Videoconference Terminal Display Flicker Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current videoconference systems experience screen flicker due to continuous updates of login states from other terminals, causing an unpleasant visual effect when terminals start receiving state information upon turning on.
Innovation Solution
The system suppresses the display of candidate terminal information until specific state information is received, delaying the display to reflect the actual state during this time, thereby reducing the frequency of updates and minimizing flicker.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display constantly refreshes to show updated login states of candidate terminals, then the information freshness is improved, but screen flicker occurs causing visual discomfort
Solution Approach 1:
The patent implements periodic action by controlling the display to update terminal state information only at specific intervals or under specific conditions rather than continuously. The display is suppressed from showing candidate terminal information during initial startup phase, then activated periodically after receiving specific state information, reducing flicker while maintaining information freshness.
Solution Approach 2:
The patent applies preliminary action by suppressing the display before the terminal starts receiving state information from other terminals. This preliminary suppression prevents flicker during the startup phase, and the display is activated only after the terminal has received sufficient state information to display meaningfully.
2Loss of time
If the display shows candidate terminal information immediately upon startup, then the user can access information faster, but the screen flickers due to frequent updates
Solution Approach 1:
The display is suppressed in advance during the startup phase before the terminal begins receiving state information. This preliminary suppression avoids the flicker problem while minimizing the delay in information access. The display is activated as soon as the terminal receives sufficient state information, balancing speed with visual stability.
3Loss of information
If the terminal receives and displays state information from all candidate terminals, then the completeness of information is improved, but the display flickers during the reception process
Solution Approach 1:
The patent implements periodic action by controlling the display to update information only after receiving specific state information from candidate terminals, rather than continuously updating during the reception process. This periodic update approach ensures information completeness while eliminating flicker by synchronizing display updates with stable data reception states.

AI summary
A transmission terminal, which displays information of a candidate counterpart transmission terminal through a display coupled to the transmission terminal, receives state information of the candidate counterpart transmission terminal through a communication network, suppresses the display from displaying the information of the candidate counterpart transmission terminal until specific state information of a specific transmission terminal is received, and causes the display to display the information of the candidate counterpart transmission terminal in a manner that reflects the state information of the candidate counterpart transmission terminal that is received by the transmission terminal during a display suppressing time in which the display is suppressed from displaying the information of the candidate counterpart transmission terminal.
