Clip Playback Metadata Control for Faster Video File Browsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video file reproduction systems face inefficiencies due to long loading times when files are divided into small units, leading to user inconvenience during information acquisition and reproduction.
Innovation Solution
A reproduction control apparatus that determines the type of clip (first or second type) and controls information display accordingly, allowing quick display of information for clips of the second type without loading all files, thereby reducing waiting times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If video files are divided into small units for recording, then the user can record longer videos and manage file sizes better, but the time required to load and display information increases significantly
Solution Approach 1:
The patent extracts only the necessary information (such as file metadata, duration, file size) from the divided video files without loading the entire file contents. This allows the system to display essential information quickly while maintaining the ability to handle multiple divided files, thus resolving the contradiction between managing many small files and minimizing loading time.
Solution Approach 2:
The system performs preliminary actions by pre-processing and storing metadata information about divided video files during the recording phase. This preliminary preparation enables rapid display of file information without requiring full file loading during playback, effectively reducing loading time while supporting divided file structures.
2Loss of information
If all divided video files are loaded to display information, then complete information can be acquired, but the user experiences long waiting times
Solution Approach 1:
The patent applies partial action by loading only the necessary portion of file information (metadata, basic properties) rather than complete file contents. This partial loading strategy provides sufficient information for user decision-making while significantly reducing loading time and improving operational convenience.
Solution Approach 2:
The system introduces an intermediary layer (metadata information) that stands between the user and the actual video files. This intermediary provides essential file information without requiring full file loading, thus maintaining information usefulness while improving response speed and user convenience.
3Adaptability or versatility
If video files are divided by a short recording time unit, then the recording flexibility is improved, but the number of files increases leading to slower information acquisition
Solution Approach 1:
The patent segments the information acquisition process into two parts: lightweight metadata loading and optional full file loading. This segmentation allows the system to quickly handle multiple divided files by loading only essential information, maintaining high productivity even when dealing with numerous short recording units, while preserving recording flexibility.

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.
