6DoF Content Selection Indexing for Reproducible Virtual Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing client devices struggle to efficiently select a content configuration for 6DoF content due to the lack of appropriate information for determining which content configurations can be reproduced, necessitating inefficient analysis of entire scene descriptions and AdaptationSets.
Innovation Solution
A preprocessing unit generates content configuration selection information, which is stored in a scene description file, providing indexes for decoding, rendering, and reproduction capabilities, allowing clients to efficiently select a content configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the entire scene description is analyzed to determine reproducible content configurations, then the client can make an informed selection, but the processing time and computational resources increase significantly
Solution Approach 1:
The server performs preliminary analysis of the scene description and extracts only the necessary reproduction capability information before transmitting it to the client. This pre-processing eliminates the need for the client to analyze the entire scene description, thereby reducing selection time while maintaining selection accuracy.
Solution Approach 2:
The patent extracts specific reproduction capability parameters from the complete scene description and transmits only these extracted parameters to the client. This selective transmission reduces data volume and processing requirements on the client side while preserving the essential information needed for accurate content configuration selection.
2Measurement precision
If detailed scene description information is transmitted to the client, then the client can accurately determine reproducible content, but the data transmission volume and network bandwidth consumption increase
Solution Approach 1:
The server extracts only the essential reproduction capability parameters from the complete scene description and transmits these extracted parameters to the client. This selective extraction and transmission significantly reduces data volume while maintaining the accuracy needed for determining reproducible content configurations.
3Adaptability or versatility
If the client processes multiple three-dimensional model data simultaneously, then the degree of freedom in reproduction processing increases, but the processing capability requirement increases
Solution Approach 1:
The server pre-analyzes the scene description to determine which content configurations are reproducible based on the client's capabilities. By performing this analysis beforehand and providing only the suitable configurations to the client, the system enables flexible reproduction processing without requiring the client to have high processing capabilities for analyzing all possible configurations.
Data Source
AI summary
Provided are an information processing apparatus, a reproduction processing apparatus, an information processing method, and a reproduction processing method that enable a client device to efficiently select a content configuration. A preprocessing unit generates content configuration selection information, with respect to one or a plurality of contents, for determining whether or not each of the contents is reproducible, each of the contents having a content configuration including one or more three-dimensional objects and space arrangement information therefor to represent a virtual space. A file generation unit generates a file including data about the virtual space and the content configuration selection information.
