TV Audio Processing Visual Feedback for Quality Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers find it difficult to evaluate audio quality in TVs as it can only be assessed through listening, lacking a visual representation for comparison.
Innovation Solution
A TV audio processing method that determines specific events to display an audio quality setting state, improves audio signals, and plays back both original and enhanced audio signals to visually demonstrate improved audio quality, allowing users to assess audio performance more effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If audio quality improvement operation is performed, then audio quality is improved, but device complexity increases
Solution Approach 1:
The audio processing is divided into separate modules: audio signal processing unit for quality improvement, determination unit for event detection, and display unit for visual feedback. This segmentation allows the complex audio processing to be isolated and optimized independently without affecting the entire system.
Solution Approach 2:
A determination unit acts as an intermediary between the audio signal processing and the display unit. It receives audio signals, determines when quality improvement should be applied, and triggers appropriate visual display, thereby mediating between processing complexity and user perception.
2Ease of operation
If audio quality setting state is displayed, then ease of evaluation is improved, but device complexity increases
Solution Approach 1:
The display unit utilizes visual changes (analogous to color changes in TRIZ) to represent different audio quality states. By displaying distinct visual indicators for original and improved audio quality settings, the system provides intuitive feedback without adding complex interaction mechanisms.
Solution Approach 2:
The patent replaces the purely auditory evaluation mechanism with a visual display mechanism. Instead of relying solely on users to listen and compare audio qualities, the system uses visual indicators to represent audio quality states, making evaluation more accessible and easier to understand.
3Ease of operation
If both original and improved audio signals are played back, then ease of evaluation is improved, but loss of time increases
Solution Approach 1:
The audio signals are played back in a periodic sequence, alternating between original and improved audio signals. This periodic presentation allows users to compare the two qualities systematically without requiring simultaneous playback, thereby reducing the time needed for evaluation while maintaining ease of comparison.

AI summary
A television (TV) includes an audio signal processing unit which processes a audio signal, a display unit which displays an audio quality setting state, a determination unit which determines if an event for checking audio quality has occurred, and a control unit which controls the display unit to display an audio quality setting state showing improved audio quality if the event has occurred.
