Content Providing Device for Network Storage Backup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for providing contents via networks often result in altered data that is not easily accessible in their original form, and there is a need for efficient data backup solutions when primary storage devices are unavailable, especially considering the varying capabilities of devices such as PDAs, smartphones, and PCs.
Innovation Solution
A system and method that includes a content providing device modifying original contents to suit receiving devices, generating metadata with location information for accessing original contents, and a data backup system that transfers data to available storage devices via a network when primary devices are unavailable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If original contents are provided via network for use, then accessibility of original contents is improved, but device compatibility becomes problematic due to varying resolution and codec capabilities
Solution Approach 1:
The system segments content delivery into two parts: modified contents (transcoded and resized) are provided for immediate viewing on various devices, while location information of original contents is stored separately. This allows devices to access appropriately formatted content without requiring all devices to support all original content formats.
Solution Approach 2:
The system introduces an intermediary mechanism (content providing device) that receives original contents, modifies them according to device capabilities, and provides both the modified contents and location information. This intermediary handles the compatibility translation between different device requirements and original content formats.
2Ease of manufacture
If contents are transcoded or resized for webpage display, then ease of uploading and displaying contents is improved, but loss of original content quality and accessibility occurs
Solution Approach 1:
The system creates modified copies of original contents (transcoded and resized versions) for webpage display, while preserving the original contents stored at a known location. Users can access the high-quality original copies when needed, eliminating the loss of information while maintaining ease of display.
Solution Approach 2:
The system performs preliminary modification of contents into multiple formats and resolutions before uploading, storing both the modified versions for immediate use and the original versions for later retrieval. This preliminary action prevents quality loss during display while maintaining original quality availability.
3Reliability
If data is backed up to primary storage device, then backup reliability is improved, but system fails when primary storage device is unavailable
Solution Approach 1:
The backup system dynamically selects storage devices based on availability. When the primary storage device is unavailable, the system automatically switches to alternative storage devices connected to the network. This dynamic adaptation maintains backup reliability while accommodating changing system conditions.
Solution Approach 2:
The system prepares multiple storage devices as backup options in advance. When the primary storage device becomes unavailable, the system can immediately use pre-configured alternative storage devices, cushioning against the failure without interruption to the backup process.
4Manufacturing precision
If high quality original contents are stored, then content quality is improved, but storage capacity requirements increase for devices with limited capacity
Solution Approach 1:
The system applies local quality by providing different quality levels of content to different devices based on their capabilities. High-quality original contents are stored on network storage devices with sufficient capacity, while modified lower-quality versions are provided to devices with limited storage capacity, optimizing both quality and storage efficiency.

AI summary
Provided are methods and apparatuses for providing contents via a network, in which original data of contents provided via a network can be traced, and contents that are modified according to performance of a contents receiving device is provided. Location information of original contents is added to metadata of contents provided via the network to thereby increase convenience of access to the original contents and modify attributes of contents that are provided, to be suitable for the performance of the contents receiving device.
