Video Cover Thumbnail Grid for Scene Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video playback methods on terminal devices do not effectively allow users to quickly locate points of interest in videos, as they lack comprehensive content information, making it difficult for users to navigate and access specific scenes within a video.
Innovation Solution
A control method and apparatus that acquires a playback instruction for a video, including identification information of multiple thumbnails in the video cover, each corresponding to a scene, allowing users to determine and play the video from a specific scene based on the thumbnail identification, thereby providing a richer and more flexible playback experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single cover image is used for video files, then the device complexity is low, but the user cannot quickly locate points of interest in the video
Solution Approach 1:
The patent divides the video content into multiple scenes and creates separate thumbnail images for each scene. The cover structure is segmented to include multiple thumbnails arranged in a grid layout, allowing users to quickly locate specific points of interest by selecting the corresponding thumbnail rather than scrolling through the entire video.
Solution Approach 2:
The patent transitions from a single two-dimensional cover image to a multi-dimensional cover structure that includes multiple thumbnails representing different time points and scenes. This dimensional expansion allows users to navigate video content more efficiently by selecting from multiple scene representations simultaneously displayed on the cover.
2Loss of information
If multiple thumbnails are added to the video cover, then users can understand video content more comprehensively, but the cover structure becomes more complex
Solution Approach 1:
The video content is segmented into multiple scenes, with each scene represented by a separate thumbnail on the cover. This segmentation allows comprehensive display of video content information while maintaining organizational structure through the grid arrangement of thumbnails.
Solution Approach 2:
The patent creates thumbnail copies of key frames from different video scenes and displays them on the cover. These thumbnail copies provide visual representations of video content without requiring users to view the actual video, thus preserving information while simplifying the interface compared to displaying full video previews.
3Ease of operation
If thumbnails correspond to specific scenes, then users can navigate to specific positions in the video, but the system requires more processing to identify and mark scenes
Solution Approach 1:
The system performs preliminary scene identification and thumbnail generation during video processing, before user interaction. Scenes are automatically detected and marked with time position information in advance, so that when users click on thumbnails, the navigation function is immediately available without requiring complex real-time processing.
Solution Approach 2:
The video playback system uses the embedded time position information in thumbnails to automatically navigate to the correct scene when a user selects a thumbnail. The system self-services the navigation function by using the pre-marked time positions, eliminating the need for complex manual scene detection during playback.

AI summary
Embodiments of the present disclosure provides a control method. The method includes acquiring a playback instruction for a first video, the playback instruction including first identification information of a first thumbnail in a cover of the first video, the cover of the first video including a plurality of thumbnails, and each thumbnail corresponding to one of a plurality of scenes included in the first video; determining a first scene corresponding to the first thumbnail; and playing the first video from a position corresponding to the first scene.
