Container File Structure for Cross-File System Content Reproduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical discs and other information storage media with slow loading speeds or accessibility issues, such as contamination or physical damage, face challenges in reproducing multimedia content across different file systems, leading to inconsistent functionality and playback problems.
Innovation Solution
A container file structure is introduced, comprising a data box with component files and a meta box containing location and characteristic information, allowing for efficient reconfiguration and reproduction of content by arranging files with similar characteristics sequentially and using access patterns like random, multiple, or preloading access, and managing extents with dependency and redundancy characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If content is copied or moved to a medium using a different type of file system, then storage flexibility is improved, but content reproduction functionality deteriorates
Solution Approach 1:
The container file structure serves multiple functions: it stores component files, maintains directory structure information, and provides metadata for content reproduction. This universal structure enables the same file format to work across different file systems while preserving content reproduction functionality.
Solution Approach 2:
The patent creates a container file that copies and encapsulates the directory structure and component files from the original medium. This copied structure is then stored in a universal format that can be accessed across different file systems, maintaining functionality while improving adaptability.
2Productivity
If component files are arranged according to access patterns in the container file, then content reproduction efficiency is improved, but file system complexity increases
Solution Approach 1:
Component files are arranged in the container file according to their access patterns before reproduction occurs. Files that are accessed frequently or in sequence are positioned to optimize read operations, reducing access time and improving reproduction efficiency without requiring complex runtime file system operations.
3Quantity of substance
If content is delivered from optical discs or slow-loading media, then storage capacity is improved, but loading speed deteriorates
Solution Approach 1:
The container file structure enables preliminary organization of component files according to their access patterns. This pre-arrangement allows the reproduction apparatus to efficiently load and process content components in the optimal sequence, compensating for the slow loading speed of optical discs by minimizing access time once data is loaded.
