TV Input Device Account Mapping for Secure App Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current TVs do not efficiently manage user authentication for external applications and input devices, requiring users to go through individual account authentication processes due to differing security protocols, causing inconvenience.
Innovation Solution
A TV system that includes a display module, communicator, and controller to establish Bluetooth connections with input devices, allowing for automatic account mapping, encrypted storage, and personalized device management, including a frequently used application list and gesture-based control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual account authentication is required for each application, then security is improved, but user convenience deteriorates
Solution Approach 1:
The system performs preliminary account authentication when the input device is first connected or when authentication is required. The authenticated account information is stored in association with the input device, so that subsequent applications can automatically use the pre-authenticated account without requiring re-authentication, thus improving convenience while maintaining security
Solution Approach 2:
The system enables self-service authentication where the input device itself is used to authenticate account information automatically. Once authenticated, the system automatically maps account information to the input device and uses it for subsequent applications, eliminating the need for manual re-authentication and improving user convenience
2Ease of operation
If automatic account mapping is implemented, then user convenience is improved, but security management complexity increases
Solution Approach 1:
The system introduces an intermediary mechanism where the input device serves as a mediator between the user and the authentication system. The input device is used to input account information, which is then automatically mapped and stored in association with the device. This intermediary approach simplifies the user experience while providing a structured way to manage security credentials
Solution Approach 2:
The system creates a copy of the account information mapping relationship between the input device and the authenticated account. This mapping is stored and can be automatically retrieved and used for subsequent applications, eliminating the need for re-authentication while maintaining security through encrypted storage
3Ease of operation
If input device name can be changed, then user personalization is improved, but device identification complexity increases
Solution Approach 1:
The system allows the input device name to be dynamic and changeable. Users can change the device name through the remote control, and the system updates the name in the stored mapping information. This dynamic naming capability enables personalization while the system maintains internal identification through the mapping relationship between the device and authenticated account

AI summary
One embodiment of the present invention provides a TV comprising: a display module for outputting content; a communication unit for receiving a control signal of a remote control device; and a control unit. The control unit carries out Bluetooth connection with an input device, and if a first control signal for changing the name of the input device is received from the remote control device, changes the name of the input device.
