Portable Terminal Video Preview Search Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inefficiency in searching for desired videos on portable terminals due to the reliance on thumbnail images, which may not adequately identify videos and require manual selection, decreasing video management efficiency.
Innovation Solution
Implementing a method and system for portable terminals to display video previews during search, allowing users to select and playback videos efficiently by setting a preview section, eliminating the need for manual video selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If thumbnail images are used for video identification during search, then device complexity is reduced and ease of operation is improved, but measurement precision and reliability of video identification deteriorate
Solution Approach 1:
The video content is segmented into a preview section (first predetermined time period) and the remaining portion. During search operations, only the preview section is displayed and played back, separating the identification function from the full video content. This segmentation allows efficient searching while maintaining adequate video identification capability.
Solution Approach 2:
Instead of displaying or playing back the entire video during search, a copy of the preview section is created and displayed. The controller plays back only this preview section when a search is performed, providing sufficient video identification without the complexity and time consumption of handling full video files.
2Measurement precision
If the entire video is played back during search, then video identification accuracy is improved, but loss of time and productivity deteriorate
Solution Approach 1:
The preview section is extracted from the full video content as a separate, manageable unit. The controller is configured to play back only this extracted preview section during search operations, eliminating the time-consuming process of playing back entire videos while maintaining sufficient accuracy for video identification and selection.
3Productivity
If manual selection of videos is required, then ease of operation is reduced, but device complexity is minimized
Solution Approach 1:
The system provides self-service by automatically playing back the preview section when a search operation is initiated. The controller detects the search input and automatically plays back the corresponding preview section without requiring manual video selection or complex user interactions, thereby improving video management efficiency while maintaining operational simplicity.

AI summary
A portable terminal and a method for managing videos in the portable terminal are provide increased efficiency in managing videos in the portable terminal. The portable terminal includes: a memory for storing at least one video and a preview thereof, a controller for playing back a preview of a video corresponding to a set preview section during a video search and, upon selection of a video, playing back the selected video; and a display unit for displaying, under control of the controller, the video preview and the video that are being played back. The method for managing videos in the portable terminal includes: displaying a list of at least one video preview on a first screen during a video search; playing back, on a second screen, a preview of a video corresponding to a set preview section; selecting the video corresponding to the video preview being played back; and playing back the selected video.
