Video Display Viewpoint Selection and Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In video distribution systems where multiple cameras capture the same scene from different viewpoints, it is challenging to appropriately display videos to users due to the vast number of videos stored on servers and the variability in camera types, leading to difficulties in selecting desired videos and ensuring continuous display, especially when the viewed viewpoint is not available.
Innovation Solution
A method that involves selecting a first viewpoint from multiple viewpoints, determining if it is available among subsequent videos, and if not, selecting a second viewpoint based on evaluation values such as view counts, to ensure continuous video display without interruption, while also presenting viewpoint information to the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cameras capture the same scene from different viewpoints, then the variety of video content increases, but the difficulty of selecting and displaying appropriate videos increases
Solution Approach 1:
The system changes the parameter of viewpoint selection by evaluating multiple viewpoints based on criteria such as view counts and selecting the most appropriate one dynamically. This resolves the contradiction by providing variety through multiple viewpoints while simplifying selection through automated evaluation and ranking of viewpoints based on predefined parameters.
2Quantity of substance
If the system stores vast number of videos on servers, then the availability of video content increases, but the time required to select desired videos increases
Solution Approach 1:
The system performs preliminary evaluation and ranking of viewpoints based on view counts before the user needs to select a video. By pre-processing and organizing the vast number of videos according to viewpoint popularity and relevance, the system enables rapid selection without requiring users to manually search through all stored videos, thus resolving the time consumption issue.
3Reliability
If the system automatically selects viewpoints based on evaluation criteria, then continuous video display is ensured, but the complexity of the selection algorithm increases
Solution Approach 1:
The system uses feedback from view counts and user interactions to automatically evaluate and select viewpoints. By incorporating feedback mechanisms that track which viewpoints are most popular and useful, the system ensures continuous video display while managing algorithmic complexity through data-driven decision making rather than complex rule-based systems.
4Ease of operation
If the system presents popular views to users, then user satisfaction increases, but the ability to show diverse viewpoints decreases
Solution Approach 1:
The system dynamically adjusts viewpoint selection by incorporating both popularity metrics and diversity considerations. Rather than statically presenting only popular views, the system adapts its selection criteria to balance user satisfaction from popular content with the need to expose users to diverse viewpoints, resolving the contradiction through flexible, context-aware viewpoint recommendation.

AI summary
A video display method includes: selecting, as a first selected viewpoint, one first viewpoint from among a plurality of first viewpoints corresponding to a plurality of second videos, and displaying a second video corresponding to the first selected viewpoint; determining whether the first selected viewpoint is included in a plurality of second viewpoints corresponding to a plurality of fourth videos captured after the plurality of second videos; and selecting one second viewpoint from among the plurality of second viewpoints as a second selected viewpoint and displaying a fourth video that is included in the plurality of fourth videos and corresponds to the second selected viewpoint, when the first selected viewpoint is determined to not be included in the plurality of second viewpoints.
