Smart TV Remote Control via Mobile Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current smart televisions are difficult for minors and elderly users to control remotely, as they require users to be present at home to manage content and viewing time, leading to potential negative impacts on health due to unsuitable programming and operational complexity.
Innovation Solution
A mobile terminal system that establishes a link with a smart television, uses image processing to identify users, and remotely controls playback by setting allowable viewing times and content, incorporating a reward and punishment mechanism to manage viewing habits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users control smart television only when at home, then control simplicity is maintained, but remote control capability is lost
Solution Approach 1:
The patent introduces a mobile terminal as an intermediary device between the user and the smart television. The mobile terminal establishes a link with the television and transmits control commands remotely, allowing users to control the television from anywhere with network connectivity. This mediator approach maintains the simplicity of control through the familiar mobile device interface while enabling remote operation capability.
2Adaptability or versatility
If smart television has many functions, then functionality is improved, but ease of use for elderly deteriorates
Solution Approach 1:
The patent implements automatic audience identification through image processing that detects whether minors or elderly persons are watching. Based on this automatic identification, the system self-adjusts control modes: for elderly users, it simplifies operations and can remotely activate the television; for minors, it enforces time limits and content restrictions. This self-service approach eliminates the need for elderly users to navigate complex functions manually.
Solution Approach 2:
The system dynamically adapts its interface and control mechanisms based on the detected audience type. When elderly users are detected, the system switches to a simplified mode with larger interfaces and more intuitive controls. When minors are detected, it activates parental control features. This dynamic adaptation allows the television to maintain full functionality while adjusting its usability characteristics to match the user's needs.
3Adaptability or versatility
If minors watch television without remote monitoring, then viewing freedom is maintained, but health deterioration occurs
Solution Approach 1:
The patent implements a feedback mechanism where the mobile terminal continuously monitors the television's state, including current program content and viewing duration. When predefined thresholds are exceeded (such as maximum viewing time or inappropriate content detection), the system automatically provides feedback by sending control commands to adjust or terminate viewing. This feedback loop maintains minors' viewing freedom within healthy boundaries while preventing excessive or harmful viewing habits.
4Adaptability or versatility
If television content is not restricted, then content variety is improved, but suitability for minors deteriorates
Solution Approach 1:
The patent employs preliminary action by pre-establishing parental control settings and content restrictions through the mobile terminal before minors begin watching. Parents can pre-configure allowed content categories, time limits, and viewing schedules. The system then automatically enforces these pre-set restrictions during viewing, allowing minors to access a variety of pre-approved content while blocking unsuitable programs. This preliminary configuration approach maintains content variety within safe boundaries without requiring real-time intervention.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables remote monitoring and control of smart television usage by minors and elderly users, preventing excessive viewing and ensuring suitable content, thereby reducing health risks and simplifying operation for the elderly.
Implementation Method 1
receiving, by the mobile terminal an image located in front of the smart television and transmitted by the smart television, extracting facial features in the image according to an image processing algorithm
Data Source
AI summary
A method and a system for remotely controlling a smart television based on a mobile terminal and the mobile terminal are disclosed. The method includes: detecting a state of the smart television every predetermined time interval by the mobile terminal, and receiving a command input from a user to acquire a type of an audience watching the smart television; determining whether a current playing time, a playing content and a playing duration conform to conditions preset by a user, when the audience watching the smart television is a minor; and detecting whether the smart television is in a turned-on state when the audience watching the smart television is an older person.
