Clip Playback Control for Fast Index Display of Split Video Files
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video reproduction systems face inefficiencies when handling divided video files, leading to prolonged loading times and user inconvenience due to the large number of divisions, especially when files are recorded in short units.
Innovation Solution
A reproduction control apparatus that distinguishes between different types of clips (formed by divided or non-divided video files) to optimize information display and reproduction control, allowing for rapid index display and reduced waiting times by skipping unnecessary file loading for certain types of clips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video files are divided into many small units for recording, then the recording flexibility and user-defined short time unit requirement are satisfied, but the time required to load all files and acquire information increases significantly
Solution Approach 1:
The video recording system divides video files into multiple segments based on file system constraints (first type) or user-defined short time units (second type). The determination means identifies whether a clip consists of multiple divided files, and the control means selectively loads only necessary information for divided clips while performing full loading for non-divided clips, thus resolving the contradiction between flexible segmentation and loading efficiency
Solution Approach 2:
The system changes the parameter of file division strategy by introducing two distinct types: first type divided by file system upper limit and second type divided by user-defined short time unit. This parameter change allows the system to adapt the loading strategy based on the clip type, optimizing the balance between recording flexibility and information acquisition speed
2Loss of information
If all video files are loaded to acquire complete information, then accurate information display is ensured, but the operation time and user waiting time increase
Solution Approach 1:
The control means extracts and loads only the necessary minimum information required for displaying indices of divided video files, rather than loading all file information. This selective extraction maintains sufficient information completeness for the display function while significantly reducing loading time and improving operational responsiveness
Solution Approach 2:
For second type clips (user-defined short time unit divisions), the system performs partial action by loading only essential information rather than complete file information. This partial loading approach is sufficient for the intended display purpose and eliminates unnecessary loading operations, thereby improving ease of operation without compromising information adequacy

AI summary
A reproduction control apparatus for controlling reproduction of a clip formed by not less than one video file recorded in a recording medium, comprises a determination unit that determines whether the clip is a clip of a first type formed by a plurality of video files divided by a predetermined unit or a clip of a second type different from the clip of the first type, and a control unit that controls, for the clip determined to be the clip of the second type by the determination unit, to display information based on the not less than one video file forming the clip, and for the clip determined to be the clip of the first type by the determination unit, not to display information based on the plurality of video files forming the clip.
