Caption-Based Video Preview on Progress Bars for Richer Context
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video content preview methods provide insufficient information due to reliance on static video frames, which fail to represent voice information and context, limiting the presentation of video content.
Innovation Solution
A video content preview method that displays a progress bar component in the video-playing interface, allowing users to move the bar to trigger the display of captions corresponding to target timestamps, thereby presenting video content in the form of captions, enhancing the amount of information shown.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a video frame of a target jumping position is decoded and presented for preview, then the user can preview the video content at the target position, but the amount of information presented is small and the video content cannot be sufficiently presented
Solution Approach 1:
The patent uses caption text as a simplified copy or representation of the video content instead of displaying the actual video frame. The caption captures the essential information (dialogue, narration) in textual form, providing a more information-dense preview without requiring full video decoding. This resolves the contradiction by presenting more information (caption text + timestamp) while avoiding the complexity of decoding and rendering video frames for preview purposes.
2Loss of information
If a video frame is displayed for preview, then the visual content can be seen, but voice information and context cannot be represented
Solution Approach 1:
The patent introduces caption text as an intermediary representation that bridges the gap between video content and information transmission. Instead of relying solely on visual video frames (which cannot convey voice information), the caption serves as a mediator that translates audio/visual content into textual form, preserving voice information and context while maintaining simple user interaction through the existing progress bar interface.
3Reliability
If the progress bar component responds to moving instructions by displaying video frames, then the preview function works, but the operation may produce unexpected jumps and resource consumption increases
Solution Approach 1:
The patent uses lightweight caption data (text with timestamp) instead of heavy video frame data for preview purposes. Caption information is much smaller in size and requires minimal processing resources to display, significantly reducing memory usage and CPU/GPU resource consumption. The caption is generated once and can be quickly rendered as text, avoiding the expensive video decoding process while maintaining preview functionality and operational stability.
Data Source
AI summary
The embodiments of the present disclosure provide a video content preview interactive method and apparatus, an electronic device, and a storage medium. A video-playing interface is displayed, a progress bar component is provided in the video-playing interface, and the progress bar component is used for displaying a playing progress of a target video played in the video-playing interface; a target caption corresponding to a target timestamp of the target video is displayed in response to a moving instruction for the progress bar component, where the moving operation indicates the target timestamp of the target video, and the target caption indicates video content of the target video at the target timestamp.
