing device and method that sets a component index with different values for each video component in the material layer of a scene description, allowing multiple video components to be stored and used simultaneously in a 3D object by associating them with different accessors in the buffer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional MPEG-I Scene Description is used, then the scene description structure is simple, but multiple video components cannot be simultaneously used for one 3D object
Solution Approach 1:
The patent segments video components by introducing component indices to distinguish different video components (e.g., luma, chroma) associated with a single 3D object. Each video component is assigned a unique index value, allowing the scene description to reference specific components individually while maintaining the overall structure.
Solution Approach 2:
The patent makes the material layer universal by enabling it to reference multiple video components through the component index mechanism. The same material layer structure can now handle single or multiple video components, making the scene description format adaptable to various rendering needs without requiring separate structures for each case.
2Manufacturing precision
If multiple video components are stored in separate buffers, then image quality improves, but data management complexity increases
Solution Approach 1:
The component index acts as an intermediary between the material layer and multiple video component buffers. Instead of directly managing multiple buffers, the system uses the index as a mediator to reference the appropriate buffer, simplifying the management interface while still enabling access to multiple high-quality video components.
Solution Approach 2:
The patent adds an indexing dimension to the video component reference system. Rather than managing multiple video components through separate named references, the system introduces an index dimension that allows sequential or selective access to components, reducing the complexity of buffer management while maintaining image quality.

AI summary
The present disclosure relates to an information processing device and method that enables simultaneous use of a plurality of video components for one object using a scene description. In an extension for the 3D object video defined in a material layer of a scene description file, a component index having a different value for each of video components is set to a video component included in the 3D object video. In addition, the video component is stored in a corresponding buffer on the basis of the component index, the video component is acquired from the buffer on the basis of the component index, and a display image is generated using the acquired video component. The present disclosure can be applied to, for example, an information processing device, an information processing method, or the like.
