Problems solved by technology

[0008] However, at this time, the working cloud storage system has started to receive real-time surveillance video. If the surveillance video transmitted by the backup cloud storage system is too large at this time, it will occupy a large bandwidth of the working cloud storage system, thereby affecting the normal transmission of real-time surveillance video.

Abstract

Embodiments of the invention provide a video transmission method, device and system. The method comprises the steps of receiving a video transmission task; searching local monitor videos for video clips matched with the video transmission task; creating a clip backup task for each video clip, and creating a data transmission thread; and according to the clip backup tasks and local transmission parameters, transmitting each video clip to a working cloud storage system through the data transmission thread, wherein the transmission parameters are determined and sent to a first CVS by a CMS according to network bandwidth information sent by a CVM of the working cloud storage system. According to the video transmission method, device and system, the transmission parameter for transmitting a monitor video by the cloud storage system is adjusted and backed up in real time according to network bandwidth information of the working cloud storage system, so as to guarantee that the real-time monitor video is transmitted normally.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video transmission method, device and system. Background technique [0002] Cloud storage is a new concept extended and developed on the concept of cloud computing, and it is an emerging network storage technology. Specifically, it can use functions such as cluster applications, network technology, or distributed file systems to integrate a large number of different types of storage devices in the network to work together through application software to jointly provide a system for data storage and business access functions. [0003] In the field of video surveillance, a video capture device can send the captured surveillance video to a cloud storage system for storage. And, usually, in order to ensure that the surveillance video can be stored normally and avoid the loss of the surveillance video, multiple cloud storage systems can be arranged, one of which is...
