Mobile Data Preview via Native-to-Preview Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data storage systems face inefficiencies in archiving and accessing large data files, particularly on mobile devices, due to resource-intensive processes and lack of optimization, which affects performance and user experience.
Innovation Solution
The system converts large data files from their native format to a preview format, reducing storage space and bandwidth requirements, allowing users to browse files efficiently without the need for full file retrieval, using stub files that minimize computational resources and enable quick content viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If large data files are stored in native format on mobile devices, then data quality and completeness are maintained, but storage space and processing resources are excessively consumed
Solution Approach 1:
The patent segments data files into two formats: full native format for complete data quality and compressed preview format for space efficiency. The system divides storage into primary storage for preview versions and archive storage for full versions, allowing mobile devices to maintain space-efficient representations while preserving access to complete data when needed.
Solution Approach 2:
The patent creates compressed preview copies of large data files that can be stored locally on mobile devices. These preview copies are sufficient for browsing and viewing purposes, eliminating the need to store and process full-resolution native files while maintaining adequate data quality for most user interactions.
2Ease of operation
If full data files are retrieved from archive storage, then complete data access is achieved, but network bandwidth and processing time are excessively consumed
Solution Approach 1:
The patent implements partial action by retrieving only the compressed preview copy from archive storage when users need to browse or view files, rather than retrieving the complete full-resolution file. This partial retrieval provides sufficient functionality for most operations while consuming minimal network bandwidth and processing resources.
Solution Approach 2:
The patent changes the resolution and compression parameters of stored data representations. Preview copies are stored at lower resolution with higher compression ratios, while full-resolution versions are maintained in archive storage. The system dynamically selects which parameter set to use based on user needs, achieving fast access for browsing while preserving complete quality when necessary.
3Productivity
If preview format conversion is implemented, then storage efficiency and browsing speed are improved, but data conversion processing time is increased
Solution Approach 1:
The patent performs preliminary action by converting large data files to compressed preview format during initial archive operations, before users need to access them. This upfront conversion ensures that when users browse or view files, the space-efficient preview versions are already available, eliminating conversion delays during user interactions and maximizing browsing efficiency.
Data Source
AI summary
Techniques for providing data preview before recalling large data files are disclosed. In one aspect, a data file is made accessible while being offline by converting the data file from a native format to a preview format, storing the data file in the preview format in a primary storage that is locally available and moving, after the conversion to the preview format, the data file in the native format to a secondary storage. When a viewing request is received for the data file, the data file in the preview format is displayed to fulfill the viewing request.
