Video Playback Device Width Adjustment for Multi-Video Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video playback systems lack the ability to efficiently adjust and compare the display sizes of multiple videos simultaneously, making it difficult to accurately compare movements or actions in sports or performances captured by different cameras.
Innovation Solution
A video playback system that allows for the adjustment of display sizes of multiple videos based on user-designated widths, enabling equivalent display sizes and positions for enhanced comparison, using a network-connected video management device and playback device with features like vertical and horizontal width designation bars and display size adjustment buttons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple videos are displayed simultaneously for comparison, then the ability to compare movements and actions is improved, but the difficulty of accurately comparing due to different display sizes increases
Solution Approach 1:
The system changes the display size parameter of multiple videos dynamically based on user input. By receiving width designations from users and automatically adjusting video display sizes to match the designated width, the system ensures equivalent display dimensions for accurate comparison while simplifying the operation process
Solution Approach 2:
The system introduces an intermediary adjustment mechanism that mediates between the user's width designation input and the actual video display size. This intermediary process automatically calculates and applies the necessary scaling transformations, eliminating the need for users to manually adjust each video's display size while ensuring consistent comparison dimensions
2Ease of operation
If display sizes of multiple videos are manually adjusted, then the ease of operation is improved, but the time required for adjustment increases
Solution Approach 1:
The system performs preliminary automatic adjustment of video display sizes based on user-provided width designations before the comparison task begins. By pre-calculating and applying the necessary scaling transformations, the system eliminates time-consuming manual adjustment processes while maintaining ease of operation through simple width input
Solution Approach 2:
The system provides self-service functionality by automatically adjusting video display sizes without requiring manual intervention for each video. The system serves itself by taking user width designations and autonomously performing the scaling operations, thereby reducing both adjustment time and operational complexity

AI summary
A video playback device includes a processor that executes a procedure. The procedure includes, for plural respective videos, receiving designations of widths in a vertical direction or in a horizontal direction within display regions of the videos, and adjusting the relative display sizes between the plural videos such that the display sizes of the widths designated for the plural respective videos are equivalent.
