Online Video Subtitle Synthesis for Information Completeness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users may miss important information while playing videos without subtitles, especially in noisy environments or when dialogue is in a dialect or foreign language, leading to a poor user experience.
Innovation Solution
A video processing method that parses online video files to obtain audio and video streams, generates subtitles based on the audio stream using statistical models, and synthesizes these with the video stream for display on the screen, enhancing user experience by providing subtitles and optimizing video quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If subtitles are generated and synthesized with video stream, then information completeness is improved, but processing complexity increases
Solution Approach 1:
The patent generates subtitles in advance from the audio stream before final video rendering, and pre-synthesizes them with the video stream. This preliminary action ensures that subtitles are ready when needed, improving information completeness without adding complexity during real-time playback.
Solution Approach 2:
The patent introduces an intermediate subtitle stream as a separate data layer between the audio stream and the final video output. This intermediary approach allows subtitles to be processed and synthesized independently, managing complexity by separating the subtitle generation process from the main video rendering pipeline.
2Manufacturing precision
If video processing operations are performed, then video quality is improved, but processing time increases
Solution Approach 1:
The patent performs video processing operations including decoding, rendering, and subtitle synthesis in advance before the final display. By completing these operations preliminarily, the system ensures high video quality is achieved without delaying the actual video playback to end users.
