Video Thumbnail Search System for Rapid Event Location
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional video management systems require manual, time-consuming scrolling through long video segments to find specific events, leading to high bandwidth usage and long load times, especially when searching large recorded video files.
Innovation Solution
A computer system for video management that enables user selection of thumbnails representing evenly distributed segments of recorded video, allowing for rapid searching and display of representative images, which progressively shorten the video duration until a minimum length is reached, at which point the full video is loaded and displayed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual scrolling through long video segments is used to search for specific events, then users can review video content, but the search process becomes time-consuming and requires tedious scrolling through long durations of video
Solution Approach 1:
The patent divides long video segments into smaller, manageable clips with generated thumbnails representing each clip. Users can visually scan thumbnails instead of scrolling through continuous video, significantly reducing search time while maintaining the ability to review content by selecting感兴趣的 thumbnails.
2Reliability
If large segments of video are loaded from storage for searching, then complete video content is available for review, but load times increase and bandwidth usage increases
Solution Approach 1:
The patent extracts only representative frames from video segments to generate thumbnails, which are then displayed for user selection. This extraction approach allows users to search and navigate video content without loading the entire video data, reducing bandwidth usage and load times while maintaining search effectiveness.
Solution Approach 2:
The system pre-generates thumbnails from video segments during ingestion or idle periods, so that when users need to search, the thumbnail images are already available for immediate display. This preliminary action eliminates the need to load and process full video frames during user search operations.
3Quantity of substance
If traditional file hierarchy storage is used for video data, then video can be stored and accessed, but searching requires loading large video segments which consumes high bandwidth
Solution Approach 1:
The patent segments video data into smaller clips and generates thumbnail representations for each segment. This segmentation allows the system to store video efficiently while enabling users to search by selecting thumbnails, dramatically reducing the bandwidth required to access and search video content compared to loading entire video segments.

AI summary
A computer system for video management may provide a GUI that may enable repeating the steps of user thumbnail selection, representative subdivision of a recorded video to be viewed based on the thumbnail selected, and display of representative thumbnails in a GUI. The representative thumbnails may be selected based on a parameter such as random selection or images that may be evenly distributed from within the recorded video. After the representative subdivision of a recorded video to be viewed reaches a lower limit, the computer system for video management may display a shortened portion of video in the GUI to be viewed.
