Chapter Menu with Attribute Diagrams for Video Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video reproduction devices lack sufficient information for users to navigate video content efficiently, particularly for resuming playback from a specific time or accessing a specific scene without re-watching from the beginning, as users often rely on fast-forward searching which is an unpleasant experience.
Innovation Solution
A reproduction device and method that generate and display attribute-based chapter menus, including a graphic timeline and attribute diagrams, such as violence levels and actor participation, allowing users to select chapters based on additional information, enhancing navigation and user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a traditional chapter menu with only thumbnails is used, then the device complexity is low, but the information sufficiency for user navigation is insufficient
Solution Approach 1:
The chapter menu is segmented into multiple information layers: basic thumbnail view, detailed attribute information (violence level, actor presence, location, time), and interactive timeline. This segmentation allows users to access detailed information only when needed, maintaining a simple default view while providing comprehensive information on demand.
Solution Approach 2:
The patent adds a temporal dimension to the chapter menu by introducing a timeline that visually represents the chronological structure of the video content. This timeline dimension allows users to navigate based on time references and understand the sequence of chapters, transforming the traditional static 2D thumbnail grid into a multi-dimensional navigation interface.
2Loss of time
If users navigate using fast-forward mode to find specific scenes, then the device complexity remains low, but the navigation time and user experience deteriorate
Solution Approach 1:
The system performs preliminary analysis of video content to extract and store attributes such as violence level, actors present, locations, and time references for each chapter. This preliminary processing enables users to quickly locate desired scenes through the enhanced chapter menu without manual fast-forwarding, significantly reducing navigation time.
Solution Approach 2:
The chapter menu provides immediate visual feedback about chapter content through thumbnails, attribute indicators, and timeline positioning. When users hover over or select a chapter, the system provides feedback about what content is available, allowing users to make informed decisions quickly without trial-and-error fast-forwarding.
3Ease of operation
If detailed attribute information is added to chapter menus, then the user comfort and navigation efficiency improve, but the ease of operation may deteriorate due to information overload
Solution Approach 1:
Different parts of the chapter menu provide different types of information tailored to user needs: thumbnails provide visual content previews, attribute indicators (violence level, actors) provide content warnings and identification, and the timeline provides temporal context. This local differentiation of information quality allows users to quickly scan for relevant details without being overwhelmed by all information simultaneously.
Solution Approach 2:
The chapter menu is designed as a dynamic interface that adapts to user interactions. Information is revealed progressively based on user actions such as hovering, clicking, or selecting different view modes. The timeline can be expanded or collapsed, and attribute details can be shown or hidden, allowing the interface complexity to adjust dynamically to user needs rather than presenting all information statically.

AI summary
The reproduction device is for displaying video information comprising a plurality of chapters. The reproduction device comprises a control unit which is configured to initiate a display of a chapter menu having selectable menu items. Further, the control unit is configured to initiate a reproduction of a chapter of the video information upon selection of the dedicated menu item. The reproduction device is configured to generate attributes of the chapters which are indicative to a respective one of the chapters and to generate a display diagram of the attributes. This diagram may be displayed in the chapter menu.
