Reproducing Apparatus Program for External Content Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio-visual equipment lacks efficient methods for managing and reproducing external contents downloaded via networks, particularly due to limited storage capacity and the need for manual deletion of downloaded content.
Innovation Solution
A program that associates specific information from a recording medium with medium identification information for efficient storage and retrieval, allowing users to download and reproduce external contents without manual deletion, even when multiple contents are downloaded or when different recording media are used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external contents are downloaded via network to a reproducing apparatus, then content availability and diversity are improved, but storage capacity is consumed and requires manual management
Solution Approach 1:
The reproducing apparatus automatically manages downloaded external contents by associating them with recording medium information and performing autonomous deletion when storage capacity is insufficient, eliminating the need for manual user intervention in content management
Solution Approach 2:
The system continuously monitors storage capacity and automatically deletes external contents when the storage limit is reached, creating a feedback loop that maintains storage balance without user intervention
2Adaptability or versatility
If multiple external contents are downloaded to the reproducing apparatus, then content selection and diversity are improved, but retrieval time and user effort increase
Solution Approach 1:
The system creates an associative link (copy of relationship) between external contents and recording medium information, enabling rapid retrieval through the link rather than searching through all downloaded contents
Solution Approach 2:
Recording medium information serves as an intermediary index that connects users to specific external contents, enabling efficient retrieval without directly searching through the entire content library
3Quantity of substance
If storage capacity is limited in the reproducing apparatus, then device portability and cost are improved, but content retention and accessibility worsen
Solution Approach 1:
The system automatically discards external contents when storage capacity is insufficient, recovering space for new downloads while maintaining the ability to retrieve discarded contents through the associative links when needed
Solution Approach 2:
The content library is made dynamic rather than static, allowing automatic addition and deletion of external contents based on storage capacity, ensuring the system adapts to storage constraints while maintaining functionality

AI summary
The problem to be solved is to make it possible to download via a network, efficiently manage, retrieve, and reproduce an external content associated with a content recorded on a recording medium. To solve the problem, a program is used which controls reproduction of information located on a recording medium and related information. The program includes the steps of: obtaining from the outside specific information associated with predetermined information recorded on a recording medium; and obtaining medium identification information located on a recording medium; wherein if the specific information has been obtained, a storage unit in a reproducing apparatus is controlled to associate the specific information with the medium identification information for storage.
