Context-Driven Digital Content Rewind System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for rewinding digital content, such as time-based and scene-based rewinds, do not consider verbal dialog, leading to over-rewind and disruption of the mental flow of the story.
Innovation Solution
A context-driven rewind system that dynamically and automatically rewinds digital content to the beginning of the last detected dialog segment based on verbal commands or manual triggers, utilizing facial recognition, lip movement detection, and scene change analysis to verify dialog segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If time-based rewind is used to rewind digital content, then the viewer can rewind to a fixed time point, but the viewer may rewind too far back and miss the beginning of important dialog segments
Solution Approach 1:
The patent segments the digital content into distinct dialog segments using voice activity detection. Instead of treating the content as a continuous stream, the system identifies and marks specific segments where dialog occurs, allowing precise rewind to the beginning of a dialog segment rather than a fixed time point. This segmentation enables the viewer to rewind to the exact start of missed dialog without going back further than necessary.
Solution Approach 2:
The patent replaces the mechanical time-based rewind mechanism with an intelligent system that uses voice activity detection and scene change detection. Instead of simply moving backward by a fixed time interval, the system analyzes the content to identify dialog segments and automatically calculates the optimal rewind point, substituting automated intelligent processing for manual time-based control.
2Ease of operation
If scene-based rewind is used to rewind digital content, then the viewer can rewind to scene change points, but the rewind may still not align with the beginning of dialog segments
Solution Approach 1:
The patent merges two detection mechanisms: voice activity detection for identifying dialog segments and scene change detection for identifying natural break points in the content. By combining these two detection methods, the system determines the optimal rewind point that satisfies both conditions - aligning with scene changes while also capturing the beginning of dialog segments. This merged approach provides both ease of operation and information preservation.
Solution Approach 2:
The system uses feedback from multiple detection mechanisms to continuously refine the rewind point. Voice activity detection provides feedback about dialog segments, scene change detection provides feedback about natural breaks, and the system uses this combined feedback to automatically adjust and determine the precise rewind location that maximizes both operational ease and information retention.
3Ease of operation
If manual rewind trigger is used, then the viewer has full control over rewind timing, but the viewer must manually determine the optimal rewind point
Solution Approach 1:
The patent implements a self-service rewind system that automatically performs the work of identifying dialog segments and calculating optimal rewind points. When the viewer activates rewind (through a simple trigger), the system autonomously analyzes the content, detects voice activity patterns, identifies scene changes, and determines the precise rewind location without requiring the viewer to manually search or estimate the correct timing. The system serves itself by using its own detection capabilities to make the rewind decision.
Solution Approach 2:
The system performs preliminary analysis of the digital content to pre-identify dialog segments and their boundaries before the viewer needs to rewind. By continuously monitoring voice activity and scene changes in real-time, the system is already prepared with the information needed to determine the optimal rewind point, eliminating the time the viewer would otherwise spend searching for the correct segment.

AI summary
Example embodiments provide systems and methods for rewinding digital content during playback based on context of the digital content. A content rewind system electronically accesses digital content. A rewind trigger is detected by the system. The system analyzes the digital content to detect at least one dialog segment within the digital content. The analysis is based on context of the digital content (e.g., dialog within the digital content). The system rewinds playback of the digital content by rewinding to a starting point of a previous dialog segment.
