Video Conference Receiver Standby Screen Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conventional video conference systems, when the transmitter device stops screen sharing, the receiver device remains in a standby mode and continues to output a standby screen to the video conference screen management device, occupying part of the video conference system screen.
Innovation Solution
The video conference system includes a receiver device that wirelessly connects to a transmitter device and a video conference screen management device, where the receiver device does not output the standby screen to the management device when the transmitter device stops screen sharing, using physical buttons, ports, image processing units, and signal exchanges to determine connection states and manage screen outputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the receiver device continues to output standby screen to the video conference screen management device when the transmitter device stops screen sharing, then the receiver device maintains its standby mode operation, but the video conference system screen is occupied by the standby screen
Solution Approach 1:
The patent extracts the standby screen output function from the receiver device when connected to the video conference screen management device. The receiver device detects the connection state and selectively suppresses standby screen output only to the management device while maintaining standby functionality for other displays, thereby removing the harmful effect of screen occupation without compromising the standby mode operation.
2Area of stationary object
If the receiver device stops outputting standby screen when connected to the video conference screen management device, then the video conference system screen is freed from standby screen occupation, but the receiver device must accurately detect connection state to avoid improper behavior
Solution Approach 1:
The patent implements a feedback mechanism where the receiver device continuously detects its connection state with the video conference screen management device and adjusts its standby screen output behavior accordingly. The detection module monitors connection status and provides feedback to the control module, which then dynamically controls whether to suppress standby screen output, enabling adaptive behavior based on real-time connection conditions.
3Ease of operation
If the receiver device maintains standby screen output for all displays, then the standby functionality is simple to implement, but the display quality is degraded due to standby screen occupation
Solution Approach 1:
The patent applies local quality by differentiating the standby screen output behavior for different display destinations. The receiver device maintains standard standby screen output for local displays or displays not connected to the video conference system, while selectively suppressing standby screen output only for the video conference screen management device. This localized differentiation preserves display quality in critical areas without complicating the overall standby functionality.
Data Source
AI summary
A video conference system is disclosed. The video conference system includes at least one transmitter device and a receiver device. The transmitter device is connected to an information processing device. The receiver device and the transmitter device are wirelessly connected. The receiver device wirelessly receives a video data related to the information processing device transmitted by the transmitter device. When the receiver device triggers a standby screen and the receiver device is connected to a video conference screen management device, the receiver device does not output the standby screen to the video conference screen management device.
