Problems solved by technology
But the size of each video slice is fixed, and only transcoding is the only way to reduce video capacity
[0009] The above methods start to solve the problem of optimal storage and scheduling of the content in the video library from all levels, but they do not effectively solve the storage bottleneck faced by the existing monitoring system

Embodiment Construction
[0032] Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
[0033] figure 1 One type of existing video surveillance system is described. In a current system architecture of an intelligent monitoring system, at least a plurality of monitoring cameras 1 and a plurality of front-end servers 2 are included in the front end of the system. Wherein each front-end server 2 will support multiple monitoring cameras 1 at the same time. According to different functions of intelligent video analysis supported, the number of surveillance cameras 1 supported by each front-end server 2 is different. The front-end server 2 interacts with the monitoring center 4 through a dedicated network or the Internet 3 . The monitoring center 4 manages the entire system, and there will be a storage center 5 at its back end, where all monitoring videos are stored. The monitoring terminal 7 can perform monitoring work at the monitoring center ...

The invention provides a video storage control and optimization method and device, and a video monitoring system. The video storage control and optimization device includes a combined strategy execution control unit, a video stream reception unit, a video processing unit and a video multiplexing unit, wherein the combined strategy execution control unit receives a storage combination strategy corresponding to a video channel from a front server or analysis server; the video stream reception unit receives a video stream from the front server or the analysis server; the video processing unit processes the received video stream according to the storage combination strategy; and the video multiplexing unit arranges and combines the video stream processed by the video processing unit to generate an integral video fragment which is finally stored, and sends the integrated video fragment to video databases of different levels according to the storage combination strategy and thus provides convenience for storage.
Description
technical field [0001] The invention relates to a video storage control and optimization method and its device, and a video monitoring system, in particular to a method and device for optimizing video storage in the video monitoring system. Background technique [0002] Video surveillance system has been widely used in social security. In various cities, hundreds of thousands of cameras are deployed every year. Generally, the competent department of video surveillance needs to store the video content obtained by the video surveillance system for a certain period of time (such as three months to two years), and the storage of these video contents will bring a great burden to the operator of the video surveillance system. . In view of the huge data volume of video content, some video surveillance systems use centralized storage, which will require a large investment in network and central storage; some systems use fully distributed storage, using front-end DVR and other equi...
