Video Management Apparatus Storage Capacity Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video management systems cannot efficiently delete video data considering the acquisition state of statistics, leading to storage capacity issues and potential loss of necessary data.
Innovation Solution
A video management apparatus with a storage processing unit, determination unit, calculation unit, and deletion unit that analyzes video data groups based on storage capacity and maximum analysis time to determine when to delete data, ensuring that video data used for statistical analysis is prioritized and deleted accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If video data is continuously stored in storage unit, then storage capacity is utilized for long-term video retention, but storage capacity becomes insufficient and new video files cannot be stored
Solution Approach 1:
The system automatically deletes video data groups after statistical analysis is completed, recovering storage capacity for new video files. The deletion unit identifies and removes analyzed video data groups from the storage unit, enabling continuous operation without manual intervention while maintaining long-term retention capabilities.
2Quantity of substance
If video data is deleted based on time and frequency priority, then storage capacity is managed, but deletion does not consider the acquisition state of statistics
Solution Approach 1:
The determination unit checks whether statistical analysis has been completed on video data groups before deletion occurs. This preliminary verification ensures that video data is only deleted after the required statistical information has been fully acquired, preventing loss of incomplete or necessary statistical data while effectively managing storage capacity.
3Loss of information
If video analysis is performed to acquire statistics, then useful statistical information is obtained, but storage capacity is consumed during the analysis period
Solution Approach 1:
The system performs video analysis to acquire necessary statistical information, then automatically deletes the analyzed video data groups to recover storage capacity. This cycle allows continuous statistical acquisition while maintaining adequate storage availability for new video files, resolving the contradiction between information gain and storage consumption.

AI summary
A video management apparatus includes a storage processing unit configured to store, in a storage unit, video data received through a network, a determination unit configured to determine whether or not video data groups stored in the storage unit are analyzed based on a first period of time indicating a period of time until a free capacity becomes insufficient in the storage unit and a second period of time indicating a maximum analysis time required for analysis of the video data groups, a first calculation unit configured to analyze the video data groups to calculate a predetermined statistic in a case where it is determined that the video data groups are analyzed, and a deletion unit configured to delete the analyzed video data groups.
