Solution Overview
Problem
Existing infrared transmission devices cannot accurately process repeat events, such as continuous button presses, from a single remote controller, leading to inconvenience in controlling both display devices and external electronic devices.
Innovation Solution
An infrared transmission device with a buffer to store request data and a determiner to identify repeat events, generating and transmitting corresponding infrared signals to process these events accurately, allowing a single remote controller to control both display and external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an infrared transmission device is used to control both display device and external electronic device with a single remote controller, then user convenience is improved, but the device cannot accurately process repeat events from the remote controller
Solution Approach 1:
The patent applies preliminary action by storing received request data in a buffer before processing. When a repeat event is detected (multiple identical request data stored in buffer), the system prepares the corresponding infrared signal in advance and transmits it to the external electronic device. This buffer-based preliminary storage mechanism enables accurate processing of repeat events while maintaining single remote controller operation.
Solution Approach 2:
The patent uses an intermediary mechanism by introducing a buffer as an intermediate storage component between the remote controller receiver and the infrared signal transmitter. The buffer acts as a mediator that temporarily holds request data, allowing the system to analyze patterns (detect repeat events) and generate appropriate infrared signals accordingly. This intermediary buffer resolves the contradiction by enabling reliable repeat event processing without requiring multiple remote controllers.
2Reliability
If multiple remote controllers are used to ensure accurate control, then control reliability is improved, but device complexity and user inconvenience increase
Solution Approach 1:
The patent applies universality by designing a single remote controller that can control both the display device and external electronic devices through the infrared transmission device. The buffer-based repeat event processing mechanism enables this single controller to reliably handle various control scenarios (normal events and repeat events) for multiple devices, eliminating the need for separate remote controllers while maintaining control accuracy.
Solution Approach 2:
The infrared transmission device acts as an intermediary between the single remote controller and multiple target devices (display device and external electronic device). The buffer within the transmission device mediates the control signals, storing and processing request data to generate appropriate infrared signals for different devices. This intermediary mechanism enables one controller to reliably control multiple devices without increasing complexity.

AI summary
Disclosed are a display device, and an infrared transmission device and a control method therefor. The disclosed infrared transmission device: determines whether a repeat event occurs, on the basis of the amount of request data stored in a buffer; and when a repeat event occurs, generates an infrared signal corresponding to the repeat event and transmits the infrared signal to a display device or an external electronic device.
