Wireless Content Sharing Control via Coordinate Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Wi-Fi Display (WFD) standards limit content sharing to a single source device and a single sink device, with no control over what content is displayed, making it difficult for users to selectively share specific information or control the display on multiple devices.
Innovation Solution
A method and apparatus for controlling content sharing between devices in a wireless communication system, where a source device exchanges information and capability information with sink devices to establish connections and send specific display coordinates, allowing selective content sharing and control over what is displayed on sink devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire source device screen is mirrored onto the sink device screen, then complete content sharing is achieved, but the user cannot control what content is displayed
Solution Approach 1:
The patent segments the screen sharing functionality by introducing coordinate information that divides the source device screen into selectable regions. Instead of mirroring the entire screen, the system allows segmentation of display content through coordinate-based region selection, enabling users to share only specific portions of the screen while maintaining simple operation through automated coordinate transmission.
2Adaptability or versatility
If the WFD standard supports only a single source device and a single sink device, then the connection management is simple, but the user cannot share content with multiple devices simultaneously
Solution Approach 1:
The patent applies universality by enabling the source device to establish connections with multiple sink devices simultaneously. The system maintains a single connection management framework that can handle multiple device pairs, allowing the same source device to share content with multiple sink devices without requiring separate management protocols for each connection.
3Adaptability or versatility
If complete screen mirroring is performed without control, then all content is shared, but the user experience is degraded due to inability to select specific content
Solution Approach 1:
The patent implements local quality by transmitting coordinate information that specifies particular regions of the source device screen for sharing. Instead of uniform complete-screen mirroring, the system applies different quality levels to different screen regions, allowing users to select which specific content areas should be shared while maintaining high fidelity for selected regions and preventing information loss through precise coordinate-based region definition.
Data Source
AI summary
Methods and apparatuses are provided for sharing contents with a sink device in a wireless communication system. A first set of information is received from at least one sink device. A connection is established to the at least one sink device based on the first set of information. Capability information of the at least one sink device is received. A second set of information related to the capability information is sent to the at least one sink device.
