Video viewing method and system of Internet video monitoring system

Abstract

The invention discloses a video viewing method of an Internet video monitoring system. The method comprises the following steps: the video monitoring and controlling platform of an Internet video monitoring system transmits commands to each front-end equipment transmit stream in advance, and notifies the front-end equipment to send video stream to a stream media server; a video viewing client-side sends viewing request corresponding to appointed front-end equipment to the video monitoring and controlling platform when the video of the appointed front-end equipment is required to be viewed; the video monitoring and controlling platform notifies the stream media server to give out the received video stream of the appointed front-end equipment to the video viewing client-side according to the viewing request. In addition, the invention also discloses an Internet video monitoring system. The technical proposal can shorten the time delay for viewing the video.

Description

technical field [0001] The invention relates to network video monitoring technology, in particular to a video viewing method of a network video monitoring system and a corresponding network video monitoring system. Background technique [0002] In the video surveillance system, compared with the traditional analog video surveillance system, because the IP network video surveillance system has the advantages of convenient transmission, easy storage, and flexible management, it is used more and more. figure 1 It is a schematic diagram of the structure of the current network video surveillance system, such as figure 1 As shown, the system mainly includes: front-end equipment, monitoring and management platform, streaming media server and client. Among them, video acquisition front-end equipment mainly includes: video surveillance camera, IP camera (Camera), digital video server (Digital Video Server, DVS), digital video recorder (Digital Video Recorder, DVR), and video encoder...

Problems solved by technology

In the fifth step, the client receives the video stream forwarded by the streaming media server and decodes it for viewing. This step usually requires a delay of tens of milliseconds

[0005] It can be seen that the current network video surveillance system must perform the above five steps of operation every time the user wants to view the video image, and the third step operation will be delayed by more than one or two hundred milliseconds, so that the network video surveillance system is much faster than the traditional one. The analog video surveillance system has a large delay, and the processing delay of real-time video has increasingly become a key factor affecting people's choice of network surveillance system
