Multimedia Playback Switching for Privacy-Safe Cross-Device Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia data projection methods between electronic devices often expose private information and require cumbersome manual settings, leading to inefficient and unfriendly user interactions.
Innovation Solution
A multimedia data playing method that allows seamless switching of multimedia data between devices by prompting users to select candidate devices for specific applications, enabling per-application or per-task granularity control, and displaying prompt interfaces to simplify the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If complete screen projection is implemented to utilize device characteristics, then display quality is improved, but information security deteriorates due to disclosure of private information
Solution Approach 1:
The patent segments the screen projection function into two distinct modes: complete screen projection for public content and selective application projection for private content. This segmentation allows users to choose the appropriate projection mode based on the nature of the content, thereby maintaining display quality while protecting information security.
Solution Approach 2:
The patent introduces dynamic switching capability between different projection modes. Users can dynamically switch between complete screen projection and selective application projection based on real-time needs, making the system adaptable to different scenarios and balancing display quality with information security.
2Object-affected harmful factors
If selective application projection is implemented to protect information security, then information security is improved, but operation complexity increases due to manual selection requirements
Solution Approach 1:
The patent implements a system where the device automatically manages projection settings based on application attributes. The system self-identifies which applications are suitable for projection and pre-configures them, eliminating the need for users to manually select and configure each application, thus reducing operation complexity while maintaining information security.
Solution Approach 2:
The patent performs preliminary configuration of projection settings for different applications in advance. The system pre-identifies public and private applications and sets up projection rules beforehand, so that during actual use, users only need to trigger projection without dealing with complex configuration, thereby simplifying operations.
3Measurement precision
If manual configuration is required for each projection to ensure precision, then projection accuracy is improved, but time consumption increases
Solution Approach 1:
The patent enables the system to automatically identify projection-uitable applications and configure projection parameters without user intervention. The device self-determines which applications to project and sets appropriate parameters, maintaining projection accuracy while eliminating the time users would spend on manual configuration.
Solution Approach 2:
The patent performs preliminary identification and configuration of projection settings for multiple applications in advance. By pre-processing these configurations, the system ensures projection accuracy is maintained while reducing the time required during actual projection operations, as users only need to initiate projection without reconfiguring settings.
