Screen Mirroring via Wireless Link for Instant Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current screen mirroring technologies for mobile terminals are complex and lack flexibility, making it inconvenient to display multimedia content from small mobile device screens to larger displays.
Innovation Solution
A method for screen mirroring on mobile terminals that simplifies operations by establishing direct connections through wireless technologies like hotspot, Bluetooth, or infrared, allowing for instant transmission of multimedia files or image signals based on user commands, and adapts to the computing and storage capabilities of the receiving device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If current screen mirroring technology is used, then screen content can be displayed on another device, but the operation process becomes complex and flexibility is reduced
Solution Approach 1:
The patent extracts and separates the screen mirroring function into an independent system consisting of a control end and a display end. The control end includes a screen capture module that independently captures screen content, while the display end independently receives and displays the content. This separation eliminates the need for complex integrated processing in existing systems, thereby simplifying operations while maintaining functionality.
Solution Approach 2:
The patent creates a universal screen mirroring system that can work across different device types and operating systems. The control end can be any device with screen capture capability, while the display end can be any device with screen display capability. This multi-functional design allows the system to adapt to various scenarios without requiring device-specific complex configurations, thus improving ease of operation.
2Speed
If screen mirroring is implemented, then content can be displayed on larger screens, but signal delay increases and resources are consumed
Solution Approach 1:
The patent implements preliminary action by having the control end continuously capture and prepare screen content in advance before actual display needs arise. The screen capture module continuously obtains current screen content and maintains it ready for transmission, so when the display end requests content, it can be transmitted immediately without processing delays, thus reducing signal delay while maintaining fast transmission speed.

AI summary
A screen mirroring method includes: establishing a connection to at least one second terminal device(S21); receiving an operation command(S22); transmitting multimedia files or image signals of the mobile terminals to a corresponding second terminal device according to the operation command, to make the multimedia files or the image signals be instantly displayed on the corresponding second screen terminal(S23). A screen mirroring apparatus(500) and a mobile terminal(10) are provided further. According to the screen mirroring method and the apparatus(500) and the mobile terminal(10), the multimedia files or the image signals of the mobile terminal are transmitted to the corresponding second screen terminal due to the received operation command, so that the multimedia files or the image signals are instantly displayed on the corresponding second screen terminal, which makes the operation be simple and have good flexibility.
