Video Quasi-Muting via Pre-Captured Clips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video conferencing technologies require significant network bandwidth for continuous virtual muting of video signals and can experience interruptions due to weak network signals, even when a participant wants to temporarily stop transmitting their live video without disrupting the conference.
Innovation Solution
A system and method for video conferencing that allows participants to selectively transmit a pre-recorded video clip instead of live video, reducing network loading and minimizing signal interference, while providing an option to alert others of the quasi-muting status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous virtual video transmission is used for video muting, then participants can maintain video presence without interruption, but network bandwidth consumption increases significantly
Solution Approach 1:
The system performs preliminary actions by capturing and storing video clips of the participant before muting occurs. These pre-captured clips are then transmitted instead of continuous live video, reducing bandwidth consumption while maintaining the appearance of continuous video presence.
Solution Approach 2:
Instead of transmitting the original continuous video stream, the system creates and transmits copies (pre-captured video clips) of the participant's video. These copies are sufficient to maintain the visual presence effect without requiring the full bandwidth of live continuous streaming.
2Loss of energy
If pre-recorded video clips are transmitted instead of live video, then network bandwidth usage is reduced, but video transmission may be interrupted by weak network signals
Solution Approach 1:
The system uses periodic action by transmitting video clips at intervals rather than continuous streaming. Multiple short clips are sent in sequence, creating a periodic transmission pattern that reduces overall bandwidth usage and is more resilient to network interruptions compared to continuous streaming.
3Loss of energy
If live video streaming is stopped to reduce network loading, then participants can perform tasks without disruption, but other participants may be unaware of the participant's status
Solution Approach 1:
The system implements feedback by notifying other participants when video muting is activated. This feedback mechanism ensures that other participants are aware of the status change, maintaining communication transparency while allowing the participant to reduce video transmission.

AI summary
A first communication is provided for use in a video conference session with a second communication portal via a network. The first communication portal may be configured to transmit live video stream of a participant through the second communication portal for presentation on a display thereof, and to a receive control instruction the participant to stop transmitting live video stream. The first communication portal may also be configured to selectively transmit a video clip showing the participant for playback on the display based on the received control instruction.
