Replay Device Search Information Storage for Multi-Server DLNA Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in easily searching and replaying desired contents across multiple server devices in the Digital Living Network Alliance (DNLA) system, as they need to repeatedly select and specify classification categories and properties, especially when the desired content is stored on a different server device.
Innovation Solution
A replay device with server device selection, search information specification, and cumulative storage of search information allows automatic specification of classification categories and properties when switching between server devices, ensuring seamless content searching and replaying without the need for repeated designation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the user repeatedly selects different server devices to search for contents, then the user can find desired contents stored on different servers, but the user must repeatedly specify classification categories and properties, increasing operation complexity
Solution Approach 1:
The replay device performs preliminary action by storing search information (classification categories and properties) in advance before the user needs to search on a new server. When switching between server devices, the previously stored search information is automatically applied to the new server, eliminating the need for users to repeatedly specify the same search parameters and significantly reducing operation complexity.
2Ease of operation
If the replay device stores and reuses search information across server switches, then the ease of operation improves, but the device complexity increases due to additional storage and management functions
Solution Approach 1:
The replay device applies universality by designing a search information storage unit that serves multiple purposes: it stores classification categories and properties for current searches, preserves them for future use when switching servers, and automatically applies them to new servers. This multi-functional design consolidates what would otherwise require separate mechanisms into a single unified system, managing complexity while enabling cross-server search continuity.

AI summary
From when any one of several DMSs 2 is selected, until contents are downloaded from that DMS 2, a DMP 1 stores the search information which has been specified for that DMS 2. And if some other DMS 2 is selected before contents have been downloaded from the DMS 2 which was first selected, then the DMP 1 specifies this search information which is stored to that other DMS 2. Accordingly, it is possible greatly to enhance the ease of use when it is not known upon which DMS 2 the desired contents is stored.
