Video Playback Device Dynamic Position Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video playback systems lack the ability to efficiently align and compare multiple videos side-by-side for instructional purposes, such as sports or performance analysis, as they typically fix video positions and sizes in advance, limiting flexibility and precision in display adjustments.
Innovation Solution
A video playback device and method that allows for dynamic adjustment of video positions and sizes based on user input, using horizontal or vertical bars to align designated positions, enabling flexible placement and comparison of multiple videos within a playback region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video positions and sizes are fixed in advance, then system complexity is reduced, but adaptability and ease of operation deteriorate
Solution Approach 1:
The system automatically calculates and adjusts video placement positions based on user-designated positions within each video. The processor autonomously determines the optimal placement to align designated positions across multiple videos, eliminating the need for manual positioning adjustments while maintaining operational simplicity.
Solution Approach 2:
The system dynamically changes the placement position parameters of videos based on designated positions. By allowing users to specify positions within videos and automatically adjusting the placement parameters, the system achieves precise alignment without fixing positions in advance, balancing adaptability with operational ease.
2Adaptability or versatility
If video positions are fixed in advance, then device complexity is reduced, but adaptability to different instructional needs deteriorates
Solution Approach 1:
Users perform preliminary action by designating positions within each video that should be aligned. This preliminary designation enables the system to subsequently calculate and adjust optimal placement positions, providing adaptability for different instructional scenarios without requiring a complex pre-configured system.
Solution Approach 2:
The system implements dynamic adjustment of video placement positions based on user input. Rather than fixed positions, the placement is dynamically determined by the processor calculating optimal positions that align designated points, allowing flexibility for various instructional needs while maintaining manageable system complexity.
3Measurement precision
If multiple videos are displayed without alignment adjustment, then ease of operation is maintained, but measurement precision and instructional value deteriorate
Solution Approach 1:
The system replaces manual mechanical positioning with automated computational adjustment. The processor calculates optimal placement positions based on designated coordinates, achieving precise alignment automatically without requiring manual adjustment mechanisms, thus maintaining simplicity while improving precision.
Solution Approach 2:
The system introduces an intermediary computational process that translates user-designated positions into optimal placement positions. This intermediary calculation layer enables precise alignment by determining the mathematical relationship between designated positions and placement positions, achieving measurement precision without complicating user interaction.

AI summary
A video playback device includes a processor that executes a procedure. The procedure includes: for each of plural videos, receiving designations of positions in display regions of the videos; and adjusting a placement position in the display regions of the plural videos such that the positions designated for each of the plural videos are aligned at the same position in a vertical direction or a horizontal direction.
