Display Apparatus Multi-Terminal Control Signal Priority Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses lack a clear method for handling incompatible processing commands from multiple terminals, leading to unclear command processing and potential conflicts when prioritizing image display and control signals.
Innovation Solution
A control method and system that prioritize processing commands from terminals based on stored priority information, where the first control signal has higher priority than the second, ensuring that when processing is incompatible, the first control signal is executed preferentially.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display apparatus receives control signals from multiple terminals simultaneously, then the functionality and versatility of the system is improved, but conflicts and incompatibilities in processing commands arise
Solution Approach 1:
The display apparatus stores priority information in advance that defines the precedence relationship between control signals from different terminals. When multiple incompatible control signals are received, the apparatus refers to this pre-stored priority information to determine which signal to execute, thereby resolving conflicts without delay.
Solution Approach 2:
The system changes the parameter of signal priority by storing priority information that assigns different levels of importance to control signals from different terminals. This parameter change enables the apparatus to selectively execute specific control signals based on their predefined priority, resolving conflicts in multi-terminal control scenarios.
2Adaptability or versatility
If the display apparatus processes all control signals from multiple terminals, then the completeness of control functionality is improved, but processing conflicts and incompatibilities increase
Solution Approach 1:
The display apparatus pre-stores priority information that defines the processing sequence and precedence of control signals from different terminals. This preliminary action eliminates the need for complex real-time conflict resolution algorithms, simplifying the device complexity while maintaining complete control signal processing capability.
3Ease of operation
If the display apparatus uses proximity communication for terminal connection, then the ease of connection is improved, but the complexity of wireless transmission system increases
Solution Approach 1:
The display apparatus acts as an intermediary that receives control signals from multiple terminals via proximity communication and processes them according to stored priority information. This intermediary role simplifies the wireless transmission system by centralizing the conflict resolution function within the display apparatus itself.

AI summary
A control method for a display apparatus includes receiving a first control signal transmitted from a first terminal and a second control signal transmitted from a second terminal, storing priority information in which data showing that the second control signal has lower priority than the first control signal is recorded, and, when processing by the first control signal and processing by the second control signal are incompatible with each other, preferentially executing the processing by the first control signal according to the priority information.
