Communication Apparatus Dynamic Mode Switching for Screen Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current screen sharing technologies, such as Wi-Fi Display, face issues where highly confidential screens may be unintentionally displayed during mode transitions, and users cannot perform operations like selecting images after terminating direct mode, and data transmission cannot be switched between enabled and disabled states while specific applications are running.
Innovation Solution
A communication apparatus that switches between two modes: one for transmitting displayed image data and another for transmitting stored image data not displayed on the screen, with a determination unit to decide whether to continue or terminate data transmission after the second mode is terminated, allowing seamless transition to the first mode or termination of screen sharing based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If screen sharing is continued after direct mode termination, then screen sharing functionality is maintained, but confidential information may be unintentionally displayed
Solution Approach 1:
The patent implements dynamic mode switching between direct mode and mirroring mode based on transmission status. The system automatically transitions from direct mode to mirroring mode when direct mode terminates, allowing flexible adjustment of screen sharing behavior to prevent unintended confidential information display while maintaining screen sharing functionality.
2Object-affected harmful factors
If direct mode is terminated, then confidential information display is prevented, but users cannot perform operations like image selection
Solution Approach 1:
The system dynamically switches between direct mode and mirroring mode based on user needs. When direct mode terminates, the system can transition to mirroring mode which allows continued user operations like image selection while preventing unintended confidential information display, thus maintaining both security and operability.
3Device complexity
If data transmission is determined by application type, then transmission control is simplified, but switching between enabled/disabled states during application execution is impossible
Solution Approach 1:
The patent implements dynamic determination of data transmission status that can change during application execution. The system allows switching between enabled and disabled states based on real-time conditions rather than fixed application-type determination, enabling flexible adaptation while maintaining simple control mechanisms.

AI summary
A communication apparatus communicates with another communication apparatus and to transmit image data by one of: a first communication mode in which image data displayed on a display unit of the communication apparatus is transmitted to the another communication apparatus; and a second communication mode in which image data stored on the communication apparatus is transmitted to the another communication apparatus and is not displayed on the display unit, and determines whether to continue image data transmission. After image data is transmitted according to the second communication mode and the second communication mode is terminated, the communication apparatus continues transmitting the image data according to the first communication mode in the case that it is determined to continue the image data transmission, and terminates the image data transmission in the case that it is determined not to continue the image data transmission.
