Server-Based Multi-Camera View Distribution Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-camera video image distribution systems, allowing each audience member to freely select camera views leads to a rapid spread of viewers across numerous camera images, disrupting the shared experience and increasing the number of streaming requirements, which impairs the attraction of a common viewing experience.
Innovation Solution
A server-based system that controls camera video image distribution by selecting candidates and generating options for audience terminals, ensuring a common camera view is maintained across selections, thereby restricting the spread of viewers and maintaining a consistent number of streaming views.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If each audience member is allowed to freely select camera video images from multiple points of view, then the adaptability and viewer satisfaction are improved, but the number of camera video images that need to be simultaneously distributed increases rapidly, and the shared viewing experience deteriorates
Solution Approach 1:
The patent segments the audience into multiple groups based on their selection preferences, and distributes different camera video images to different groups. This allows the system to maintain a manageable number of simultaneous streams while still providing diverse viewing options to individual viewers.
Solution Approach 2:
Instead of allowing each viewer to freely select from all available camera views (which would require distributing all views to all viewers), the system inverts the approach by assigning specific camera views to specific viewer groups, and viewers within each group select from their assigned subset. This dramatically reduces the total number of streams required.
2Ease of operation
If each audience member sequentially selects camera video images from multiple options, then the viewer's ability to access preferred views is improved, but the spread of viewers across different camera images increases, impairing the shared experience
Solution Approach 1:
The patent applies local quality by providing different selection options and control capabilities to different viewer groups. Each group receives a customized set of camera view options tailored to their preferences, while maintaining a common viewing experience within each group. This localized approach balances individual control with group cohesion.
3Stability of the object's composition
If the number of selectable camera video image points of view is limited, then the shared viewing experience is maintained, but the viewer's ability to select preferred views is restricted
Solution Approach 1:
The patent implements a dynamic system where the set of available camera video image options is not fixed but changes based on the selected viewpoint and progresses through a predetermined sequence. This dynamic adjustment allows the system to maintain a limited number of simultaneous streams while still providing viewers with access to a broader range of views over time, balancing shared experience with individual preference.

AI summary
An aspect of the present invention provides a server for controlling a camera video image to be distributed to an audience terminal for multi-camera video image distribution service for cyclic distribution of camera video images in a plurality of points of view to audience. The server includes a selector and a decider. The selector selects a plurality of candidates in each of selection opportunities that allow each audience member to select the camera video image to be distributed to the audience terminal. The decider decides the camera video image to be distributed to the audience terminal based on information indicating one of a plurality of options selected by each audience member. At least one of the plurality of candidates selected in at least one of the selection opportunities includes a common camera video image regardless of camera video images viewed by the audience when the plurality of candidates are selected.
