Content Transfer Metadata Tagging for Selective External Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of portable phones with limited screen size face challenges in selectively sharing content, such as photos, with external devices like TVs, as existing methods do not allow for controlled transfer of specific content, potentially revealing all stored images.
Innovation Solution
A content providing method that allows users to mark specific content as transferable to an external apparatus using meta data, enabling controlled transfer based on user-defined conditions, such as the 'open tag' feature, which ensures only tagged content is shared.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all content is transferred to external apparatus, then the user can view all stored pictures on large screen, but the user's privacy is compromised by revealing all pictures
Solution Approach 1:
The patent segments content into transferable and non-transferable portions by introducing metadata tags that mark specific content for external transfer. This allows selective sharing of only marked content while keeping other content private, resolving the contradiction between sharing convenience and privacy protection.
Solution Approach 2:
The patent applies preliminary action by pre-marking content with metadata tags before transfer. Users can designate which content should be transferable in advance, so that when external apparatus requests content, only the pre-marked content is transferred, preventing unintended privacy exposure.
2Object-affected harmful factors
If selective content transfer is implemented using metadata, then privacy is protected by transferring only marked content, but the system complexity increases due to metadata processing
Solution Approach 1:
The patent uses universal metadata tags that can be applied to various types of content (pictures, videos, etc.) and work across different external apparatus. This multi-functional approach simplifies the overall system by using a single metadata mechanism for all content types, reducing complexity despite the selective transfer capability.
Data Source
AI summary
A content providing method of an electronic apparatus communicably connected with an external apparatus is provided. The method includes receiving a command for transferring content to the external apparatus; checking whether the content includes information indicating that the content is transferable to the external apparatus, the information being set by determining, based on a meta data included in the content, whether a predetermined condition is satisfied; and transferring the content, based on the checked information, to the external apparatus.
