Dynamic Caption Hiding via Preconfigured Image Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for hiding captions in video images are limited to external captions and lack flexibility, as they do not allow for dynamic adjustment of hiding areas or time periods, and require manual editing of various file formats, which is cumbersome and inefficient.
Innovation Solution
A method and apparatus that acquire hiding area and time period information from users to display a preconfigured image over the specified area and time in both external and embedded captions, enabling flexible and real-time hiding of captions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual editing of external caption files is used to hide captions, then captions can be hidden, but the method is cumbersome and inefficient due to variety of file formats and inability to restore captions
Solution Approach 1:
The patent creates a copy of the original caption file and stores it separately. When captions need to be hidden, the system manages the caption display state without permanently modifying the original file. When restoration is needed, the system can revert to the original caption file or use the preserved copy, eliminating the need for manual re-editing and solving the problem of irreversible caption hiding.
Solution Approach 2:
The patent extracts the caption hiding function from manual file editing operations. By implementing a dedicated caption management module that automatically handles caption display and hiding based on user settings, the system removes the need for users to manually edit various caption file formats, significantly simplifying the operation process.
2Adaptability or versatility
If video playing software provides hiding setting option for captions, then captions can be hidden, but the method lacks flexibility in selecting time periods and partially hiding captions
Solution Approach 1:
The patent implements dynamic caption hiding by allowing users to set specific time periods for caption hiding and dynamically adjust hiding parameters during video playback. The system can switch between different caption hiding states (full hide, partial hide, show) based on user preferences and video content, providing flexible adaptation without complex manual operations.
Solution Approach 2:
The patent segments the caption hiding function into controllable parameters including time period selection, hiding area specification, and language-specific hiding. This allows users to hide captions selectively during specific time intervals, in specific regions of the screen, or for specific languages, providing fine-grained control while maintaining ease of operation through a unified interface.
3Adaptability or versatility
If external caption files are modified to hide sensitive vocabularies, then sensitive content can be shielded, but the method cannot be applied to embedded captions and requires different handling for various formats
Solution Approach 1:
The patent implements a universal caption management system that can handle both external caption files and embedded captions through a unified interface and processing mechanism. The system automatically detects the caption type and applies appropriate hiding operations, eliminating the need for separate handling of different caption formats and expanding compatibility across various caption types.
