Screen Frame Transmission via 2D Bar Code Decoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in establishing a communication connection between transmitting and receiving devices for screen frame sharing due to the need for manual input of complex connection information, which is challenging for those unfamiliar with computer operations.
Innovation Solution
The system converts connection information into a 2D bar code, allowing the transmitting device to capture and decode it to establish a communication connection, simplifying the process for users by eliminating the need for manual IP address input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual input of connection information (IP address) is required to establish communication connection, then connection accuracy can be ensured, but user operation complexity increases significantly
Solution Approach 1:
The patent uses a 2D bar code as a visual copy of the connection information (IP address). Instead of requiring users to manually input the IP address, the system generates a 2D bar code that visually represents the connection information. The transmitting device captures this bar code image and automatically decodes it to obtain the IP address, thereby eliminating manual input while ensuring accurate transmission of connection information.
2Ease of operation
If automatic connection establishment through image capture is implemented, then user operation simplicity is improved, but system complexity increases due to additional components
Solution Approach 1:
The patent leverages the existing image capturing capabilities of mobile devices (camera or gallery) for a new purpose - capturing 2D bar codes for connection establishment. This multi-functional approach allows the device to use its existing imaging hardware not only for photography but also for automatic connection setup, thereby minimizing additional hardware requirements while achieving automatic connection establishment.
Solution Approach 2:
The patent replaces the manual mechanical input process (typing IP address using keyboard) with an optical system. The transmitting device uses its image capturing unit to optically scan the 2D bar code displayed on the receiving device, and the processing unit automatically decodes the visual information to extract connection details, eliminating the need for manual keyboard input.
3Productivity
If 2D bar code is used to represent connection information, then information transmission efficiency is improved, but compatibility with older devices may be reduced
Solution Approach 1:
The patent segments the connection information (IP address) into a structured 2D bar code format with distinct visual elements. The bar code encodes the IP address in a standardized format that can be systematically decoded. This segmentation allows efficient information transmission while maintaining a structured format that can be processed by compatible devices with appropriate decoding capabilities.

AI summary
A screen frame transmission system includes a receiving device and a transmitting device. The receiving device includes a display unit or an external display device for displaying a 2D bar code containing connection information. The transmitting device includes an image capturing unit for capturing an image of the 2D bar code. The transmitting device decodes the 2D bar code to obtain the connection information and establishes a communication connection with the receiving device therewith to transmit a screen frame, thereby simplifying operations of a user.
