Image-Linked Speaker Volume Control for Video Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often struggle to identify and control the volume levels for individual speakers in video recordings, leading to suboptimal user experience in video capturing and playback.
Innovation Solution
An electronic device equipped with processors and memory that can identify multiple voice signals and speakers in content, allowing for individual volume control through user inputs, adjusting volumes for specific speakers while maintaining others.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual volume control for each speaker is implemented, then user convenience and video quality are improved, but device complexity increases
Solution Approach 1:
The audio signal is segmented into multiple independent voice signals, each corresponding to a specific speaker. This segmentation enables individual volume control for each speaker while maintaining the overall system through modular processing of separate audio streams
Solution Approach 2:
Voice activity detection (VAD) technology serves as an intermediary mechanism that automatically identifies and separates different speakers' signals. This intermediary process simplifies the user interface by providing automatic speaker differentiation, reducing the need for complex manual configuration while enabling precise individual volume control
2Measurement precision
If multiple voice signals are identified and separated, then precise volume control is achieved, but processing time and computational resources increase
Solution Approach 1:
Voice activity detection is performed preliminarily to identify and separate different speakers' signals before the main processing occurs. This preliminary segmentation of audio signals into speaker-specific streams enables faster subsequent processing and reduces the computational burden during volume adjustment operations
