Video Node Control Interface for Chapter Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video playback technologies fail to effectively display and control video nodes, making it difficult for users to understand and interact with video content, especially in process introduction or product instruction videos, as they cannot show all nodes in one video and provide poor user experience.
Innovation Solution
A video playing control method and system that defines display nodes based on event nodes, such as timeline or spatial location nodes, allowing for a node control interface to display and manage video playback, enabling users to jump to specific nodes and update playback status, thereby improving user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple chapters correspond to multiple videos for distribution and control, then video node control is achieved, but user experience for understanding nodes and performing interactive progress control deteriorates
Solution Approach 1:
The patent merges multiple video chapters into a single video while maintaining node control capabilities. The system divides one video into multiple chapters, each representing a node, allowing users to control and navigate within a single video file rather than managing multiple separate videos. This resolves the contradiction by combining the benefits of node control with improved user experience in understanding video structure.
Solution Approach 2:
The patent segments a single video into multiple chapters or nodes, creating a hierarchical structure where one video contains multiple controllable sections. This segmentation allows users to jump between specific nodes within the video while maintaining a unified view of the entire content, improving both control capability and comprehension of node distribution.
2Ease of operation
If a video cannot display all nodes based on video display content, then video playback is simple, but user experience for understanding and interacting with video nodes deteriorates
Solution Approach 1:
The patent introduces a temporal dimension through chapter markers and progress indicators within the video interface. By adding this dimensional layer to the display, the system enables users to navigate and understand node distribution without complicating the fundamental video playback structure. Users can see chapter positions and jump between nodes while the video maintains its standard playback interface.
3Loss of information
If thumbnail display function through points on progress bar is used, then chapter location is accessible, but all nodes cannot be displayed and user understanding of node distribution deteriorates
Solution Approach 1:
The patent introduces chapter markers as intermediary elements between the progress bar and video content. These markers serve as visual indicators that represent specific nodes or chapters within the video timeline. Users can see all node positions through these markers, click to jump to specific chapters, and understand the overall node distribution without needing to manually search through the entire video.

AI summary
Content of a video is parsed to identify one or more topics of the content. The video is divided into one or more video clips corresponding to a video playback of one or more topics. One or more titles corresponding to, and descriptive of, the one or more video clips are displayed. One or more visual effects corresponding to the one or more titles and indicative of corresponding playback statuses of the one or more video clip are displayed. A video clip is played, where the video clip is based on a particular title of the one or more titles selected from a time point determined based on a corresponding playback status of the video clip.
