Audiovisual Control System for Multiuser Audio Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments where multiple users have differing television viewing preferences, existing systems often force viewers to listen to unwanted audio due to simultaneous broadcasting of competing audio streams, leading to an unsatisfactory viewing experience.
Innovation Solution
An audiovisual control system that allows individual users to select and control their audio feeds by using a receiving device to determine which users are viewing specific video feeds, enabling each user to change their audio output independently without affecting others, using headphone devices with buttons, accelerometers, or gaze-tracking cameras to manage multiple video streams and audio feeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple televisions are used to display different video feeds for multiple users, then user viewing satisfaction is improved, but audio interference occurs where all users are forced to listen to the same audio stream
Solution Approach 1:
The audio output is segmented and distributed to different users based on their selected video feeds. Each user receives a dedicated audio stream through individual headphone devices, separating the audio experience from the shared visual display. This allows multiple users to watch different content simultaneously without audio interference.
Solution Approach 2:
A receiving device acts as an intermediary between the video feeds and users' headphone devices. This mediator receives video feed selections from multiple users, determines which users are viewing each feed, and routes the corresponding audio streams to the appropriate headphone devices, thereby resolving the audio interference problem.
2Ease of operation
If a user changes their selected video feed, then individual content control is improved, but other users' viewing experience is disrupted when they are also watching the same feed
Solution Approach 1:
The system implements feedback by monitoring which users are currently viewing each video feed. When a user attempts to change their selected feed, the system checks whether other users are watching the same feed and provides feedback by either allowing the change (if no other users are viewing) or preventing it (if other users are viewing), thereby maintaining viewing experience stability while enabling individual control when appropriate.
3Ease of operation
If audio is broadcast aloud for multiple television channels, then audio accessibility is improved, but users are forced to listen to unwanted audio content
Solution Approach 1:
Instead of broadcasting audio universally to all users, the system applies local quality by providing customized audio streams to each user based on their individual video feed selection. Each user receives audio content that is locally tailored to their viewing choice, eliminating exposure to unwanted audio from other channels while maintaining audio accessibility.

AI summary
Various audiovisual presentation arrangements are described. In some embodiments, a headset is configured to output audio to a user. A television receiver may be configured to output a plurality of video feeds for simultaneous presentation by a display device. Each video feed of the plurality of video feeds may be displayed in a different display region of the display device. The television receiver may receive a command indicative of a video feed of the plurality of videos feeds that the user is viewing on the display device. Based on the command, the television receiver may output, to the headset, an audio feed that corresponds to the video feed the user is viewing.
