6DoF Scene Configuration Data Separation for Transmission Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for random access reproduction of 6DoF content require clients to receive and store both static and dynamic scene information, leading to inefficiencies in data transmission and processing costs due to the need for repeated transmission of static information.
Innovation Solution
An information processing apparatus that separates scene configuration information into dynamic and static components, allowing for the generation of distinct scene descriptions that change and remain constant over time, enabling efficient data transmission by storing and transmitting only necessary information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If both static and dynamic scene information are acquired for each random access point, then random access reproduction can be realized, but data transmission efficiency decreases and processing cost increases due to repeated transmission of static information
Solution Approach 1:
The scene description information is segmented into two distinct types: static scene description information (which remains unchanged across different random access points) and dynamic scene description information (which changes for each random access point). This segmentation allows the client to acquire only the necessary dynamic information for each random access point while reusing the static information, thereby reducing redundant data transmission and improving transmission efficiency while maintaining random access reproduction capability.
2Reliability
If both static and dynamic scene information are acquired for each random access point, then complete scene information is available for reproduction, but the amount of data to be received and processed increases
Solution Approach 1:
The static scene description information is extracted and separated from the dynamic scene description information. The client acquires the static scene description information once and reuses it across multiple random access points, while only acquiring the necessary dynamic scene description information for each specific random access point. This extraction and selective acquisition approach maintains complete scene information for reproduction while significantly reducing the total data volume that needs to be received and processed.
3Reliability
If static scene description information is transmitted repeatedly for each random access point, then all necessary information is provided, but transmission efficiency decreases
Solution Approach 1:
The static scene description information is prepared and made available in advance as a separate entity that can be reused. When a client needs to perform random access reproduction, it acquires the static scene description information once (or uses previously acquired information) and then only needs to acquire the specific dynamic scene description information for the desired random access point. This preliminary preparation and reuse approach ensures all necessary information is available while minimizing data reception time by eliminating repeated transmission of static information.

AI summary
There is provided an information processing apparatus, a reproduction processing apparatus, and an information processing method that improve data transmission efficiency. A preprocessing unit (102) generates, as scene configuration information indicating a configuration of a scene of 6DoF content including a three-dimensional object in a three-dimensional space, dynamic scene configuration information that changes over time and static scene configuration information that does not change over time, the static scene configuration information being scene configuration information different from the dynamic scene configuration information.
