Parental Control System Using Facial Recognition and Program Substitution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing broadcasting signal receiving systems fail to effectively limit children's viewing of harmful programs and do not provide adequate control over switching to alternative, educationally advantageous programs, often requiring manual intervention and not ensuring that preferred channels are included in alternative selections.
Innovation Solution
A broadcasting signal receiving system that includes an image pick-up part for identifying viewers, a certifying part for verifying the identity of children, a harmful program condition setting part, and a viewing limit control part to automatically switch to pre-recorded useful programs when harmful content is detected, with customizable settings for time zones and priority ordering of alternative programs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If automatic channel switching is implemented when harmful programs are detected, then children are protected from harmful content, but the available alternative channels may be limited and not include the viewer's preferred channels
Solution Approach 1:
The system pre-stores multiple useful programs in an image recording and reproducing part before they are needed. When a harmful program is detected, the viewing limit control part immediately reproduces and displays one of these pre-stored useful programs without requiring any manual intervention or channel switching by the viewer. This preliminary preparation ensures both immediate protection from harmful content and availability of alternative content.
2Object-affected harmful factors
If manual channel switching is required when harmful programs are detected, then viewers can select alternative channels, but children must perform operations to switch to viewable channels which defeats the purpose of automatic protection
Solution Approach 1:
The system automatically detects when a harmful program is being viewed and self-corrects by switching to a pre-stored useful program without requiring any operation from the viewer. The viewing limit control part monitors the program content and autonomously performs the channel switching and program reproduction, making the protection mechanism truly automatic and eliminating the need for children to understand or operate the switching function.
3Object-affected harmful factors
If viewing restrictions are applied uniformly to all channels, then harmful content is blocked, but the viewer's taste preferences and favored channels are not considered
Solution Approach 1:
The system applies different viewing restrictions to different channels and programs based on their individual characteristics. The harmful program condition setting part allows parents to individually set harmful program conditions for each channel or program, and the viewing limit control part selectively applies restrictions only where needed. Useful programs are pre-stored in the image recording and reproducing part for specific channels, enabling localized protection that respects channel-specific content quality and viewer preferences.

AI summary
A broadcasting signal receiving system includes: an obtaining part for obtaining program information of a receiving program; a broadcasting signal receiving part for receiving a broadcasting signal; an image pick-up part for recording an image of a viewer; a certifying part for comparing the image of the face of the viewer recorded by the image pick-up part with the previously registered image of a face of an individual to certify the viewing individual; an image recording and reproducing part for recording and storing preset useful programs; a harmful program condition setting part for setting harmful program conditions; and a viewing limit control part, wherein when a certified result indicates an individual as an object whose viewing is limited and the receiving program corresponds to a set harmful program, the viewing limit control part reproduces and displays on a monitor screen the useful programs.
