Video managing method and device

Abstract

The invention provides a video data storage utilization and video data managing method and device. The video data storage utilization method includes: creating a super block in the super block area of a disk, creating disk abstracts in the abstract area of the disk, creating disk data blocks in one-to-one correspondence to the disk abstracts in the data area of the disk, wherein each disk abstract includes channel number fields and starting time fields, and the channel number of video managing equipment corresponding to the video data stored in the disk data blocks corresponding the disk abstracts are stored in the channel number fields; when a video data storage request is received, selecting idle disk data blocks for data storage, and recording the information of the video data in the disk abstracts corresponding to the data blocks. By the method, the problem that video data cannot be stored when one disk fails in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of video storage, in particular to a method and device for video data storage planning and video data management. Background technique [0002] With the continuous development of video surveillance technology, various video camera equipment and video management equipment are widely used, such as network camera IPC and network video recorder NVR. Therefore, how to store and manage a large number of captured videos is a problem worthy of attention. [0003] The current video block storage method is to allocate an independent storage space for each video camera device on the disk of the video management device. Once the storage space is allocated, its storage location and space size have been determined and will not be changed. This storage space does not allow other video camera devices to write. Moreover, each camera will index and store video in its own allocated storage space. Therefore, when a certain d...

AI Technical Summary

Problems solved by technology

Therefore, when a certain disk on the video management device is pulled out, the storage space on the disk cannot be used, and the video recording device allocated the disk storage space cannot continue to store video, resulting in low reliability of video storage , thus affecting the integrity of the video surveillance

The existing block storage technology solutions cannot realize the dynamic allocation of storage space for video camera equipment, and the flexibility and scalability are poor

[0004] At present, the block storage technology builds a secondary index for the divided storage space on the disk, and saves the index data in the database through inspection. The establishment of the database requires a large FLASH space, and each inspection and retrieval needs to read the index, resulting in There are many disk read and write operations, and the speed is relatively slow
