Portable Device RSS Feed Generation for Content Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods do not allow portable devices to efficiently communicate updated content information to other devices, such as PCs, without users manually checking each piece of content, and lack a user-friendly interface for obtaining updates on newly generated content from devices like digital cameras and camcorders.
Innovation Solution
A method and apparatus for a portable device to generate and send a rich site summary (RSS) feed containing information about renewed contents, including metadata, to an RSS reader, while ensuring only authorized devices receive this information, using a certification process to protect private content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a user manually checks each content piece on a portable device, then the user can see all updated contents, but the user experiences high time loss and operational complexity
Solution Approach 1:
The patent extracts only the essential information about updated contents (title, date, thumbnail) from the full content data and presents it through an RSS feed. This allows users to obtain update information without accessing or manually checking each complete content piece, thereby reducing time loss while maintaining information completeness.
Solution Approach 2:
The patent introduces an RSS feed as an intermediary mechanism between the portable device and the user's PC. This intermediary automatically transmits content renewal information without requiring manual checking, enabling users to receive updates passively and reducing both time loss and operational complexity.
2Loss of information
If a portable device provides detailed content information directly, then users can access comprehensive data, but the interface complexity increases and user-friendliness decreases
Solution Approach 1:
The patent extracts only the most relevant content metadata (title, creation date, thumbnail image) and presents it in a simplified RSS feed format. This selective extraction maintains essential information while presenting it in a user-friendly manner that is easy to understand and operate, avoiding the complexity of displaying all detailed content information.
Solution Approach 2:
The patent creates a simplified copy of the content information structure through the RSS feed format. Instead of presenting the original complex content data directly, it generates a streamlined representation that preserves key information while improving interface user-friendliness and ease of operation on PCs.
3Loss of information
If the portable device sends all content data to the RSS reader, then the reader has complete information, but the data transmission volume increases and security risks increase
Solution Approach 1:
The patent extracts only non-sensitive content metadata (title, date, thumbnail) for transmission through the RSS feed, while excluding detailed content data and sensitive information. This selective extraction ensures that sufficient information is transmitted for user awareness while minimizing security risks associated with transmitting large volumes of data.
Solution Approach 2:
The patent applies different quality levels to different data elements: high quality (complete details) for locally stored content on the portable device, and low quality (summary only) for transmitted RSS feed data. This local quality differentiation maintains information completeness where needed while reducing security risks in transmission.
4Extent of automation
If the portable device implements automatic RSS feed generation, then content update notification is automated, but the device complexity increases
Solution Approach 1:
The patent implements self-service automation where the portable device automatically detects content changes and generates RSS feeds without requiring manual user intervention. The system monitors itself, detects renewals, and initiates feed generation autonomously, achieving high automation while keeping the complexity manageable through standardized RSS protocols.
Data Source
AI summary
A method of allowing a portable device to provide a rich site summary (RSS) feed including information about renewal of contents, and an apparatus performing the method are provided. If contents of the portable device are renewed, the portable device generates an RSS feed for the renewed contents and sends the RSS feed to an RSS reader, and accordingly, a related art web-based RSS service is expanded to the portable device. Therefore, even if the user does not browse all contents of the portable device, a user of the portable device can easily see only information about contents that are recently updated using another device such as a personal computer (PC).
