Content Management Unit Selective Duplicate Purchase Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a multi-user home environment, existing content distribution systems fail to selectively notify users about duplicate purchases, especially when the content may contain harmful or undesired information, lacking the ability to filter notifications based on user preferences or content type.
Innovation Solution
A recording and reproducing apparatus that includes an input unit for setting notification preferences for each content or genre, a content management unit to determine and manage purchase information, and an output unit to present notifications only to authorized users, allowing for selective prevention of duplicate purchases and information filtering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If duplicate purchase notification is provided to all users, then users can be informed about existing content purchases, but harmful or undesired information may be exposed to unauthorized users
Solution Approach 1:
The notification system applies different quality levels of information disclosure to different user groups. Authorized users receive complete purchase information including potentially harmful content details, while unauthorized users receive filtered notifications that exclude such information. This resolves the contradiction by allowing full information transparency where needed while preventing harmful exposure where not needed.
Solution Approach 2:
The notification control unit acts as an intermediary between the purchase information storage and the output notification system. It filters and selectively discloses information based on user authorization status, preventing direct exposure of harmful information to unauthorized users while still maintaining the integrity of the purchase information database.
2Adaptability or versatility
If notification preferences are set for each user, then information filtering is improved, but system complexity increases
Solution Approach 1:
The notification control unit performs multiple functions: it stores user authorization information, determines notification preferences, filters purchase information, and controls output notifications. By consolidating these diverse functions into a single multi-functional unit, the system achieves high adaptability without proportionally increasing overall system complexity.
3Measurement precision
If all purchase information is stored centrally, then duplicate detection is accurate, but user privacy and security are compromised
Solution Approach 1:
The system stores complete purchase information centrally for accurate duplicate detection, but applies local quality control by selectively disclosing only appropriate portions of this information to different users. The notification control unit ensures that while the central storage maintains full data integrity for accurate detection, the disclosure to individual users is tailored to their authorization level, preventing security risks.

AI summary
A recording and reproducing apparatus for content detects that the same-already purchased content is present when a user newly purchases a content, and determines, based on information in which a user who previously purchases a content sets whether to open the purchase, whether a message to the effect that the content is purchased in duplicate is displayed to the user who newly purchases the content.
