Transmission System Dynamic Screen Area Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing videoconference systems lack the ability for users to seamlessly switch between sharing the entire screen and specific areas of the screen with a communication partner, limiting user flexibility in content sharing.
Innovation Solution
A computer program that allows users to select and share either whole area or specific area display data with a communication partner by determining the appropriate resolution for transmission based on the display devices' capabilities and transmitting the acquired display data with the determined resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display data of a specific area is shared during videoconference, then the user can focus on particular content, but the user cannot switch to sharing the whole screen area
Solution Approach 1:
The patent implements dynamic switching capability that allows the system to transition between different display data sharing modes (whole screen vs. specific area) during videoconference operation. The switching unit enables users to change the sharing scope dynamically without requiring system reconfiguration, making the system adaptable to different presentation needs while maintaining operational simplicity.
2Manufacturing precision
If display data is transmitted with high resolution, then the display quality is improved, but the transmission bandwidth requirement increases
Solution Approach 1:
The patent applies local quality principle by transmitting display data at different resolution levels depending on the selected sharing mode. When a specific area is selected for sharing, the system transmits only that region's data at high resolution, while other areas are either excluded or transmitted at lower resolution. This approach maintains high display quality for the focused content while reducing overall transmission data volume compared to transmitting the entire screen at maximum resolution.

AI summary
A recording medium stores a program which, when executed by a computer, causes the computer to perform a process, the computer connected to a transmission terminal connected to a display device and connected to a second transmission terminal via a network, the process including: displaying an area of a program component on a screen of a second display device connected to the computer; receiving selection of one of display data of a whole area of the screen and display data of the area of the program component; acquiring the display data of the whole area or the area; receiving resolution information indicating a resolution of the display device from the transmission terminal; determining a resolution of the display data based on the resolution information and second resolution information indicating a second display device resolution; and transmitting the display data with the determined resolution to the transmission terminal.
