Subtitle-Based Video Playback Advancement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face frustration when trying to skip over non-dialogue portions of videos on mobile devices, as current methods require manual intervention and often result in skipping too far or not far enough, wasting time and effort.
Innovation Solution
A playback control system that allows users to advance through videos based on subtitles by performing gestures such as tapping or shaking the device, automatically advancing playback to the next subtitle segment or break point based on a threshold difference in play positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually navigate through videos to skip non-dialogue portions, then they can control playback position, but it wastes time and effort due to skipping too far or not far enough
Solution Approach 1:
The system pre-processes video content to identify dialogue and non-dialogue segments, storing this information in advance. When a user taps to advance, the system uses this pre-analyzed structure to automatically determine the optimal skip position based on subtitle segments, eliminating the need for users to manually search through non-dialogue portions.
Solution Approach 2:
The video player automatically detects user intent through simple tap gestures and autonomously advances playback to the next relevant subtitle segment without requiring manual intervention. The system serves itself by using its own subtitle data to determine skip positions, eliminating the time-wasting manual navigation process.
2Speed
If users use existing skip functions to advance video, then playback can be fast-forwarded, but it results in skipping too far ahead and missing context
Solution Approach 1:
The system continuously monitors subtitle segment data and uses it as feedback to determine optimal skip positions. When a user taps to advance, the system references the subtitle timeline to identify the next dialogue segment, ensuring that playback advances at the precise moment when context is still relevant but non-dialogue portions can be safely skipped.
Solution Approach 2:
The skip distance is dynamically adjusted based on the actual structure of the video content rather than using fixed intervals. The system analyzes the distance between current and next subtitle segments in real-time, making the advancement speed adaptive to the specific video being watched, thus preventing both overskipping and insufficient skipping.
3Measurement precision
If users manually drag position indicator to desired play position, then they can reach specific video points, but it requires complexity of multiple interfaces and operations
Solution Approach 1:
The system extracts the essential function of position selection from the complex manual navigation process. Instead of requiring users to interact with transport bars, sliders, and multiple interface elements, the system extracts only the necessary action (tap gesture) and uses automated subtitle-based logic to determine the target position, dramatically simplifying the interface while maintaining precision.

AI summary
Systems and methods are provided for advancing through video content. The systems and methods include generating playback of a video associated with subtitles comprising a sequence of subtitle segments; receiving a user request to advance playback of the video from a first video play position corresponding to a first subtitle segment of the sequence of subtitle segments; identifying a second subtitle segment of the sequence of subtitle segments that is adjacent to the first subtitle segment in the sequence of subtitle segments; and in response to receiving the user request to advance playback of the video, advancing playback of the video from the first video play position to a second video play position based on a subtitle segment play position associated with the second subtitle segment.
