Screen Mirroring via Cross-Protocol Instruction Bridging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current screen mirroring technologies, such as Miracast, require manual user intervention to enable wireless communication functions and often necessitate devices to be in the same local area network, complicating the process and reducing user convenience.
Innovation Solution
A method and apparatus that allow a transmitter device to determine a target receiver device supporting a second wireless communication manner and send a preset instruction via a first wireless communication manner, enabling the receiver to establish a mirror connection without manual user intervention or the need for a shared network, using protocols like Bluetooth and Miracast.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual user intervention is required to enable wireless communication functions, then connection reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The transmitter device automatically discovers available receiver devices and sends connection instructions without requiring manual user intervention to enable wireless functions. The system performs self-service by autonomously initiating the connection process while maintaining reliable protocol-based communication.
Solution Approach 2:
The transmitter device performs preliminary actions by automatically discovering receiver devices and preparing connection instructions before the user needs to use the screen mirroring function. This preliminary automatic setup eliminates the need for manual enabling of wireless communication functions at the moment of use.
2Stability of the object's composition
If devices must be in the same local area network, then connection stability is improved, but adaptability deteriorates
Solution Approach 1:
The patent introduces an intermediary instruction-sending mechanism that bridges devices on different networks. The transmitter sends connection instructions to the receiver through available communication channels, enabling cross-network connection while maintaining stable mirror connection establishment through protocol-based communication.
Solution Approach 2:
The connection process is segmented into independent stages: instruction sending phase and mirror connection establishment phase. This segmentation allows the devices to communicate through different network channels at different stages, enabling adaptability to various network configurations while maintaining connection stability during the actual mirroring process.
3Ease of operation
If automatic connection setup is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The transmitter device performs multiple functions using existing components: it uses its display to show receiver information, its communication module to send instructions, and its processing unit to manage the automatic connection process. This multi-functionality achieves automatic connection setup without requiring additional specialized hardware, thereby limiting the increase in device complexity.
4Measurement precision
If user intervention is required for network configuration, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent skips the time-consuming manual network configuration steps by implementing automatic discovery and connection initiation. The transmitter device automatically identifies receiver devices and establishes connection instructions, rushing through the setup process while maintaining accurate protocol-based communication to ensure proper network configuration.

AI summary
A method for minoring screen includes: determining a target receiver device to be screen-mirrored, where the target receiver device is a screen-mirrorable device supporting a second wireless communication manner; and sending a preset instruction to the target receiver device in a first wireless communication manner, where the preset instruction is used to instruct the target receiver device to establish a minor connection with the transmitter device in the second wireless communication manner.
