Display Device Remote Control Relay for Hidden Set-Top Boxes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in controlling external devices such as set-top boxes or image processing devices when they are moved, as the infrared receiver may be covered, leading to issues with remote controller functionality due to positional changes.
Innovation Solution
A display system that includes a display device and an image processing device, which transmits control signals between each other and adjusts the remote controller's operation mode from Bluetooth to infrared based on state changes, ensuring continuous control of external devices regardless of their position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If external devices are hidden in furniture to improve exterior appearance, then aesthetic appearance is improved, but remote controller control reliability deteriorates due to covered infrared receivers
Solution Approach 1:
The display device serves as an intermediary between the remote controller and the image processing device. It receives control signals from the remote controller via its exposed infrared receiver and transmits them to the hidden image processing device, enabling indirect control while maintaining both aesthetic appearance and control reliability
Solution Approach 2:
The patent replaces the direct infrared control mechanism (which requires line-of-sight to the infrared receiver) with an indirect control mechanism using the display device as a signal relay, substituting the physical infrared transmission path with an electronic signal transmission through the display device
2Reliability
If the display device is always externally exposed to receive remote controller signals, then remote control reliability is improved, but device complexity increases due to additional external components
Solution Approach 1:
The display device performs multiple functions: it serves as both the display output device and the control signal receiving device. By integrating the infrared receiver into the display device, the system eliminates the need for separate control devices, reducing overall system complexity while maintaining control reliability
3Adaptability or versatility
If external devices are moved to different positions for flexibility, then adaptability is improved, but control stability deteriorates as the infrared receiver may become covered
Solution Approach 1:
The system implements feedback by having the image processing device monitor whether it is receiving control signals from the display device. When control fails (indicating the infrared receiver is covered), the system provides feedback to guide the user to adjust the display device or image processing device positions until control is restored
Data Source
AI summary
A display system is disclosed. The present system comprises a display device and an image processing device, wherein the display device transmits a control signal for controlling an external image source device to the image processing device in response to a signal received from a remote controller, and the image processing device processes an image received from an image source device, transmits the processed image to the display device, and transmits the control signal received from the display device to the image source device. The image processing device identifies a state change of the display device in response to control signal transmission, and transmits a signal for changing an operation mode of the remote controller to the display device if no change is identified, and when the signal for changing the operation mode of the remote controller is received, the display device transmits the received signal to the remote controller.
