Wireless Screen Mirroring Pairing for Multiple Virtual Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current screen mirroring technologies lack the capability to support multiple virtual displays, limiting a single screen mirroring transmitter to pair with only one receiving device.
Innovation Solution
A wireless screen mirroring system comprising a router that functions as a controller or bridge, selecting and pairing a designated transmitting device with one or more receiving devices based on a configuration file, allowing simultaneous display of audiovisual data on multiple screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a screen mirroring transmitter uses extended display identification data (EDID) to create a virtual display, then it can communicate with the graphics card of a laptop, but it cannot support multiple virtual displays simultaneously
Solution Approach 1:
The system segments the screen mirroring function by separating the transmitter into multiple independent transmitting devices, each capable of creating one virtual display. This allows the system to support multiple virtual displays simultaneously while keeping each individual transmitter simple and manageable.
Solution Approach 2:
The router is designed with multi-functionality, serving as both a network routing device and a screen mirroring coordinator. It manages multiple transmitting devices and receiving devices, enabling a single router to handle multiple virtual displays without requiring complex changes to each transmitter.
2Adaptability or versatility
If a single transmitting device is limited to one virtual display, then the transmitter architecture remains simple, but the system cannot pair with multiple receiving devices
Solution Approach 1:
Multiple transmitting devices are merged into a coordinated system managed by the router. Each transmitting device maintains its simplicity while the router combines their capabilities to achieve multi-device screen mirroring functionality, resolving the contradiction between simple architecture and high productivity.
Solution Approach 2:
The router acts as an intermediary between transmitting devices and receiving devices. It manages the pairing relationships and coordinates data transmission, enabling a single transmitting device to effectively work with multiple receiving devices through the router's mediation without increasing the complexity of the transmitters themselves.
3Adaptability or versatility
If multiple transmitting devices are used to support multiple virtual displays, then multi-screen capability is achieved, but network load and complexity increase
Solution Approach 1:
The router performs preliminary pairing and configuration actions between transmitting and receiving devices. By establishing these connections in advance and managing them centrally, the system reduces the need for repeated negotiation and data routing, thereby lowering overall network load while supporting multiple screens.

AI summary
A wireless screen mirroring system is provided. The wireless screen mirroring system includes a first transmitting device and a second transmitting device, a first receiving device and a second receiving device, and a router. The router has at least one of the functions of a controller or a bridge. The router selects one of the first transmitting device and the second transmitting device as a designated transmitting device, and selects at least one of the first receiving device and the second receiving device as a designated receiving device based on a configuration file. The router pairs the designated transmitting device with the at least one designated receiving device. After pairing is completed, the designated transmitting device displays audiovisual data, transmits the audiovisual data to the at least one designated receiving device, and the at least one designated receiving device displays the audiovisual data.
