Mobile Terminal Region Extraction for Continuous Video Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals struggle to continuously provide video data information to users when the output of the video data is limited, requiring users to temporarily stop and restart the video playback to view specific regions of interest.
Innovation Solution
A mobile terminal with a touch screen, user input unit, and controller that outputs list information for preset regions, extracts video data corresponding to selected regions, and forms control commands to display summary information over time, allowing continuous access to selected video data even when the main video playback is paused or terminated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mobile terminal limits the output of the reproduction screen, then the user can focus on specific regions or perform other tasks, but the user cannot continuously view video data information from the selected region
Solution Approach 1:
The patent segments the video information by extracting and displaying only the selected region of interest as summary information (thumbnails, key frames, or extracted video segments) rather than requiring the user to view the entire reproduction screen. This segmentation allows users to access specific video content independently of the main playback state.
Solution Approach 2:
The patent introduces an intermediary mechanism (the controller that extracts and processes video data) that creates summary information from the selected region. This intermediary allows the video information to be preserved and made accessible even when the original reproduction screen output is limited or terminated.
2Adaptability or versatility
If the user terminates the video output to perform other tasks, then the user can switch functions, but the user must restart playback to view the video again
Solution Approach 1:
The patent performs preliminary action by extracting and preparing summary information from the selected video region before the user terminates playback. This pre-extracted information remains available for quick access when the user returns, eliminating the need to restart playback from the beginning.
Solution Approach 2:
The patent maintains continuity of useful action by keeping the extracted summary information available even when the main video playback is terminated. The information extraction and availability continues independently, allowing seamless resumption without full playback restart.
3Loss of information
If the mobile terminal continuously plays video data, then the user can view the video, but the device consumes more energy and occupies the screen continuously
Solution Approach 1:
The patent applies partial action by extracting and displaying only the necessary summary information from the selected video region rather than continuously playing the entire video. This partial extraction provides sufficient information for user needs while consuming significantly less energy and screen occupancy.
Data Source
AI summary
A mobile terminal may continuously provide information corresponding to video data included in a region selected from a reproduction screen, even though outputting of the reproduction screen output on a touch screen is limited. The mobile terminal includes a touch screen configured to output a reproduction screen corresponding to video data, a user input unit configured to receive a user input limiting outputting of the reproduction screen, and a controller configured to output list information regarding a plurality of preset regions included in the reproduction screen when the user input is received, and extract video data corresponding to a selected region on the basis of a touch applied to the list information, wherein the controller may form a control command for outputting summary information corresponding to the extracted video data over time.
