Video Subtitle Activation via ML Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for controlling video subtitle activation and deactivation are cumbersome, disrupting the user experience as viewers must navigate menus and select options, which can be distracting and inconvenient, especially when watching videos in different languages where audio dubbing may not match lip movements.
Innovation Solution
A streaming video application allows for automatic subtitle activation and deactivation using a machine learning model that predicts user preferences based on subtitle text, speech, background noise, and visual cues, enabling activation/deactivation by hovering over a subtitle icon or using a hot key, and allows users to enable/disable this feature in settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual subtitle activation and deactivation through menu navigation is implemented, then users can control subtitles, but user experience is disrupted and operation becomes cumbersome
Solution Approach 1:
The system performs preliminary analysis of video content characteristics (language, audio quality, visual complexity) before playback to pre-determine optimal subtitle activation points, eliminating the need for manual menu navigation during viewing
Solution Approach 2:
The subtitle system automatically activates and deactivates subtitles based on real-time analysis of video content and user preferences, making the system self-regulating without requiring user intervention through menus
2Extent of automation
If automatic subtitle activation based on content analysis is implemented, then user experience is enhanced and operation is simplified, but system complexity increases
Solution Approach 1:
The complex automation task is divided into separate modules: video content analysis module, audio quality assessment module, visual complexity evaluation module, and subtitle activation control module, each handling a specific aspect of the decision-making process
Solution Approach 2:
An intermediary processing layer analyzes video content characteristics and translates them into automated subtitle activation decisions, mediating between raw content data and user interface control without requiring direct user-system interaction

AI summary
Devices, systems, and methods are provided for presenting on-screen text during video playback. A method may include detecting a user request to determine when to activate and deactivate presentation of on-screen text during playback of a video; inputting, to a machine learning model, text data of video titles, audio data of the video titles, video frames of the video titles, and user data associated with users of a streaming video application; generating, using the machine learning model, based on the text data, the audio data, the video frames, and the user data, the first times and the second times; sending a bitstream comprising streaming video and indications of the first times and the second times; activating, based on the first times, presentation of the on-screen text during presentation of the streaming video; and deactivating, based on the second times, presentation of the on-screen text during presentation of the streaming video.
