Application Control for Image Data Transfer to External Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment faces limitations in controlling the transfer of image data from predetermined applications, particularly those associated with push services, to external devices, leading to potential embarrassment due to the display of private notification messages on larger screens.
Innovation Solution
Implementing a method within user equipment to detect and restrict the transfer of image data from activated applications, especially those associated with push services, to external devices, by setting application control types as restricted or allowed based on user input, and registering external devices as restricted or allowed, thereby controlling the display of notification messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If image data from all applications is transferred to external device for display, then display quality and user experience on external device is improved, but privacy leakage and user embarrassment occur when notification messages are displayed publicly
Solution Approach 1:
The patent segments image data into two categories: general image data that can be transferred to external devices for display, and notification message image data that should be restricted. This segmentation allows the system to selectively transfer only appropriate content, resolving the contradiction between displaying quality content and preventing privacy leakage.
Solution Approach 2:
The patent applies different quality control rules to different types of image data based on their source applications. Notification message image data from push service applications is treated differently (restricted) compared to other image data (allowed for transfer). This local quality differentiation enables selective privacy protection while maintaining overall display functionality.
2Loss of information
If notification messages are displayed on external device, then information visibility is improved, but user distraction and embarrassment occur during presentations or public displays
Solution Approach 1:
The patent extracts notification message image data from the general stream of transferable image data. By identifying and separating notification messages based on their source applications (push service applications), the system removes potentially distracting content from external device display while preserving other useful image data transfer functionality.
Solution Approach 2:
The system introduces an intermediary control mechanism that sits between the image data source and the external device display. This intermediary (the user equipment's control system) filters image data based on application type, allowing beneficial information to pass through while blocking notification messages that would cause distraction during public displays.
3Adaptability or versatility
If user equipment is coupled to external device for enhanced display, then display capability is improved, but control complexity over image data transfer increases
Solution Approach 1:
The system implements self-service control by automatically identifying notification message image data based on the source application type without requiring manual user intervention. The user equipment's controller autonomously determines which image data to restrict based on pre-defined rules about push service applications, simplifying the user's task while maintaining sophisticated control capabilities.
Data Source
AI summary
Described embodiments provide a method and user equipment for restricting transferring of image data produced by a predetermined application to a coupled external device. The method may include detecting an activation of an application in a user equipment while the user equipment is coupled to an external device and determining whether image data produced by the activated application is transferred to the coupled external device. The determining may include restricting the produced image data of the activated application from being transferred to the coupled external device when an application control type of the activated application is a restricted application, otherwise, transferring the produced image data of the activated application to the coupled external device.
