Display Interface Recognition Using Multi-Source Device Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face issues with misrecognition of external devices due to varying and arbitrary information transmission, leading to incorrect device identification and lack of verification or correction mechanisms, causing user inconvenience.
Innovation Solution
The display device employs a controller to recognize and calculate the accuracy of multiple pieces of information from external devices, setting the device with the highest recognition accuracy as the connection device, and allowing user selection when accuracies are equal, with prioritization based on device type and information type, and adjusting the connection device upon receiving new information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display device recognizes external devices based on information received from multiple transmission paths, then the device can identify various external devices, but misrecognition occurs due to arbitrary transmission timing and paths
Solution Approach 1:
The system performs preliminary actions by collecting all possible information from multiple transmission paths before making a recognition decision. It gathers device information through various interfaces (HDMI, USB, network) in advance, then processes this collected information to determine the most accurate device identification, avoiding hasty recognition based on incomplete data
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring information from multiple transmission paths and adjusting its recognition decisions. When new information arrives or conflicts are detected, the system re-evaluates device identity using updated data, ensuring recognition accuracy improves over time through iterative verification
2Measurement precision
If the display device manually inputs information about external devices, then recognition accuracy can be improved, but user convenience deteriorates due to manual input requirements
Solution Approach 1:
The external devices perform self-service by automatically transmitting their own identification information to the display device through multiple interfaces. The devices self-identify without requiring manual input from users, with the system autonomously collecting device names, types, and capability information through HDMI, USB, and network connections
Solution Approach 2:
The display device implements multi-functionality by using multiple information transmission paths (HDMI, USB, network protocols) simultaneously to gather device information. This universal approach allows the system to obtain accurate device identification through various channels, eliminating the need for manual input while maintaining high recognition accuracy
