Automated DVD Transition Video Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing DVD authoring applications require repetitive editing steps to create transition videos between different DVD items, making it cumbersome to adjust for changes in menu layout or playback order, as the original transition video becomes unsuitable.
Innovation Solution
A media content generation method and system that automatically generates a new playable item to simulate a transition effect between two existing items, using an authoring tool and effect generator to retrieve adjacent playlist items and create a seamless transition effect, which can be adjusted and rendered for various playback formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a transition video is created based on specific DVD items and playback order, then the transition effect is customized for that specific sequence, but any change in menu layout or playback order makes the original transition video unsuitable, requiring repetitive editing steps
Solution Approach 1:
The system automatically generates transition videos by retrieving adjacent playlist items and applying transition effects without requiring manual re-editing. When menu layout or playback order changes, the system self-adjusts by automatically identifying the new adjacent items and regenerating the transition video, eliminating the need for repetitive manual editing steps.
Solution Approach 2:
The system pre-establishes a library of transition effects and prepares the infrastructure to automatically retrieve and apply appropriate transitions. When changes occur in menu layout or playback order, the system can immediately generate new transition videos using pre-prepared transition templates, avoiding the need for time-consuming manual creation of each transition.
2Productivity
If manual editing steps are used to create transition videos, then each transition can be precisely controlled, but the process becomes troublesome and time-consuming when adjustments are needed
Solution Approach 1:
The patent replaces manual mechanical editing operations with an automated computer-based system. The authoring tool automatically retrieves playlist information, identifies adjacent items, selects appropriate transition effects, and generates transition videos without human intervention in the actual creation process, thereby reducing time consumption and simplifying the overall process.
Solution Approach 2:
The system creates a universal transition video generation mechanism that can handle various types of DVD items (menus, titles, chapters) and different transition effects through a single integrated process. The authoring tool serves multiple functions: retrieving playlists, identifying adjacent items, selecting transitions, and generating videos, eliminating the need for separate manual editing operations for each function.

AI summary
A playable volume generation method is provided. A playlist includes a plurality of playlist items, each targeting one of the playable items to be displayed according to the arrangement of the playlist items. A designated inter-item position on the playlist for inserting a new playlist item is received. A former playlist item and a later playlist item adjacent to the new playlist item are automatically retrieved. A second playable item targeted by the new playlist item is automatically generated to simulate a transition effect transitioning from the end of the playable item targeted by the former playlist item to the beginning of the playable item targeted by the later playlist item.
