Optical Storage Format Conversion with Chapter Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for recording disc data lack the ability to add control information such as chapters, making it inconvenient for users to manage and monitor the burning process, especially when transitioning between VCD and DVD formats, which also limits user benefits like jumping between chapters during video playback.
Innovation Solution
A method and system for format converting and recording optical storage media by loading and mapping files from one optical storage medium to another with different data compression formats, generating navigation tables, and creating a manager information file to record audio and video data, enabling format conversion and recording between VCD and DVD.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If disc data is sequentially played to a display or storage device and then burned, then the recording process is simple, but control information of chapters cannot be added
Solution Approach 1:
The patent applies preliminary action by generating navigation tables and chapter control information before the actual burning process. The system analyzes the source disc content, creates chapter markers and navigation structures in advance, and prepares all control information prior to recording, enabling chapter functionality to be embedded during the burning process without complicating the overall workflow
Solution Approach 2:
The patent introduces navigation tables as an intermediary data structure that bridges the gap between simple sequential playback and chapter-controlled playback. These navigation tables contain chapter markers, time codes, and playback control information that mediate between the raw video data and the final burned disc, enabling chapter functionality without requiring complex real-time processing during burning
2Productivity
If conventional recording method is used, then continuous suspend action is required for chapter division, but this is inconvenient for users
Solution Approach 1:
The system performs preliminary analysis of the source disc to automatically identify chapter points based on metadata, time codes, or content structure. This preliminary action eliminates the need for users to manually interrupt the recording process multiple times to insert chapter markers, thereby maintaining high recording efficiency while significantly improving user convenience
Solution Approach 2:
The patent implements self-service by enabling the recording system to automatically generate chapter structures without continuous user intervention. The system uses embedded metadata, time code analysis, and content recognition to autonomously create chapter markers, allowing the recording process to proceed continuously while still delivering chapter-divided output that meets user needs
3Adaptability or versatility
If format conversion between VCD and DVD is performed, then data compatibility is improved, but the operation process becomes complex
Solution Approach 1:
The patent applies universality by designing a format conversion system that handles multiple disc formats (VCD, DVD, DVD-RW, DVD+RW) through a unified architecture. The same navigation table generation and chapter creation mechanisms work across different formats, eliminating the need for separate complex workflows for each format conversion and simplifying the overall operation process
Solution Approach 2:
The system manages format conversion complexity by focusing on key parameter changes rather than entire structure redesign. When converting between VCD and DVD formats, the system adjusts critical parameters such as navigation table structure, chapter marker format, and time code representation, while maintaining consistent core processing logic, thereby reducing operational complexity despite format differences
Data Source
AI summary
A format converting and recording method and system for optical storage media including the steps of converting several first optical storage medium information files into the second optical storage medium through generating corresponding navigation tables which gather at a management file, transmitting image of the first optical storage medium to the second optical storage medium, and then generating a destination disc according to the management file. Thus, the operation process is simplified and the problem of lacking in playback control is solved.
