Video Segment Navigation via Thumbnail Timeline Scrubbing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in intuitively and efficiently browsing and viewing multiple videos on electronic devices, as existing systems lack effective methods for navigating and rendering specific video segments without cumbersome browsing through entire videos.
Innovation Solution
An electronic apparatus determines an ordered set of separate videos, identifies a video segment within each video, and displays representative images along an axis, allowing users to scrub through these representations to select and render specific frames or segments efficiently, with the ability to switch between videos without intervening content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If users browse through entire videos to find specific segments, then they can view complete video content, but the browsing time and operational complexity increase significantly
Solution Approach 1:
The video is divided into multiple video clips, each represented by a thumbnail image in the storyboard. Users can directly select specific clips of interest rather than browsing through the entire video sequentially. This segmentation allows users to quickly identify and navigate to desired content segments, dramatically reducing browsing time while maintaining ease of operation through visual preview thumbnails.
2Productivity
If multiple videos are displayed together with their representations, then users can navigate between videos efficiently, but the device complexity and interface complexity increase
Solution Approach 1:
The patent displays multiple video representations (thumbnails) along a horizontal axis, creating a visual timeline dimension. This spatial arrangement allows users to perceive video duration, sequence, and content at a glance. The horizontal positioning of thumbnails provides an intuitive visual map of video content without requiring complex controls or interfaces, thereby improving navigation efficiency while keeping the interface simple.
3Loss of information
If the entire video is rendered for viewing, then users can see complete content, but the time required to view and locate specific segments increases
Solution Approach 1:
Thumbnail images are generated and displayed in advance for each video clip before the user watches the actual video content. These preliminary visual representations allow users to preview and identify interesting segments without having to watch through entire videos. Users can make informed decisions about which segments to view based on the pre-displayed thumbnails, thereby accessing desired video content quickly while retaining full content accessibility.

AI summary
A method comprising determining an ordered set of separate videos that comprises a first video and a second video, identifying a first video segment comprised by the first video, determining an ordered set representation that indicates the ordered set of separate videos, the ordered set representation comprising a first representative image that represents the first video and a second representative image that represents the second video, causing display of the ordered set representation, receiving information indicative a scrub input, causing movement between the ordered set representation and an index point based on the scrub input, determining that the index point is aligned with the first representative image determining a rendering position based the first representative image, identifying a frame of the first video segment, and causing display of a frame image in a video rendering region is disclosed.
