NFC Triggering Label for DLNA Media File Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing DLNA technology for media file sharing is complex and prone to errors due to the need for multiple layers of operation and manual device selection, making it difficult to share files quickly and accurately.
Innovation Solution
A method and system that preset a local area network (LAN) and DLNA application as defaults, generate an NFC triggering label embedded with the sharing pair relationship, and activate it for automatic login and pairing between master and slave devices, enabling simple and accurate media file sharing through NFC sensing operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional DLNA technology is used for media file sharing, then media files can be shared between devices, but the operation process becomes complex and prone to errors
Solution Approach 1:
The patent applies preliminary action by pre-configuring sharing information including LAN details, DLNA application parameters, media file identifiers, and device pairing relationships into an NFC triggering label before the actual sharing operation. This pre-packaging of all necessary sharing parameters eliminates the need for complex real-time configuration during file sharing, thereby reducing operational complexity while maintaining sharing reliability
Solution Approach 2:
The patent introduces an NFC triggering label as an intermediary carrier that stores and transmits sharing information between devices. This intermediary element simplifies the direct device-to-device communication process by providing a pre-configured information package, reducing the complexity of direct DLNA pairing operations while ensuring accurate file sharing
2Productivity
If manual device selection and multiple layer browsing is required, then comprehensive device search is achieved, but user operation time increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring sharing information including LAN details, DLNA application parameters, media file identifiers, and device pairing relationships into an NFC triggering label before the actual sharing operation. This pre-packaging of all necessary sharing parameters eliminates the need for complex real-time configuration during file sharing, thereby reducing operational complexity while maintaining sharing reliability
Solution Approach 2:
The patent extracts the essential sharing parameters (LAN information, DLNA application settings, media file identifiers, and device pairing relationships) from the complex DLNA configuration process and consolidates them into a compact NFC triggering label. This extraction simplifies the user interaction to a single NFC scan operation, dramatically reducing operation time while maintaining complete device search and selection capabilities

AI summary
A media file sharing method and a media file sharing system are provided. The sharing method comprises: presetting and saving an LAN, a DLNA application and a media file that are default during a sharing process; establishing a sharing pair relationship between a master device and a slave device in the DLNA application; generating an NFC triggering label embedded in the master device according to the LAN, the DLNA application, the media file and the sharing pair relationship; activating the NFC triggering label by the master device through an NFC sensing operation; the master device and the slave device logging into the LAN and the DLNA application that are default according to the NFC triggering label and completing the sharing pairing according to the sharing pair relationship; receiving the media file from the master device by the slave device and completing processing of the media file. Thereby, the present disclosure can achieve sharing of a media file quickly through very simple operations and at a high accuracy.
