Recording Apparatus Category Identification Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in easily determining the category or identification information of additional information files associated with captured moving image files, which hinders content editing and management, especially when using external editing devices.
Innovation Solution
A recording apparatus and method that records moving image files with additional information files, including category identification information, on a recording medium, allowing external devices to communicate and display this information for easier management and editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If additional information files are recorded with moving image files, then information completeness is improved, but ease of determining file category from external devices deteriorates
Solution Approach 1:
The patent extracts the category identification information from the additional information file and stores it separately in the management information file. This allows external devices to access category information without analyzing the entire additional information file, resolving the contradiction between information completeness and ease of operation.
Solution Approach 2:
The management information file acts as an intermediary between the moving image file and external devices. It stores category identification information that mediates the interaction, allowing external devices to easily determine file categories without directly accessing or analyzing the additional information file.
2Loss of information
If additional information files are stored with moving image files, then data completeness is improved, but device complexity for external analysis increases
Solution Approach 1:
The patent extracts essential category identification information from the additional information file and stores it in the management information file. This extraction reduces the complexity for external devices to analyze only the management information file rather than the entire additional information file, while maintaining data completeness.
Solution Approach 2:
The patent segments the information storage into two parts: the moving image file and the additional information file, with category identification information stored in the management information file. This segmentation allows external devices to access only the necessary information without analyzing the entire file structure, reducing device complexity.
3Ease of operation
If category identification information is stored in management information file, then ease of access from external devices is improved, but storage structure complexity increases
Solution Approach 1:
The management information file serves multiple functions: it stores metadata about the moving image file, category identification information, and other control data. This multi-functionality allows external devices to easily access category information without requiring separate storage structures, balancing ease of access with storage structure complexity.
Data Source
AI summary
A recording apparatus to record, to a recording medium, a moving image file including video data and an additional information file, which is a file of additional information of the video data; and a control unit configured to perform control to record identification information for identifying category information of the additional information file or a data structure of the additional information file on the recording medium as a file other than the additional information file.
