Video Data Organization for DVD-Download Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing DVD technologies face challenges in converting dual layer content from DVD-ROMs to DVD-Download discs due to incompatibilities in layer break specifications, requiring significant time and resources for re-authoring, which limits the availability of DVDs in on-demand models.
Innovation Solution
The technology involves analyzing video data to identify potential layer breaks and calculating a buffer space to reposition data, allowing for the creation of DVD-Download disc images from DVD-ROM images, ensuring compliance with DVD-Download specifications without the need for re-authoring, by inserting a buffer space to meet the required layer break positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dual layer content is converted from DVD-ROM to DVD-Download disc format, then the availability of DVDs in on-demand models increases, but significant time and resources are required for re-authoring due to incompatibilities in layer break specifications
Solution Approach 1:
The patent applies preliminary action by pre-calculating and inserting a buffer space into the video data during the conversion process from DVD-ROM to DVD-Download disc format. This buffer space is positioned at a calculated location that anticipates and prevents layer break specification incompatibilities, eliminating the need for time-consuming re-authoring operations later. The buffer space insertion is performed in advance to ensure seamless compliance with DVD-Download specifications.
2Manufacturing precision
If re-authoring is performed to convert dual layer content between DVD-ROM and DVD-Download formats, then compliance with target format specifications is achieved, but costs and processing time increase significantly
Solution Approach 1:
The patent extracts the problematic layer break specification incompatibility by removing the conflicting data portion and replacing it with a buffer space. This buffer space acts as a separator that allows the video data to be reorganized into chunks that comply with DVD-Download specifications without requiring complete re-authoring. The extraction approach isolates and resolves the specification conflict efficiently.
Solution Approach 2:
The patent applies parameter changes by modifying the data structure parameters of the video content during conversion. Specifically, it changes the organization of video data into chunks separated by buffer spaces, and adjusts the layer break positions to match DVD-Download specifications. These parameter modifications enable format conversion while maintaining compliance and improving processing efficiency.
3Reliability
If buffer space is inserted to offset video data position and meet layer break specifications, then seamless playback is ensured, but data reorganization complexity increases
Solution Approach 1:
The patent introduces a buffer space as an intermediary element between video data chunks. This buffer space acts as a mediator that resolves the conflict between maintaining continuous seamless playback and adhering to layer break specifications. The buffer space is strategically positioned to ensure that layer breaks occur at appropriate boundaries while maintaining the illusion of continuous data flow during playback, thus ensuring reliability without requiring complex real-time processing.

AI summary
In organizing video data, an analysis can be performed to determine whether the video data meets specifications for organization on storage media. Potential breaks in the video data may be identified for organizing the video data on discrete physical portions of the storage media. A buffer space may be calculated based on an identified potential break for spacing the video data around the potential break to meet the data organization specifications.
