Wireless Display Data Mirroring Using Application Description Format
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Wi-Fi display technologies provide a poor user experience due to limited screen size on mobile devices and lack of intelligence in mirroring content to larger displays, resulting in an inadequate viewing experience for users.
Innovation Solution
A method and system for enhanced data mirroring in wireless communication systems, where a source device transmits application data and display information to a sink device, allowing for intelligent display of content on larger screens, including support for enhanced display applications and virtual screen mirroring, using application description format (ADF) information and parameters like 'Display_Enhanced_Apps_Support' and 'Max_No_Of_Display_Enhanced_Apps' to determine capabilities and format data for optimal display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If content is mirrored on mobile device display, then content can be viewed, but display size is limited and user experience is poor
Solution Approach 1:
The patent segments the display functionality by separating the source device (mobile phone) from the sink device (external display). The mobile device transmits content to the external display, allowing the user to interact with the content on the larger external screen while maintaining the convenience of mobile device operation. This segmentation resolves the contradiction by providing a larger display area without compromising the ease of operation.
Solution Approach 2:
The patent introduces an intermediary mechanism (wireless display transmission system) between the mobile device and the external display. This intermediary enables content to be transmitted from the mobile device to the external display, allowing the user to view content on a larger screen while maintaining the ease of operation through the mobile device interface. The intermediary resolves the contradiction by bridging the gap between limited mobile display and desired large display experience.
2Area of stationary object
If content is mirrored to larger display, then display area increases, but mirroring lacks intelligence and user experience deteriorates
Solution Approach 1:
The patent applies local quality by enabling selective content transmission based on the capabilities and requirements of the sink device. The system determines whether to transmit full-screen content, partial content, or enhanced application data based on the specific sink device type and user needs. This localized adaptation resolves the contradiction by providing intelligent mirroring that tailors content delivery to the specific display device and user context.
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting transmission parameters based on sink device capabilities. The system modifies content format, resolution, and transmission mode according to the detected sink device characteristics. This parameter adaptation enables intelligent mirroring that enhances user experience while utilizing the larger display area effectively.
3Loss of information
If application data is displayed on mobile device, then data is accessible, but detailed application information cannot be fully viewed due to limited screen size
Solution Approach 1:
The patent transitions from two-dimensional display (mobile screen) to three-dimensional interaction by enabling the external display to show detailed application information that cannot be fully viewed on the mobile device. The system transmits enhanced application data to the external display, allowing users to access detailed information in a new spatial dimension. This resolves the contradiction by eliminating information loss while utilizing the additional display area.
Solution Approach 2:
The patent applies preliminary action by pre-processing and selecting which application data to transmit to the external display. The system determines in advance which detailed application information should be displayed on the external screen based on user interaction patterns and device capabilities. This preliminary selection ensures that the most relevant information is transmitted, preventing information loss while efficiently utilizing the external display area.
