Unified Remote Control for Multi-Source Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices cannot simultaneously control multiple source devices, such as TVs and mobile terminals, using a single remote control, leading to inconvenience when mirroring content from mobile terminals.
Innovation Solution
A display device with a control unit that receives control activation requests from a remote control device, allowing it to activate and control operations of connected source devices, including mobile terminals, enabling unified control through a remote control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display device is connected to multiple source devices for displaying multiple contents, then the display capability and content variety are improved, but the control complexity increases and unified control becomes difficult
Solution Approach 1:
The patent merges the control functions for multiple source devices into a single remote control device. The remote control can selectively control different source devices (TV, mobile terminal, etc.) that are connected to the display device, providing unified control without requiring separate remote controls for each device.
Solution Approach 2:
The remote control device is designed with universal control capability to manage multiple types of source devices. It can activate and control different devices based on selection signals, making a single remote control suitable for diverse equipment including mirroring devices and traditional AV devices.
2Ease of operation
If separate remote control devices are used for each source device, then each device can be controlled independently, but the number of remote controls increases and operation convenience decreases
Solution Approach 1:
The patent combines multiple control functions into a single remote control device that can manage multiple source devices. Instead of using separate remotes for TV, mobile terminal, and other devices, one unified remote control provides selective control over all connected devices.
Solution Approach 2:
The display device acts as an intermediary between the single remote control and multiple source devices. The remote control sends selection signals to the display device, which then activates and transmits control signals to the appropriate source device, simplifying the control architecture.
3Adaptability or versatility
If mirroring technology is used to display mobile terminal screen, then content display flexibility is improved, but the ability to control mobile terminal via remote control is lost
Solution Approach 1:
The remote control device is designed to universally control both traditional source devices and mirroring devices. When a mobile terminal is connected for screen mirroring, the remote control can still activate and control the mobile terminal through the display device, maintaining control capability across different display modes.
Solution Approach 2:
The display device serves as a mediator that enables control of mirroring devices through the remote control. It receives control signals intended for the mobile terminal and forwards them appropriately, allowing unified control even when the mobile terminal is in mirroring mode.

AI summary
A display device includes a display unit configured to display a plurality of pieces of content received from a plurality of source devices connected to the display device; and a control unit configured to receive a control activation request for a first source device of the plurality of source devices from a remote control device, activate control of the first source device in response to the received control activation request, and control an operation of the first source device in response to the signal received from the remote control device.
