Problems solved by technology

[0004] (1) If two or more types of videos appear at the same time, a video file must be saved for each type, which wastes disk space;
[0005] (2) If alarms and alarm releases occur frequently, many small video files will be generated, and their creation and deletion will easily generate disk fragments and reduce the operating efficiency of the system
[0007] Using the above scheme, the user can conveniently operate the required video content according to the task or time, which greatly facilitates the user's use; but the above scheme does not completely solve the shortcomings of the existing technology

Embodiment 1

[0042] see figure 1 , the present invention discloses a block storage system for multi-type video files, the storage system prepares a video disk space for video recording in advance, the size and location of the video disk space are specified by the user; the disk space is divided into more low-level Subdirectory, create block file again in described subdirectory; In each subdirectory, create a configuration file (the tracking information of described configuration file can include: the free block quantity of current directory, the minimum free block number, the number of each block usage) to track the usage of all block files in the current directory; when recording, generate a hard link file pointing to the block file in the recording directory, when the length of the video exceeds the size of the block file, then allocate the next one to it block file until the end of this recording; store the video information in the database for users to query and watch; store the inform...

Embodiment 2

[0066] The difference between this embodiment and Embodiment 1 is that in this embodiment, step 2 in the method of Embodiment 1 may not be included, that is, there is no need to divide the disk space into more lower-level subdirectories.

[0067] In this embodiment, video recording disk space is prepared in advance for video recording; block files and a configuration file are created in the disk to track the usage of all block files; when video recording, a hard link file pointing to block files is generated; when video recording When the length exceeds the size of the block file, the next block file will be assigned to it until the end of the video recording; the video information will be stored in the database for users to query and watch; the video block information will also be stored in the database; make a copy A table of correspondence between recordings and recording blocks, which lists one or more recording block files corresponding to one recording, or multiple record...

Embodiment 3

[0069] A video recording software is installed on a certain DVR. When the software is running, the video files are usually stored separately according to the video recording time and video channel. When the video recording starts, the file is created, and when the user issues a delete video command, the file is deleted.

[0070] Now, the solution of this embodiment is to prepare all video disk space (its size and position are specified by the user) for video recording in advance, and divide this space into file blocks of equal size for unified management; in actual application, The disk space can be further divided into more lower-level subdirectories, and block files are created in these subdirectories, and the subdirectories are named in a numbered manner; these block files are named in a BlockXXX (numbered) manner.

[0071] In each subdirectory, create a configuration file to track the usage of all blocks in the current directory. The tracking information includes: the numbe...

Abstract

The invention discloses multi-type video file block storage system and method. The method comprises the following steps of: preparing a video disk space for a video in advance; establishing block files and a configuration file in the disk so as to track the use conditions of all the block files; during recording a video, generating a hard link file directing to the block files; when the length ofthe video exceeds the size of a block file, distributing a next block file for the video until the video ends; storing the information of the video into a database for a user to inquire and watch; storing the information of video blocks into the database; and making a corresponding relation table of the video and the video blocks, wherein the table lists out one or more video block files corresponding to a video or a plurality of videos corresponding to a video block. The invention can effectively improve the utilization rate of the video disk of the user, thereby saving the disk resources.

Description

technical field [0001] The invention belongs to the technical field of surveillance video management, and relates to a system for storing video files in blocks, in particular to a system for storing multi-type video files in blocks; at the same time, the invention also relates to a storage method for the system for storing multi-type video files in blocks . Background technique [0002] The general process of the current recording is that after the recording task condition is triggered, a new recording task is created in the corresponding monitoring channel or an ongoing recording task is modified for recording. According to different trigger conditions, the recording is divided into the following three types: manual recording, scheduled recording, alarm recording; and a recording file has only one recording type. [0003] In this way, the following problems exist: [0004] (1) If two or more types of videos appear at the same time, a video file must be saved for each type...
