Moving Thumbnail Generator for Video Search Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In on-demand video systems, navigating and efficiently searching through a large volume of video content is challenging due to bandwidth requirements and the need for effective navigation tools, as traditional fixed channel systems become unwieldy, and free-form textual searches often return voluminous results, making it difficult for users to quickly find relevant video segments.
Innovation Solution
A moving thumbnail generator that creates tagged and time-stamped thumbnails from video trigger events within original video files, summarizing the content and providing relational links back to the original files, allowing users to visually and aurally assess relevance and retrieve the corresponding videos.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If free-form textual search is used over a large corpus of video content, then the system can handle large volumes of video data, but it returns voluminous amounts of search results that are difficult for users to sort through efficiently
Solution Approach 1:
The patent creates moving thumbnail copies that represent video content segments. These moving thumbnails are generated from key frames extracted at video trigger events and serve as visual proxies for the actual video content, allowing users to quickly assess relevance without watching full videos or scrolling through extensive text results
Solution Approach 2:
The patent employs visual changes in the moving thumbnails including frame transitions, color animations, and visual indicators to convey information about video content. The moving thumbnails display sequences of frames that visually represent the video segment content, enabling rapid visual scanning and assessment
2Device complexity
If traditional fixed channel systems are used for video navigation, then the system structure is simple, but it becomes increasingly unwieldy to operate as the corpus of available content grows larger
Solution Approach 1:
The patent segments the large video corpus into manageable units represented by moving thumbnails. Each moving thumbnail corresponds to a specific video segment triggered by relevant events, breaking down the overwhelming content corpus into visually distinct, easily navigable units that users can quickly scan and select
Solution Approach 2:
The moving thumbnail serves as an intermediary between the user and the actual video content. It provides a visual preview that mediates the user's selection process, allowing users to assess video relevance without directly interacting with the full video content or complex navigation structures
3Productivity
If users need to quickly assess video relevance in search results, then navigation efficiency improves, but bandwidth requirements increase for distributing video content
Solution Approach 1:
The patent extracts key frames from video content at trigger events to create moving thumbnails. This extraction process removes only the essential visual information needed for assessment, significantly reducing the data bandwidth required compared to distributing or streaming full video content while maintaining user ability to assess relevance

AI summary
Various methods, apparatuses, and systems are described for a moving thumbnail generator. The moving thumbnail generator generates one or more moving thumbnails that are tagged and time-stamped to arbitrary video trigger events that take place in an associated original video file. Each of the moving thumbnails has two or more moving frames derived from its associated original video file at a portion in the original video file that is tagged and time-stamped to one or more relevant video trigger events in order for the generated moving thumbnail to summarize a visual content of the associated original piece of video file to a user. The tag carries information about content that takes place in the original video file and metadata about that content including a time reference to frames that are contextually relevant to the reason why a viewer of the thumbnail might be interested in viewing that thumbnail.
