VR Snapshot Distribution Server Reducing Data Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing VR live broadcasting systems face challenges in efficiently distributing 3D snapshot data of virtual reality spaces, as the large data volume of 3D environments leads to increased load on distribution servers, and current methods do not effectively manage data compression or angle changes in real-time viewing.
Innovation Solution
A VR live broadcasting distribution system that includes a distributor terminal, viewer terminal, and distribution server, which constructs and distributes exterior appearance data of the 3D space including the avatar, allowing for compact data representation and dynamic angle changes through coordinate and texture data manipulation, reducing server load by generating VR snapshot data that maintains the 3D space as 3D data rather than captured images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire 3D space data is distributed to preserve the 3D form, then the viewing flexibility and 3D space integrity are improved, but the data volume and server load increase significantly
Solution Approach 1:
The patent extracts only the essential exterior appearance data (coordinate data and texture data) needed to reconstruct the 3D space, rather than distributing the entire 3D space data. This extraction process removes unnecessary components while preserving the core elements required for 3D visualization, thereby reducing data volume while maintaining viewing flexibility.
Solution Approach 2:
The patent applies local quality by focusing on and distributing only the exterior appearance characteristics of objects in the 3D space, rather than all internal details. By selectively transmitting coordinate data and texture data that define external surfaces, the system achieves efficient data compression while preserving the visual quality needed for 3D viewing.
2Quantity of substance
If the 3D space data is compressed to reduce data volume, then the server load is reduced, but the quality and detail of the 3D space representation deteriorates
Solution Approach 1:
The patent creates a simplified copy of the 3D space by extracting coordinate data and texture data that replicate the exterior appearance. This copy contains only the essential information needed to visually represent the 3D space, achieving compression while maintaining sufficient quality for viewing purposes.
Solution Approach 2:
The patent changes the data representation parameters by converting complete 3D space data into a simplified format containing only coordinate data and texture data. This parameter transformation reduces data volume while preserving the critical visual characteristics needed for 3D space representation.
3Ease of operation
If real-time angle changes are enabled for dynamic viewing, then the user experience is improved, but the processing load and system complexity increase
Solution Approach 1:
The patent performs preliminary action by pre-processing and extracting the exterior appearance data (coordinate data and texture data) before distribution. This pre-extraction creates a simplified data structure that enables real-time angle changes and dynamic viewing without requiring complex processing during operation, thereby improving user experience while controlling system complexity.

AI summary
A VR snapshot broadcasting distribution system, a distribution server, a control method for the distribution server, a program for the distribution server, and a data structure of a VR snapshot data, whereby a 3D space is kept in a 3D form and data of the 3D space is made compact are disclosed. An example distribution server includes: a shooting instruction input unit, to which unit a VR snapshot shooting instruction is input by a distributor or a viewer; an exterior appearance data constructor configured to construct exterior appearance data of the entire 3-dimensional space including the avatar, based on a VR snapshot shooting instruction; a VR snapshot data distribution unit configured to distribute, as VR snapshot data, the exterior appearance data of the entire 3-dimensional space including the avatar, which is constructed by the exterior appearance data constructor; and a display unit configured to display the VR snapshot.
