Video Reproduction Device with Dynamic Pane Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In facility training systems, using multiple display devices to show videos of different facility operations increases costs, and existing methods that split a single screen into areas for multiple videos restrict user detail viewing.
Innovation Solution
A video reproduction device and method that synchronously reproduce different videos on a main and sub pane, allowing switching between videos on the main and sub panes based on user input or predefined settings, enabling detailed observation of each video.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple display devices are provided to display each video separately, then the user can observe each video in detail, but the cost of the training device increases
Solution Approach 1:
The patent combines multiple video displays into a single display device by dividing it into multiple panes (main pane and sub panes). Different videos are displayed simultaneously in different panes, allowing users to observe multiple videos in detail without requiring multiple separate display devices. This reduces system cost while maintaining detailed video observation capability.
Solution Approach 2:
The display screen is segmented into multiple functional areas (main pane and sub panes) where each pane can display different videos. This segmentation allows simultaneous detailed viewing of multiple videos within a single display device, resolving the contradiction between needing multiple devices and wanting to reduce cost.
2Device complexity
If a single display device screen is divided into multiple areas for multiple videos, then the cost is reduced, but the user cannot observe the image displayed in a small area in detail
Solution Approach 1:
The patent implements dynamic switching between displaying multiple videos simultaneously in panes and displaying a single video in full screen. When detailed observation is needed, the system can switch to full-screen mode for the selected video, providing both cost efficiency (single display device) and detailed observation capability (full-screen display).
Solution Approach 2:
The single display device serves multiple functions: it can display multiple videos simultaneously in divided panes for comparison viewing, and it can display a single video in full screen for detailed observation. This multi-functionality resolves the contradiction by adapting to different viewing needs within the same hardware configuration.
3Adaptability or versatility
If different videos are displayed on main pane and sub pane simultaneously, then the user can compare videos, but the sub pane video size is smaller and harder to observe in detail
Solution Approach 1:
The system allows dynamic switching between pane display mode (for video comparison) and full-screen display mode (for detailed observation). Users can first compare videos in the divided pane layout, then switch to full-screen mode for the video of interest to observe details, thus resolving the contradiction between comparison capability and detail observation.

AI summary
A reproduction unit synchronously reproduces different videos recorded in the same time zone on each of a main pane and a sub pane of which a size is smaller than a size of the main pane of a reproduction screen having the main pane and the sub pane. A reproduction switching unit switches the video reproduced on the main pane to the video reproduced on the sub pane during a reproduction of the video by the reproduction unit.
