Display Device Automatic Remote Control Setup via Memory Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current integrated remote control settings for display devices are inconvenient as they require manual reconfiguration every time the remote control is disconnected, and the device recognition rate is limited due to insufficient transmission of HDMI CEC/SPD information.
Innovation Solution
A display device with a memory to store device and setting information, and a controller to automatically set up the integrated remote control by matching acquired external device information with stored data, or by capturing video information to perform automatic settings even without network connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual integrated remote control setting is performed every time the remote control is disconnected, then the remote control can be reconnected, but the user convenience deteriorates due to repeated complex setting processes
Solution Approach 1:
The system performs preliminary actions by storing device information and setting parameters in advance during the initial integrated remote control setting. When the remote control is reconnected, the system retrieves and applies the stored settings automatically, eliminating the need for users to repeat the complex setting process. This preliminary storage of configuration data resolves the contradiction by preparing the system ahead of time for future reconnections.
Solution Approach 2:
The system creates a copy of the device information and setting parameters from the initial configuration and stores it in memory. Upon reconnection, this copied data is retrieved and applied to restore the integrated remote control functionality without requiring users to re-enter settings. This copying mechanism allows rapid restoration of settings, improving user convenience while minimizing time loss.
2Measurement precision
If automatic device recognition is implemented by collecting and updating external device data, then the device recognition rate improves, but the system complexity increases due to data collection and maintenance requirements
Solution Approach 1:
The system extracts only the essential device information (device type, connection status, and basic parameters) needed for integrated remote control functionality and stores this extracted data in a simplified format. By taking out only the necessary information rather than collecting comprehensive device data, the system achieves adequate device recognition without the complexity of maintaining extensive device databases.
Solution Approach 2:
The system performs self-service by automatically storing and retrieving device information without requiring external data collection or manual updates. The display device itself maintains the necessary configuration data, eliminating the need for complex external data collection systems and reducing overall system complexity while maintaining effective device recognition.
3Measurement precision
If HDMI CEC/SPD information transmission is enhanced to improve device identification, then the device recognition accuracy improves, but the compatibility requirements increase as more devices must support these protocols
Solution Approach 1:
The system achieves universal device identification by using multiple identification methods simultaneously - HDMI CEC/SPD information when available, and alternative identification methods when not available. This multi-functional approach allows the system to work with devices that support HDMI CEC/SPD while maintaining compatibility with devices that do not, thereby improving device identification accuracy without sacrificing broad protocol compatibility.
Solution Approach 2:
The system dynamically changes identification parameters based on device capabilities. When a device transmits HDMI CEC/SPD information, the system uses these parameters for identification. When such information is not available, the system switches to alternative parameters such as device connection status and basic device information. This parameter switching enables accurate identification of devices that support HDMI protocols while maintaining compatibility with devices that use different identification methods.
