Intelligent Video Navigation via Context Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital video navigation methods, such as scrubbers and skip buttons, often fail to accurately reflect the user's intended navigation point, leading to inefficiencies in replaying or fast-forwarding through digital videos.
Innovation Solution
Implementing intelligent navigation techniques that use context-based analysis, including scene or shot segmentation metadata, closed captioning, and aggregated user data to dynamically determine the playback point, and enhance video playback with features like slow motion, closed captioning, and extrinsic data presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional navigation methods (scrubber or skip buttons) are used, then navigation operation is simple, but navigation accuracy does not reflect user's intended point
Solution Approach 1:
The system performs preliminary analysis of video content to identify scene boundaries, shot changes, and semantic segments before navigation is needed. This pre-processing creates a structured understanding of the video that enables accurate navigation without adding complexity during the actual navigation operation.
Solution Approach 2:
The patent introduces an intermediary layer between the user's navigation request and the video playback. This intermediary analyzes the context (scene metadata, closed captions, user behavior patterns) to determine the most likely intended navigation point, thereby improving accuracy without requiring direct user specification.
2Measurement precision
If context-based analysis is performed to determine playback point, then navigation accuracy improves, but processing time increases
Solution Approach 1:
Context analysis including scene segmentation, shot boundary detection, and closed caption processing is performed in advance during video ingestion or playback initialization. This pre-computation stores structured metadata that enables rapid navigation decisions without real-time processing delays.
Solution Approach 2:
The system performs analysis only on the necessary portion of video context relevant to the navigation request, rather than analyzing the entire video. For example, when a skip button is pressed, only the preceding scene segments are analyzed to determine the optimal playback point, reducing processing overhead.
3Ease of operation
If video is enhanced with slow motion and additional data during replay, then user experience improves, but system complexity increases
Solution Approach 1:
The playback system is designed to handle multiple enhancement functions (slow motion, closed captioning, extrinsic data presentation, zooming) through a unified architecture. A single enhancement module can apply different types of enhancements based on the video segment type and user preferences, rather than requiring separate systems for each enhancement type.
Solution Approach 2:
The video enhancement features are applied dynamically based on the analyzed context of the replayed segment. For example, slow motion is automatically applied to action sequences, closed captions are enhanced for dialogue-heavy segments, and extrinsic data is presented based on scene type, allowing the system to adaptively provide relevant enhancements without overwhelming complexity.

AI summary
Automatic replay or skip ahead functionality can be configured to intelligently navigate to a portion of a video a user desires to view. The context at which a user selects intelligent navigation can be analyzed to determine where to initiate automatic replay or skip ahead. The context for intelligent navigation can be based on scene or shot segmentation data, closed captioning, aggregate video navigation data from a community of users of shared demographic traits and/or interest, and/or other metadata. In the case of automatic replay, playback of a portion of a video can include enhancements for that portion, such as providing closed captioning, display at a decreased frame rate (“slow motion”), zooming in/out on a portion of the frames of a video segment, among other enhancements.
