Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices do not allow multiple users to simultaneously control different applications using separate remote controllers, leading to inefficiencies in multi-user scenarios.
Innovation Solution
A method and system for remotely controlling a display device that enables multiple users to control different applications using distinct remote controllers by transmitting identifiers and command signals, allowing each application to verify and execute commands based on stored identifiers, and utilizing a coupling table to manage remote controller interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single remote controller is used to control multiple applications, then the device complexity is reduced, but the productivity and ease of operation deteriorate because multiple users must wait sequentially to control their respective applications
Solution Approach 1:
The patent segments the control function by assigning unique identifiers to different remote controllers and linking them to specific applications. Each remote controller is coupled with a particular application through identifier matching, allowing simultaneous independent control of multiple applications by multiple users without interference.
2Device complexity
If a single remote controller is shared among multiple users, then the device complexity remains low, but the ease of operation worsens as users must wait their turn to control their desired application
Solution Approach 1:
The control system is segmented into multiple independent control channels, each identified by a unique identifier. Remote controllers are coupled with specific applications through identifier association, enabling each user to directly control their designated application without waiting for other users.
Solution Approach 2:
The patent introduces an identifier as an intermediary element that mediates between the remote controller and the application. The identifier serves as a key that links the remote controller to its coupled application, enabling automatic recognition and direct control without user intervention or waiting.
3Productivity
If multiple remote controllers are coupled with different applications, then the productivity and ease of operation improve for multi-user scenarios, but the device complexity increases due to identifier management and coupling mechanisms
Solution Approach 1:
The patent implements a universal identifier-based coupling mechanism that can be applied to any remote controller and application combination. The identifier system provides a multi-functional framework that handles remote controller recognition, application coupling, and command routing in a unified manner, making the system scalable to any number of users and applications.

AI summary
A display device and a method for remotely controlling the display device are disclosed. A controller executes a first application and a second application. A display displays a main window, which displays an execution screen of the executed first application, and a first sub window which displays an execution screen of the executed second application, on a screen. A receiver receives a focus switching signal from a first remote controller and a coupling signal containing an identifier from a second remote controller. The controller switches a focused window based on the received focus switching signal and implements coupling between the focused window and the second remote controller in response to the received coupling signal.
