Video stream distribution method and device, management server and video monitoring system

Abstract

The embodiment of the invention provides a video stream distribution method and device, a management server and a video monitoring system. The management server calculates step-by-step distribution parameters according to the number of current stream taking paths of the first streaming media server, the number of paths of the preset specification and the number of monitoring devices which are not distributed by the last-level streaming media server in the monitoring devices to which the acquired video streams belong, wherein the larger the step-by-step distribution parameters are, the more deeply the first streaming media server needs to be scheduled to distribute the video stream of the first monitoring equipment to the upper-level streaming media server. For a large-distribution application scene, a plurality of levels of streaming media servers are arranged in the video monitoring equipment, and for a video stream of one path of monitoring equipment, continuous expansion of the distribution path number of one path of video stream is realized through distribution of the plurality of levels of streaming media servers; therefore, the distribution performance of the video monitoring system to one path of video stream is improved.

Description

technical field [0001] The present application relates to the technical field of video surveillance, and in particular to a method and device for distributing video streams, a management server and a video surveillance system. Background technique [0002] With the development of video technology and network technology, the application of video surveillance system based on streaming media forwarding technology is more and more extensive. The system structure of common video surveillance system is as follows: figure 1 As shown, the video monitoring system includes a streaming media server, monitoring equipment, clients, decoders, storage servers, etc. The streaming media server obtains video streams from the front-end monitoring equipment, then copies and distributes the video streams to the storage server. Since the storage requirement in the monitoring system is 24 / 7 real-time storage, the video stream that is stored and distributed to the storage server always exists. If ...

Problems solved by technology

[0004]However, the number of channels that a streaming media server distributes to one video stream is often fixed, for example, a streaming media server distributes one video stream to 10 channels at most, In the scenario where there is a secondary streaming media server, the video surveillance system distributes up to 100 video streams for one video stream, which limits the distribution performance of the video surveillance system for one video stream
