3D Scene Description Track Referencing to Curb Redundant Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional scene description methods result in redundant track designation, leading to an unnecessary increase in data amount.
Innovation Solution
An information processing device and method that generates a scene description file with track information to designate specific tracks as reference targets, reducing redundant data by accessing other tracks efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all tracks are designated in scene description, then complete track information is provided, but data amount of scene description unnecessarily increases
Solution Approach 1:
The patent extracts only the necessary track information from the complete track list. Instead of including all track designations in the scene description, it selectively includes only those tracks that are actually referenced by scene nodes, thereby removing redundant information while maintaining completeness of necessary data.
Solution Approach 2:
The patent applies partial action by including only the subset of tracks that are actually needed for the scene description, rather than including all tracks. This partial inclusion strategy reduces the data amount while ensuring that all necessary track information is present for proper scene reconstruction.
2Quantity of substance
If track reference information is optimized, then data amount is reduced, but track access efficiency may be affected
Solution Approach 1:
The patent performs preliminary analysis during scene description generation to identify which tracks are actually referenced by scene nodes. This preliminary identification allows the system to pre-select only the necessary tracks for inclusion in the scene description, optimizing both data size and access efficiency by avoiding unnecessary track references.
Solution Approach 2:
The patent introduces an intermediate processing step that analyzes the relationship between scene nodes and tracks. This intermediary analysis acts as a mediator that determines the optimal subset of tracks to include, balancing data reduction with efficient track access by establishing precise reference relationships.

AI summary
The present disclosure relates to an information processing device and method that enable an increase in data amount of scene description to be curbed. A scene description file including track information that designates, as a reference target, some tracks with information for accessing other tracks, from among a plurality of tracks of a file container that manages information regarding data of the 3D object content is generated. Also, data of the 3D object content managed in all the tracks is obtained on the basis of the scene description file including the track information that designates, as a reference target, some tracks with information for accessing other tracks from among the plurality of tracks of the file container and a reference relationship among the tracks. The present disclosure can be applied to, for example, an information processing device, an information processing method, or the like.
