Solution Overview

Problem

Current video preview methods in video-playing software provide insufficient information about video content at target positions, as they rely on static video frames that only represent image information and not voice, and fail to convey context before jumping to a new position.

Innovation Solution

A video content preview method that displays target captions corresponding to the first video position indicated by a moving operation on a progress bar component, using subtitle data generated from audio information, allowing continuous context display and decoupling video playback from preview operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If static video frames are used for preview, then the preview function can be implemented, but the information about video content is insufficient

Engineering Contradiction:
Improvevideo content informationVSAvoidpreview system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The preview information is segmented into multiple components: static video frame images and dynamic caption text. This segmentation allows the system to present different types of information (visual and textual) in a coordinated manner, thereby reducing information loss without requiring a completely new complex system

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent merges the static video frame display function with the dynamic caption display function into a unified preview interface. By combining these two elements, the system provides both visual and textual information about the video content at the target position, effectively reducing information loss while maintaining manageable system complexity

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If video frame decoding is performed for preview, then video content can be displayed, but playback may jump unexpectedly

Engineering Contradiction:
Improveplayback stabilityVSAvoidpreview operation smoothness
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent extracts the caption information from the video decoding process and presents it separately in the preview interface. This extraction allows the preview function to display video content information without requiring full video frame decoding, thereby preventing unexpected playback jumps while maintaining smooth preview operation

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The caption text serves as an intermediary element between the video content and the user. Instead of directly decoding and displaying video frames for preview, the system uses captions as a mediator to convey video content information, which reduces the risk of playback instability while maintaining ease of operation

Inventive Principle:
Principle #24Intermediary (Mediator)

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; corresponding target caption is displayed in response to a moving operation for the progress bar component, where the moving operation indicates of the target video, and the target caption indicates video content of the target video at the first video position. In response to the moving operation for the progress bar component, the video content at the video position corresponding to the moving operation is displayed in the form of caption.
