Video Playback Interface for Missed Plot Text Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in accurately controlling video playback progress when fast-forwarding, leading to cumbersome operations and inefficiency in reading plot descriptions due to varying video durations and fixed progress bars.
Innovation Solution
A display method and apparatus that automatically detects plot-related text in a video and displays it on a secondary interface when the primary interface misses such text, without requiring manual rewinding, by determining similarity and character count thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the user manually drags the video progress bar to rewind and browse text again, then the user can access the missed plot description text, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The system performs preliminary detection of plot description text during video playback and stores it in advance. When the user needs to review the text, the system can quickly retrieve and display the pre-detected text without requiring manual rewinding, thus resolving the contradiction between accessing missed information and ease of operation
Solution Approach 2:
The patent introduces an intermediary mechanism (text detection and storage system) that bridges the gap between the video playback and text review needs. This intermediary stores plot description text separately and allows users to access it independently from the video progress bar operation, eliminating the cumbersome manual dragging action
2Loss of information
If the user drags the video progress bar to rewind, then the user can view the text at the previous playback node, but the fixed progress bar length causes inaccurate video duration correspondence
Solution Approach 1:
The patent introduces an intermediary text storage and retrieval system that decouples the text access function from the video progress bar. This intermediary maintains accurate correspondence between text nodes and their temporal positions, allowing precise access to plot descriptions without relying on the fixed-length progress bar that causes measurement imprecision
Solution Approach 2:
The system replaces the mechanical progress bar dragging mechanism with an automated text detection and retrieval mechanism. Instead of relying on visual progress bar manipulation that suffers from fixed-length limitations, the system uses computational detection to accurately identify and retrieve text at specific playback nodes, thereby improving measurement precision
3Productivity
If the video playback speed is fast, then the video can be played back efficiently, but the user cannot finish browsing the text before the video picture switches
Solution Approach 1:
The system performs preliminary detection and storage of plot description text during the fast video playback. By detecting and storing the text in advance before the user needs to review it, the system enables the user to quickly access the text without slowing down the video playback, thus resolving the contradiction between high productivity and information completeness
Solution Approach 2:
The patent enables continuous video playback at high speed while simultaneously performing text detection and storage in the background. The useful action of text retrieval can be performed continuously without interrupting the fast video playback, allowing both high productivity and complete information access to coexist

AI summary
A display method and an electronic device are provided. The method includes: when a first interface includes a first playback picture, determining whether a first character string satisfies a target condition. The first playback picture includes the first character string, and the first playback picture is a playback picture of a target video at a first playback node. The method further includes when the first character string satisfies the target condition, displaying a second character string on a second interface. A second playback picture includes the second character string, and the second playback picture is a playback picture of the target video at a second playback node. The second playback node is a previous playback node of the first playback node.
