Abstract
A video recording system and method for archiving surveillance videos from multiple cameras includes storing video clips in files on a storage medium. The system segments incoming videos into time-ordered clips and stores them in a hierarchical directory structure organized by camera and time period. When storage capacity reaches a threshold, the system identifies older video clips based on age or retention policies, designates their files as recycled files, and moves the recycled files to a recycle directory. As new video clips are captured, they are stored in the recycled files rather than deleting the old files and creating new files. The system supports different retention periods for different cameras.
Core Innovation
The video recording system receives videos captured by multiple video cameras, segments each video into time-ordered clips, and stores each clip in a corresponding video file. When storage reaches a threshold usage capacity, the controller identifies files representing older clips and designates them as recycled video files. Subsequent newest clips are stored in selected recycled files, reusing existing files rather than creating new files.
The method and computer-readable-medium embodiments likewise store time-ordered clips from multiple cameras in respective files, designate files for older clips as recycled, and store subsequent newest clips in those existing files. The partial content does not include the background section, so the problem as framed in that section is not explicitly described; the supplied description states that reuse avoids requiring file deletion and creation.
Claims Coverage
The relevant claims include three independent claims encompassing three inventive features: a video recording system (claim 1), a method for storing videos (claim 11), and a non-transitory computer-readable medium storing instructions (claim 20).
Capacity-triggered recycling of video files
The system segments videos from multiple cameras into time-ordered clips and stores each clip in a corresponding video file. When the storage medium reaches a threshold usage capacity, the controller identifies files representing older clips and designates them as recycled video files, then stores subsequent newest clips in selected recycled files.
Reuse of recycled files in a video storage method
The method stores time-ordered clips from multiple cameras in respective files, identifies and designates files representing older clips as recycled, and stores subsequent newest clips in selected recycled files rather than creating a new file for each newest clip.
Instructions for storing clips in recycled files
The non-transitory computer-readable medium stores instructions that cause processors to store time-ordered clips in respective files, identify and designate files representing older clips as recycled, and store subsequent newest clips in selected existing recycled files rather than creating new files.
The three independent claims cover a system, a storage method, and executable instructions that designate files for older video clips as recycled and reuse those files for subsequent newest clips.
Stated Advantages
Reusing existing video files reduces disk I/O, CPU use, and processing time, and increases recording throughput.
Documented Applications
Archiving videos captured by multiple video cameras in a video surveillance system.
