Problems solved by technology

Generally speaking, the bottleneck of the physical device running the storage service program is the network interface or the hard disk speed, while the CPU and memory are just the opposite. Only a small proportion of resources are used and they are not well utilized. This is quite resulting in a certain degree of waste of resources

Embodiment Construction

[0034] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0035] In the existing video surveillance system, the storage service program mainly stores audio and video data in local disk space, mounted network storage devices such as disk arrays, and cloud storage devices. Regardless of the storage medium, it is mainly based on the operating system file creation, reading and writing, and deletion methods, and the media data and index data are respectively written into the corresponding files. The data information of each collection device is stored in multiple pairs of data files and index files with associated relationships.

[0036] figure 1 It shows a schematic flowchart of a method for improving the storage efficiency of...

Abstract

The embodiment of the invention discloses a method and a device for improving the storage efficiency of audio and video data in a video surveillance system. The method comprises the following steps: alocal file database is established, wherein the local file database is used for recording the correspondence relationship of the encoding and collecting equipment information, the data file information and the time information of the audio and video data; when the storage service program in the video surveillance system stores the audio and video data of the encoded acquisition device into the data file, storing the time period information of the audio and video data in the local file database. The embodiment of the invention can improve the storage efficiency and the performance of the audioand video data of the video monitoring system on the premise that the system environment and the storage medium are not changed.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of video surveillance, and in particular to a method and device for improving storage efficiency of audio and video data in a video surveillance system. Background technique [0002] The existing video surveillance system has a special storage service program to complete the storage of video surveillance data. The storage service program stores the received audio and video data in a local disk or a mounted storage device. [0003] The data storage method of the storage service program is mainly based on file operations. When the audio and video data of a new front-end encoding and acquisition device needs to be stored, the storage service program will create a new file on the disk. Acquisition device, one encoding and acquisition device usually corresponds to multiple video files. When the video recording plan of the encoding acquisition device to be stored expires, the encoding acqu...
