Personal Storage Device Supplementary Information Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional synchronized data broadcast services restrict users from accessing supplementary information related to multimedia content after the broadcast is finished, and they do not efficiently utilize data resources for storing various data broadcast information.
Innovation Solution
An apparatus and personal storage device that connect user terminals with a network to receive and store supplementary information related to multimedia content, allowing access without time or location constraints, using a receiving unit to request and a control unit to transmit supplementary information from a database to a personal storage device, which can be based on a cloud service, and efficiently manage data storage by determining redundant information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synchronized data broadcast service is used, then data broadcast information coincides with A/V broadcast schedule, but user cannot access supplementary information after broadcast finishes
Solution Approach 1:
The system performs preliminary action by storing supplementary information in a database during the broadcast period and making it accessible through the personal storage device after the broadcast finishes. The control unit is configured to provide control such that the requested supplementary information is read from a database and transmitted to the personal storage device, enabling post-broadcast access.
Solution Approach 2:
The patent introduces a personal storage device as an intermediary between the user terminal and the supplementary information database. This intermediary stores and manages supplementary information locally, allowing users to access information without time constraints while the main broadcast system maintains its synchronized operation.
2Ease of operation
If all product information is stored without comparison, then user can access stored information, but data resources are not efficiently utilized
Solution Approach 1:
The system implements feedback by comparing continuously received product information with previously stored product information. The control unit determines whether product information is new based on this comparison, and only stores new information in the personal storage device, preventing redundant storage while maintaining accessibility.
Solution Approach 2:
The system performs self-service by automatically comparing incoming product information with stored information and making intelligent decisions about what to store. This eliminates the need for manual filtering and ensures that only necessary information is stored, optimizing data resource utilization.
