Subtitle Control System for Audio Conflict Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumer electronics devices, such as smartphones and tablets, face issues with managing audio playback functions when multiple applications request access simultaneously, leading to unexpected and undesirable behavior, including audio signal conflicts and the need for users to navigate complex interfaces to access subtitles, which can discourage usage and waste resources.
Innovation Solution
A subtitle control system that automatically controls subtitle presentation based on volume controls and access policies, allowing seamless viewing of video content with subtitles while listening to audio from another application, reducing user burden and resource usage by defaulting to subtitle presentation and allowing users to override as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device grants audio playback access to one application at a time, then audio signal conflicts are avoided, but the interface complexity increases and user experience deteriorates when multiple applications need simultaneous access
Solution Approach 1:
The patent introduces a subtitle control system as an intermediary layer between the audio playback function and multiple applications. This mediator detects when subtitles should be presented and automatically manages the audio playback access, allowing multiple applications to coexist without direct conflicts while maintaining simple user interaction through automatic subtitle-based control
2Ease of operation
If the device requires users to navigate complex interfaces to access subtitles, then subtitle access control is precise, but user burden increases and resource consumption increases
Solution Approach 1:
The subtitle control system operates autonomously by detecting audio playback states and automatically presenting subtitles without requiring user navigation or input. The system serves itself by monitoring system states and making decisions about when to display subtitles, eliminating the need for users to manually access subtitle settings
Solution Approach 2:
The system prepares and presents subtitles in advance based on detected audio playback conditions, so that subtitles are already available and displayed when needed, rather than requiring users to search for and activate them after the fact
3Adaptability or versatility
If the device allows multiple applications to request audio playback simultaneously, then application versatility is improved, but audio signal conflicts and unexpected behavior occur
Solution Approach 1:
The subtitle control system acts as a mediator that receives requests from multiple applications but manages audio playback access through a controlled process. It detects when subtitles should be presented and coordinates audio access accordingly, allowing multiple applications to be supported while maintaining stable audio playback through centralized control
