Separate Editable Subtitle Files for Synchronized Multimedia Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods embed subtitles within multimedia content files, making it cumbersome to change subtitle properties without reprinting the entire file, which is impractical for rapid design adjustments.
Innovation Solution
Separate subtitles from multimedia content files and store them in a separate editable file, allowing dynamic synchronization and property changes during playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If subtitles are embedded in the multimedia content file, then the subtitles are permanently fixed and cannot be changed, but this makes it cumbersome to change subtitle properties without reprinting the entire file
Solution Approach 1:
The patent divides the multimedia content into separate components: the main content file and a separate subtitle file. This segmentation allows the subtitle file to be independently edited and modified without affecting or requiring reprinting of the main multimedia content file, thus resolving the contradiction between ease of subtitle property change and file structure complexity.
Solution Approach 2:
The patent extracts the subtitle data from the multimedia content file and places it in a separate subtitle file. This extraction enables independent manipulation of subtitle properties (such as font, size, color, position) without needing to access or reprint the entire multimedia content file, thereby improving ease of manufacture for subtitle modifications.
2Adaptability or versatility
If subtitles are separated into a separate editable file, then subtitle properties can be dynamically changed, but this requires synchronization mechanisms between the multimedia content and subtitle files
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously monitors the playback position of the multimedia content file and automatically adjusts the subtitle display timing accordingly. This feedback loop ensures that subtitles remain synchronized with the content despite being stored in a separate file, resolving the contradiction between adaptability and synchronization complexity.
Solution Approach 2:
The patent introduces a subtitle synchronization mechanism that acts as an intermediary between the multimedia content file and the separate subtitle file. This mediator handles the coordination and timing alignment, allowing dynamic subtitle property changes while managing the synchronization complexity in a centralized manner.
3Productivity
If subtitles are imprinted in the multimedia content file, then the subtitles are permanently fixed, but this is not useful in a design phase where rapid change in subtitle properties is needed
Solution Approach 1:
By segmenting the subtitle data into a separate file, the patent enables rapid editing and iteration of subtitle properties during the design phase. Designers can modify subtitle content, font, size, color, and other properties without accessing or reprinting the entire multimedia content file, thus dramatically improving both productivity and ease of manufacture.
Solution Approach 2:
The patent allows subtitle files to be prepared and edited in advance during the design phase with full flexibility. All subtitle property adjustments can be made preliminarily before final deployment, enabling rapid design iterations and optimizations without the constraints of permanent embedding.
4Area of stationary object
If subtitles are placed in a small display area, then the multimedia content fits the screen, but there is not enough room for subtitles to be present in a sufficient size
Solution Approach 1:
The patent utilizes the temporal dimension to resolve the spatial conflict. Subtitles are displayed sequentially at different time points corresponding to the speech or narration in the multimedia content. This temporal separation allows the subtitle display area to be reused multiple times throughout the content, effectively providing sufficient space for readable subtitles even in small display areas.
Data Source
AI summary
The subject matter discloses a computer-implemented method, comprising: converting a subtitle file into a data structure file, the subtitle file being associated with a multimedia content file; receiving a request for playing multimedia content; as a result of said request converting the data structure file into an HTML code; and synchronizing a playing of the multimedia content file with an activating of said HTML code.
