Remote Control Locking Mechanism for Set-Top Box Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current parental lock systems are ineffective in preventing unauthorized access to set-top box functions, as users with access can still control the device, and voice-activated remotes may inadvertently receive unauthorized inputs, leading to unintended changes and charges.
Innovation Solution
A system that locks the remote-control device from sending signals to the set-top box until a predetermined code is entered, allowing users to specify codes for locking and unlocking based on user accounts and types of user input, thereby preventing unauthorized access and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If parental lock is implemented by preventing certain account from accessing functionality, then access control is improved, but unauthorized users can bypass by using authorized accounts
Solution Approach 1:
The patent segments the control mechanism by implementing remote control locking independent of user accounts. The remote control device itself is locked or unlocked, separate from account-based access controls. This allows the set-top box to be accessible through multiple accounts while the remote control remains secured, preventing bypass attempts using authorized accounts.
2Reliability
If password is required to access certain functionality, then access security is improved, but unauthorized users can still control set-top box through remote control
Solution Approach 1:
The patent introduces an intermediary authentication mechanism between the user and the set-top box functions. A passcode must be entered through the remote control to enable it to send signals. This intermediary step blocks unauthorized access even if someone obtains physical control of the remote, as they cannot bypass the passcode requirement.
3Reliability
If remote control is locked to prevent signal transmission, then unauthorized access is prevented, but legitimate user access is also blocked
Solution Approach 1:
The patent implements preliminary authentication before locking the remote control. The system receives a passcode through the remote control, validates it, and only then enables the remote to transmit signals. This preliminary action ensures that only authorized users can unlock the remote, while maintaining ease of operation for legitimate users who know the passcode.

AI summary
A system for locking a remote-control device blocks a remote-control device from sending signals related to user input until a code to unlock the remote-control device is received. The system for locking a remote-control device receives an indication that the remote-control device should be locked and locks the remote-control device. The system for locking a remote-control device receives user input and determines whether the user input included a predetermined code. Based on a determination that the user input included the predetermined code, the system for locking a remote-control device unlocks the remote-control device.
