Display Device Audio Isolation for Multi-Conference Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in conveniently participating in multiple video conferences simultaneously, as existing systems do not effectively manage audio outputs from multiple video conferences, leading to confusion and inefficient use of reference videos in both video and remote classes.
Innovation Solution
A display device with a speaker and controller that focuses on one video conference while converting the audio from unfocused conferences into text, allowing users to selectively hear desired voices and utilize text from unfocused conferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple video conferences are displayed simultaneously on a TV screen, then users can participate in multiple conferences at the same time, but audio output from multiple conferences causes confusion and makes it difficult to focus on a specific conference
Solution Approach 1:
The patent extracts the audio output function from the visual display system by introducing separate audio output devices (headphones, earphones, or external speakers) that can be selectively assigned to specific video conferences. This allows the audio focus to be separated from the visual multi-conference display, enabling users to concentrate on one conference's audio while viewing multiple conferences on screen without audio confusion
Solution Approach 2:
The patent introduces an audio output device as an intermediary between the multi-conference video system and the user's auditory perception. This intermediary allows selective audio routing where only the focused conference's audio is transmitted to the audio output device, while other conferences remain visually visible but audio-muted, thus mediating the conflict between multi-conference participation and audio focus
2Loss of information
If audio from all video conferences is output simultaneously through the speaker, then all conference voices are available, but this creates a confusing situation where multiple audio voices overlap
Solution Approach 1:
The patent applies local quality by assigning different audio output characteristics to different video conferences based on their focus status. The focused conference receives full audio output through the selected audio output device, while unfocused conferences have their audio either muted or routed differently. This creates a spatial and functional differentiation in audio quality across multiple conferences, allowing clear focus on one conference while maintaining visual awareness of others
3Area of stationary object
If the TV is used for video conferences, then the large screen supports multiple conferences visually, but the audio system cannot effectively manage multiple simultaneous voices
Solution Approach 1:
The patent merges the audio output functionality with the existing visual display system by integrating audio output device selection and control into the video conference interface. The same controller that manages visual display also manages audio routing, allowing users to select which conference's audio to hear through the connected audio output device while viewing multiple conferences on the TV screen. This combination simplifies the overall system architecture while solving the audio management problem

AI summary
A display device according to an embodiment of the present invention may comprise: an audio output unit; a display unit that displays a first image and a second image; and a control unit that, when the first image is focused from among the first image and the second image, outputs a first voice corresponding to the first image through the audio output unit, converts a second voice corresponding to an unfocused second image into text, and displays the converted text on the second image.
