Audio Video Parameter Control via Signal Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current audio and video parameter adjustment interfaces on user terminals are cumbersome for non-technical users, requiring manual intervention and applying uniform settings to all content, which fails to adapt dynamically to the content's characteristics, leading to suboptimal viewing and listening experiences.
Innovation Solution
A method that analyzes audio and video signal characteristics in real-time to dynamically adjust parameters, such as brightness, contrast, and sound levels, synchronized with content rendering, using metadata and intra-content analysis to enhance immersion and comfort, while also considering user-specific criteria for personalized adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment interface is provided for audio and video parameters, then user can control settings, but operation becomes cumbersome and complex for non-technical users
Solution Approach 1:
The system automatically analyzes audio and video signal characteristics and adjusts parameters without requiring user interaction with complex interfaces. The terminal performs self-service by detecting content features and autonomously optimizing display and audio settings, eliminating the need for manual interface operation.
Solution Approach 2:
The manual mechanical adjustment interface is replaced with an automated electronic control system that uses signal analysis and processing algorithms. Instead of users navigating menus and adjusting sliders, the system electronically detects content characteristics and automatically configures parameters through software-based analysis.
2Adaptability or versatility
If uniform settings are applied to all content, then device complexity is reduced, but adaptability to different content characteristics deteriorates
Solution Approach 1:
The system applies different parameter settings to different portions of content based on local characteristics. By analyzing specific segments of audio and video signals and applying针对性 adjustments to each segment, the system achieves local optimization rather than uniform global settings, enhancing adaptability to diverse content types.
Solution Approach 2:
The parameter settings transition from static uniform values to dynamic content-adaptive values. The system continuously monitors signal characteristics and adjusts parameters in real-time according to the specific content being displayed, creating a dynamic adaptation mechanism that responds to varying content requirements.
3Adaptability or versatility
If automatic real-time adjustment is implemented, then adaptability to content improves, but device complexity and processing requirements increase
Solution Approach 1:
The system performs preliminary analysis of audio and video signal characteristics before full rendering occurs. By pre-detecting content features and preparing appropriate parameter settings in advance, the system reduces the complexity of real-time adjustments during actual content playback, as much of the analysis work is completed beforehand.
