Dynamic Tag Cloud for Video Tapestry Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video content preview mechanisms, such as thumbnail images and descriptive information, are insufficient for users to quickly find relevant video content or navigate to specific portions within a media presentation.
Innovation Solution
A video tapestry displaying blended frames from different portions of a media presentation, combined with a dynamic tag cloud generated from keywords associated with these frames, allowing improved navigation and understanding of the content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If thumbnail images and descriptive information are displayed for video content, then basic video information is provided to users, but users cannot quickly find relevant video content or navigate to specific portions within the media presentation
Solution Approach 1:
The patent segments the video content into multiple portions and creates separate tag clouds for each portion. When users interact with the video tapestry (e.g., hovering over or clicking a specific frame), the system divides the overall video information into segment-specific tag clouds, allowing users to quickly access detailed information about particular portions without browsing through the entire video content.
Solution Approach 2:
The patent adds a new dimension to video preview by incorporating dynamic tag clouds that change based on user interaction with the video tapestry. Instead of static thumbnails and descriptions, the system creates a multi-dimensional navigation experience where tag clouds are generated and displayed in response to user actions, providing both spatial (visual frames) and semantic (keyword tags) dimensions for content exploration.
2Ease of operation
If a video tapestry with blended frames from different portions is displayed, then visual summary and navigation capability are improved, but the system complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-generating tag clouds for different portions of the video content before user interaction. The video tapestry is pre-assembled with blended frames from various portions, and corresponding tag clouds are prepared in advance. When users interact with the tapestry, the system simply retrieves and displays the pre-generated tag clouds, avoiding the need for complex real-time generation during user sessions.
Solution Approach 2:
The patent introduces an intermediary layer between the video content and the user interface. The video tapestry acts as an intermediary visual representation that maps to underlying video portions, while the tag cloud generation system serves as an intermediary that translates user interactions into relevant keyword displays. This intermediary architecture simplifies the user interface while managing the complexity of content representation and interaction handling.

AI summary
A video tapestry comprising a plurality of blended frames of a media presentation can be presented, with the frames comprising two or more frames displayed simultaneously. A dynamic tag cloud can be presented based on data identifying different portions of the tapestry for use in navigation or understanding the video content. A method can comprise obtaining a plurality of keywords for content of a media presentation, associating a first keyword with a first tag cloud and associating a second keyword with a second tag cloud, and generating a program component for providing a dynamic tag cloud using the first and second tag clouds. The program component can display the first tag cloud when the first portion of the video tapestry is referenced and the second tag cloud when the second portion of the video tapestry is referenced. The portions may be referenced by user input, a play head, or other activity.
