Video Thumbnail Display Constraining Sensitive Content Exposure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in understanding video content without impairing the viewing or listening experience due to excessive information presentation, particularly when long video content requires significant time to fast-forward and preview thumbnails may reveal story developments or endings.
Innovation Solution
An electronic apparatus with an image extraction module that extracts representative images from video content, a display constraining function to limit the display of sensitive content, and a playback module for responsive playback, allowing users to navigate video content without spoiling key moments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a list of thumbnail images is displayed to present an outline of video content, then the user can understand the content structure, but the viewing/listening value is impaired due to excessive information presentation
Solution Approach 1:
The patent applies local quality by differentiating the display treatment of thumbnail images based on their temporal position in the video content. Thumbnails before the constraining position are displayed normally to provide information, while thumbnails at or after the constraining position are concealed to protect viewing value. This spatial differentiation in display quality resolves the contradiction between providing content outline information and preserving viewing experience.
2Loss of information
If all extracted representative images are displayed, then complete content coverage is achieved, but sensitive content such as story developments or endings is prematurely exposed
Solution Approach 1:
The patent implements preliminary action by pre-determining a constraining position in the video content timeline before display. This constraining position is set in advance to prevent exposure of sensitive content such as story developments or endings. The system proactively conceals thumbnails at or after this position, resolving the contradiction between achieving complete content coverage and preventing spoiler exposure.
3Speed
If video content data of long total time is played back using fast-forward function, then playback speed is increased, but a great deal of time is still needed
Solution Approach 1:
The patent applies dimensionality change by introducing a temporal dimension to the thumbnail display function. Instead of simply displaying thumbnails statically, the system dynamically controls thumbnail visibility based on the current playback position relative to the constraining position. This temporal dimension allows users to quickly navigate to the constraining position and understand content structure without watching entire long videos, significantly reducing total time needed while maintaining playback speed.
Data Source
AI summary
According to one embodiment, an electronic apparatus comprises an image extraction module, an image list display process module, and a playback module. The image extraction module extracts a plurality of representative images from a sequence of video content data, and outputs time stamp information which is indicative of a time point at which each of the plurality of extracted representative images appears in the video content data. The image list display process module displays, on a display area, a list of representative images appearing in a period from a start position to a predetermined display constraining position of the sequence of the video content data among the plurality of extracted representative images, and constrains the display of the representative images appearing after the display constraining position among the plurality of representative images. The playback module plays back the video content data in response to input of a playback request event.
