Automatic Content Transfer Based on Reproduction History
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in transferring and updating desired content from large-capacity HDDs to smaller capacity storage devices like flash memory cards without a cumbersome process, limiting the use of recorded content outside the home environment.
Innovation Solution
A content use system that includes a recording apparatus with storage, reproduction history acquisition, content extraction, and transfer means, and a portable reproducing apparatus with content acquisition, history generation, and transfer means, allowing for automatic selection and transfer of frequently used content based on usage history.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually transfer content from HDD to memory card, then desired content can be moved to portable device, but the process becomes troublesome and time-consuming
Solution Approach 1:
The system automatically identifies and transfers content that the user wants to move to the memory card without manual intervention. The recording apparatus autonomously monitors reproduction history, determines frequently accessed content, and performs transfers automatically, making the system serve itself rather than requiring user operation.
Solution Approach 2:
The system uses reproduction history information as feedback to automatically determine which content should be transferred. By monitoring how users actually use the content on the HDD, the system adapts its transfer decisions based on real usage patterns, creating a closed-loop control system that improves ease of operation.
2Quantity of substance
If users transfer only frequently used content to memory card, then storage space is optimized, but users cannot access updated content without re-transferring
Solution Approach 1:
The system performs preliminary transfers of content to the memory card based on predicted user needs from reproduction history. By proactively transferring content before the user explicitly requests it, the system ensures that updated content is already available on the portable device when needed, eliminating the need for re-transfer operations.
Solution Approach 2:
The transfer mechanism is made dynamic and adaptive rather than static. The system continuously monitors reproduction history and automatically adjusts which content is transferred and when, allowing the content selection to evolve with changing user preferences and usage patterns over time.
3Quantity of substance
If memory card capacity is increased to store more content, then more content can be accessed portably, but the device size and cost increase
Solution Approach 1:
The system extracts only the essential and frequently used content from the large-capacity HDD and transfers it to the smaller memory card. By selectively taking out only the necessary portion of content based on reproduction history analysis, the system maintains portable accessibility while avoiding the need for large-capacity memory cards.

AI summary
A recording apparatus includes a storage section that stores content data. The recording apparatus additionally includes a reproduction history information acquisition section that acquires reproduction history information about the content data from a portable reproducing apparatus. The recording apparatus further includes a content data extraction section that extracts one or more pieces of content data from the content data stored in the storage section in accordance with a reproduction start time included in the reproduction history information. The reproduction start time corresponds to a time at which a reproduction of the content data was started. The recording apparatus additionally includes a content data transfer section that transfers the extracted content data to the portable reproducing apparatus.
