Video Player Assisted Seek with Pre-loaded Thumbnails
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing web-based video display systems lack effective navigation methods, particularly when fast-forwarding or rewinding through video content, as users often navigate blindly without clear visual cues beyond the locally buffered portion.
Innovation Solution
The system provides a user interface that includes thumbnails associated with time points before and after the current video playback, allowing users to interact with the interface by making gestures to control the video playback speed and direction, even when fast-forwarding past the buffered portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the video starts playing after a pre-determined amount has been received and buffered locally, then the video playback can begin quickly without waiting for the entire video to download, but the user cannot navigate to portions of the video beyond the buffered content with visual guidance
Solution Approach 1:
The system pre-loads thumbnail images for the entire video duration from the server and stores them in local memory before playback begins. This preliminary action ensures that visual guideposts are available immediately when the user needs them for navigation, resolving the contradiction between quick playback start and availability of navigation information.
Solution Approach 2:
Instead of requiring users to watch the actual video content to understand what they are skipping, the system creates and displays thumbnail copies of video frames at various time points. These thumbnails serve as visual proxies that provide navigation guidance without requiring the user to view the full-resolution video content, enabling informed fast-forwarding decisions.
2Device complexity
If small icons are used in the user interface for navigation controls, then the interface can be compact and clean, but the icons become difficult to click accurately especially when users are farther from the display device
Solution Approach 1:
The system transforms the navigation interaction from a one-dimensional small icon click to a two-dimensional gesture-based interaction. By allowing users to perform gestures (such as swiping or clicking) directly on the video display area, the interface leverages the large video canvas as the control mechanism, making navigation intuitive and accurate regardless of viewing distance while maintaining interface cleanliness.
3Manufacturing precision
If the video resolution is improved to provide better picture quality, then the visual content quality increases, but the navigation icons become even smaller and more difficult to click accurately
Solution Approach 1:
The patent eliminates the need for separate small navigation icons by integrating navigation controls directly into the video display dimension. Users can interact with the video content area itself through gestures or clicks, making the navigation capability scale with video resolution rather than being constrained by fixed icon sizes. This resolves the conflict between high video quality and ease of navigation.
Solution Approach 2:
The video display area serves multiple functions simultaneously: it displays the high-resolution video content and also acts as the navigation control interface. This multi-functionality eliminates the need for separate navigation icons, allowing the system to maintain both high picture quality and ease of operation through a unified interaction paradigm.

AI summary
A method for presenting content comprises receiving a content item; receiving a plurality of thumbnails from the content item, each thumbnail associated with a point in the content item; playing the content item starting at a first point; receiving in a user interface a selection at a second point in the content item; presenting, in the user interface, first content of the content item at the second point; and presenting, in the user interface, a subset of the plurality of thumbnails, the subset arranged based on a predetermined order and including a thumbnail associated with the second point.
