Conversion Management Information for Multimedia File Hierarchy Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for format conversion of multimedia content lack effective management of conversion history, leading to cumbersome manual checks and increased errors in retrieving source files, resulting in frequent re-transcoding and difficulties in recovering original files.
Innovation Solution
An information processing device and method that acquire and manage file information to generate conversion management information, including clip information and family-tree information, to track the hierarchy of format conversions, allowing easy retrieval and recovery of source files.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual checking of each file is performed to retrieve conversion-source parent file, then retrieval accuracy can be maintained, but operation time and labor increase significantly
Solution Approach 1:
The patent creates a virtual copy of the file hierarchy structure through the family-tree information representation. Instead of manually checking physical files, the system copies the hierarchical relationships into a data structure that can be traversed electronically, enabling fast retrieval while maintaining accuracy.
Solution Approach 2:
The patent replaces the mechanical manual file-checking process with an automated information processing system. The family-tree information structure substitutes for physical file browsing, and the processing device automatically traverses the hierarchy to retrieve conversion-source parent files, eliminating manual labor while maintaining precision.
2Adaptability or versatility
If format conversion is performed multiple times to handle diverse content standards, then adaptability improves, but system complexity increases
Solution Approach 1:
The patent segments the complex conversion hierarchy into manageable units by representing each conversion level as a separate node in the family-tree information structure. This segmentation allows the system to handle diverse format conversion requirements while maintaining clear, organized representation of the conversion relationships.
Solution Approach 2:
The patent adds an informational dimension by creating family-tree information that represents the hierarchical structure of conversions. This additional dimension of organization allows multiple conversion operations to be managed systematically, transforming the complexity from an unorganized mess into a structured data representation that is easier to process.
3Measurement precision
If extensive format conversion history is maintained, then retrieval accuracy improves, but information management complexity increases
Solution Approach 1:
The patent extracts only the essential information needed for accurate retrieval from the complete conversion history. By representing the hierarchy as family-tree information with key attributes (conversion-source parent file, converted file, conversion parameters), the system maintains sufficient accuracy while reducing the complexity of managing the full history.
Solution Approach 2:
The patent creates a universal family-tree information structure that serves multiple functions: tracking conversion sources, managing conversion parameters, and enabling retrieval operations. This multi-functional representation reduces the need for separate management systems, thereby reducing overall complexity while maintaining comprehensive information.
Data Source
AI summary
An information processing device includes a file-information acquirer and a conversion-management information generator. The file-information acquirer is configured to acquire file information that is information regarding a file to be subjected to conversion processing for converting a clip format. The conversion-management-information generator generates conversion management information that manages an identity of a clip created by the conversion processing performed on a clip to which the file corresponding to the file information belongs, by using the file information acquired by the file-information acquirer.
