Video Conference Terminal Multi-Application Composite Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional conference video terminals are limited in their ability to present and interact with multiple applications during a conference, resulting in a poor user experience due to their single-function nature, where only video signals can be shared, and other applications like documents or PPTs cannot be displayed or interacted with.
Innovation Solution
A video conference method and system on an Android platform that allows for the simultaneous operation and display of multiple applications during a conference by performing specific video processing on video signals and interface images, enabling the transmission of these processed signals to other terminals, and allowing users to switch between different application views using preset instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional conference video terminal only views video signals transmitted by other video terminals, then the device complexity is low and the system is simple to operate, but the function is single and the user experience is not good
Solution Approach 1:
The terminal device is designed to perform multiple functions: it can both participate in video conferences and run other applications (word processors, PPT, browsers, etc.) simultaneously. The screen displays a composite image combining video conference content and other application content, making the terminal universal for both conference participation and document processing tasks
Solution Approach 2:
The patent merges the video conference function with other application functions into a single integrated display. The screen shows a composite image that combines the video conference interface with other application interfaces, allowing users to access multiple functions through one unified system rather than separate devices
2Adaptability or versatility
If a traditional conference video terminal can only view video signals, then the ease of operation is high, but the user experience is poor due to inability to present other applications
Solution Approach 1:
The screen is segmented to display different content in different regions. The composite image divides the display area to show both video conference content and other application content simultaneously, allowing users to view multiple types of information without complex switching operations
Solution Approach 2:
Instead of switching between applications in time (one at a time), the system uses the spatial dimension by displaying multiple applications simultaneously on the screen in different regions, adding a spatial dimension to the user interface
3Productivity
If the terminal simultaneously operates video conference application and other applications, then the productivity is improved, but the video processing complexity increases
Solution Approach 1:
The system creates a composite image that is a copy or representation of multiple application interfaces combined together. Instead of complex multi-screen setups, it generates a unified composite image copy that integrates video conference and other application content for display

AI summary
A video conference method, includes: during a conference, a first terminal operates a first application; performs first video processing on a video signal acquired by the first terminal and a video signal received from other terminals participating in the video conference, and displays the processed video signal; when the first terminal detects that one or more other applications on the first terminal are opened, the first terminal simultaneously operates the first application and other applications on the first terminal; and performs second video processing and third video processing on the video signal acquired by the first terminal, the video signal received from the other terminal participating in the video conference and an interface image(s) of the other applications on the first terminal, displays a video signal after the second video processing and transmits a video signal after the third video processing to the other terminal participating in the video conference.
