Multimedia Playback Progress Recovery Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video playback systems fail to accurately return to a previous play time after unintended fast forwarding or rewinding, leading to degraded user experience due to the need for manual retrieval of play progress.
Innovation Solution
An information processing method and electronic device that detect and store play progress at specific times, allowing for accurate retrieval and playback from a previous play time through recovery operations, even after multiple fast forwards or rewinds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the video-locking function is activated to prevent misoperation, then the video cannot jump to another play time, but the user experiences inconvenience when needing to perform operations such as fast forward, rewind, or pause
Solution Approach 1:
The system performs preliminary action by automatically recording the play progress before a time adjustment operation occurs. When a user performs a time adjustment (fast forward/rewind), the system has already captured the previous play progress in advance, enabling automatic recovery without requiring the user to manually navigate back. This resolves the contradiction by preparing recovery data beforehand, maintaining both reliability and ease of operation.
Solution Approach 2:
The system implements feedback by detecting the time adjustment operation and automatically initiating a recovery process that returns the video to the previously recorded play progress. The system monitors the play progress bar interactions, identifies when a time adjustment occurs, and subsequently executes a recovery action to restore the original position. This feedback mechanism ensures the video returns to the correct play time automatically, eliminating the need for manual intervention while maintaining operational convenience.
2Ease of operation
If the user relies on memory to recall the current play time after misoperation, then the user can attempt to return to the correct play time, but the video cannot accurately return to the previous play time and multiple clicks are required
Solution Approach 1:
The system performs self-service by automatically recording and managing the play progress without requiring user intervention. The system continuously monitors the play progress bar, captures the play progress before time adjustments, and automatically executes recovery operations when needed. This eliminates the need for the user to rely on memory or manually click multiple times, as the system handles the entire process autonomously, improving both ease of operation and play time accuracy.
Solution Approach 2:
The system replaces the mechanical manual operation (user clicking on the play progress bar multiple times based on memory) with an automated electronic system. The system uses electronic detection to identify time adjustment operations, automatically captures play progress data, and executes recovery actions through electronic control rather than manual user input. This substitution eliminates the imprecision and inconvenience of memory-based recovery, achieving accurate play time restoration.
3Reliability
If the user performs multiple operations to return to the correct play time, then the user can eventually achieve the desired play time, but the video viewing process becomes inefficient and inconvenient
Solution Approach 1:
The system performs preliminary action by continuously recording the play progress before each time adjustment operation. When a user fast forwards or rewinds the video, the system has already captured the previous play progress in advance, enabling immediate and accurate recovery without requiring multiple sequential operations. This preliminary data capture eliminates time loss by allowing the system to restore the correct play time in a single automatic action, improving both reliability and time efficiency.
Solution Approach 2:
The system implements feedback by detecting time adjustment operations and automatically initiating recovery to the previously recorded play progress. The system monitors play progress bar interactions, identifies when a time adjustment occurs, and subsequently executes a feedback recovery action to restore the original position. This automated feedback loop eliminates the need for multiple manual operations, reducing the time spent on play time recovery while maintaining accurate restoration.

AI summary
Disclosed is an information processing method and an electronic device capable of playing a multimedia file. The method includes when detecting a first operation of adjusting a play time of a multimedia file from a first time to a second time different from the first time in the process of playing the multimedia file, acquiring and storing a play progress of the multimedia file corresponding to the first time; and when detecting a second operation of a user, retrieving the play progress of the multimedia file corresponding to the first time and playing the multimedia file from the play progress corresponding to the first time in response to the second operation. With the method and electronic device, a video can accurately return to a play progress corresponding to a previous play time after a fast forward or rewind is performed in the process of playing the video.
