Subtitle Segmentation for Efficient Multimedia Playback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multimedia playback control methods are inefficient and lack interactivity, requiring users to drag an anchor multiple times to find desired segments, making it cumbersome to control playback progress.
Innovation Solution
The method involves dividing subtitle information into segments corresponding to time tags, displaying a subtitle alignment indicatrix and skip option, allowing users to select and play specific segments by triggering the skip option, thereby determining the playback start time and adjusting the multimedia file's playback progress efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users drag the anchor in the playing progress bar multiple times to find desired segments, then the user can locate the target position, but the operation efficiency is low and the process is cumbersome
Solution Approach 1:
The subtitle information is divided into multiple subtitle segments, each corresponding to a specific time tag. The subtitle display interface is segmented to show different subtitle segments in different regions, allowing users to directly select from predefined segments rather than manually dragging through the entire progress bar. This segmentation enables direct access to target positions without iterative trial and error.
Solution Approach 2:
The subtitle display interface acts as an intermediary between the user and the multimedia playback. By displaying subtitle segments with their corresponding time tags and allowing selection through the interface (e.g., dragging within the subtitle region), the system mediates the playback control process, translating user intent directly into precise playback position changes without requiring multiple anchor drags.
2Ease of operation
If users manually drag the anchor to control playback progress, then the playback position can be adjusted, but the interactivity is poor and the process is not simple or convenient
Solution Approach 1:
The subtitle display interface dynamically responds to user operations. When the user drags within the subtitle display region, the system dynamically updates to show the corresponding subtitle segment and time tag, and dynamically adjusts the playback progress bar anchor to the selected position. This dynamic behavior makes the interaction more intuitive and adaptable to user needs compared to static anchor dragging.
Solution Approach 2:
The system provides self-service by automatically calculating and displaying the corresponding time tags and playback positions based on user selection within the subtitle interface. When users select a subtitle segment, the system automatically determines the target playback position and adjusts the progress bar accordingly, eliminating the need for users to manually calculate or estimate positions.
3Loss of information
If the subtitle display interface shows detailed subtitle information, then users can identify desired segments, but the interface complexity increases
Solution Approach 1:
Different regions of the subtitle display interface have different functions and visual qualities. The interface is designed with local quality variations where subtitle segments are displayed with distinct visual characteristics, time tags are shown in specific formats, and interaction zones are clearly differentiated. This local quality differentiation helps users identify functional areas without overwhelming the entire interface with uniform complexity.
Solution Approach 2:
The interface adds temporal dimensionality by displaying time tags alongside subtitle segments, allowing users to perceive both content and timing information simultaneously. The subtitle segments are organized in a dimensional layout that maps to the temporal structure of the multimedia content, enabling users to navigate through time by visual inspection of the subtitle sequence rather than linear dragging.

AI summary
A method for controlling multimedia playing, an apparatus thereof and a storage medium are provided according to the present disclosure, which relates to the field of terminal technology. The method includes: dividing subtitle information of a multimedia file into multiple subtitle segments, where each of the multiple subtitle segments corresponds to a time tag; triggering to play a selected subtitle segment of the subtitle information; obtaining a playing start time of the selected subtitle segment according to a time tag corresponding to the selected subtitle segment; and playing the multimedia file from the playing start time.
