Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling multi-screen configurations in video conferences are inflexible and require a PC console, limiting user convenience and flexibility in switching and managing multiple screens.
Innovation Solution
A method and system that utilize a multi-screen switching device to generate and send switching control messages to a Multi-Control Unit (MCU) or video conference terminals, allowing users to dynamically control the number and layout of screens through user inputs, such as adding, deleting, or transferring sub-screens, using a multi-touch display device or remote controller via wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a PC console is used to control multi-screen switching, then the control function is complete, but the operation flexibility and user convenience deteriorate
Solution Approach 1:
The patent extracts the multi-screen control function from the PC console and implements it directly in the video conference terminal. This allows the terminal to independently control its own multi-screen display without requiring external PC assistance, thereby improving ease of operation while maintaining functional completeness
Solution Approach 2:
The video conference terminal is enabled to autonomously perform multi-screen switching operations through its own control unit. The terminal serves itself by processing control instructions locally and managing its display configuration without external intervention, enhancing both convenience and operational independence
2Adaptability or versatility
If a PC console is used for multi-screen control, then centralized control is achieved, but the adaptability and flexibility of control methods deteriorate
Solution Approach 1:
The control architecture is segmented into independent functional modules within the terminal, including a control unit that processes switching instructions and a display unit that renders multi-screen content. This modular segmentation enables flexible control adaptations without requiring complex centralized coordination
Solution Approach 2:
The terminal's control unit dynamically adjusts multi-screen configurations based on received switching instructions, allowing real-time adaptation of display layouts. The system transitions from static PC-controlled configurations to dynamic terminal-autonomous configurations, enhancing control flexibility
3Productivity
If multi-screen control requires PC assistance, then control precision is maintained, but the response speed and operational efficiency deteriorate
Solution Approach 1:
The terminal pre-configures its multi-screen display capabilities and control interfaces during initialization, so that when switching instructions are received, the terminal can immediately execute the switching without requiring real-time PC processing. This preliminary preparation maintains control precision while significantly improving response speed
Solution Approach 2:
The control unit acts as an intermediary between the user interface and the display system, locally processing switching instructions and coordinating the multi-screen output. This local mediation eliminates the need for continuous PC involvement, improving operational efficiency while maintaining accurate control through the intermediary's coordinated management

AI summary
The present invention relates to multi-screen video image control. Disclosed are a method and system for switching the multi-screen on the video conference. The method comprises: a multi-screen switching device generates, according to a user input, a switch control message used for controlling the number of the multi-screen and a layout of the multi-screen, and sends the switching control message to an MCU or a video conference terminal; when the switching control message is sent to the MCU, the MCU switches, according to the switching control message, the number of the multi-screen or the layout of the multi-screen of each video conference terminal; and/or, when the switching control message is sent to the video conference terminal, the video conference terminal switches, according to the switching control message, the number of the multi-screen or the layout of the multi-screen of the video conference terminal.
