Network Receiving Apparatus Age Limit Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no guarantee that a recorder in a network system detects viewing age limit information and requires the input of a registered personal identification number, leading to the possibility of children accessing content not intended for their age group when content is recorded and played back.
Innovation Solution
A network system where a receiving apparatus acquires viewing age limit compliance information from a recording and reproducing apparatus via UPnP protocols, determining whether to record content based on this information, ensuring that only compliant devices reproduce age-restricted content, with the recording and reproducing apparatus storing and delivering address information for compliance data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If content is uploaded to a recorder via network without verifying viewing age limit compliance, then recording convenience is improved, but content security deteriorates
Solution Approach 1:
The system performs preliminary verification of viewing age limit compliance information before content upload. The receiving apparatus checks whether the recorder has appropriate viewing age limit management capabilities prior to initiating the recording process, preventing unauthorized recording before it occurs.
Solution Approach 2:
The system implements feedback mechanisms where the receiving apparatus continuously monitors and verifies the recorder's viewing age limit compliance status. The recorder provides feedback about its compliance capabilities, and the receiving apparatus uses this feedback to control content upload decisions dynamically.
2Reliability
If viewing age limit verification is implemented before content upload, then content security is improved, but system complexity increases
Solution Approach 1:
The receiving apparatus acts as an intermediary between the content source and the recorder. It implements the verification logic and controls the upload process, shielding the user from complex verification procedures while ensuring security requirements are met.
Solution Approach 2:
The recorder provides self-service by maintaining and providing viewing age limit compliance information about itself. The system uses standardized protocols where devices automatically report their capabilities, reducing the need for manual configuration or complex external verification systems.
3Productivity
If recording proceeds without verifying recorder compliance, then productivity is improved, but harmful effects increase
Solution Approach 1:
The system applies preliminary anti-action by preventing content upload to non-compliant recorders before the harmful effect of unauthorized access can occur. The receiving apparatus proactively blocks uploads based on verification results, counteracting potential harm before it materializes.
