Method for reducing cloud deck control delay in network video monitoring platform

Abstract

The invention relates to a method for reducing cloud deck control delay in a network video monitoring platform, and the method is technically characterized by comprising the following steps: (1) starting the network video monitoring platform, connecting the network video monitoring platform to a front-end device, and starting the shift detection function of the front-end device; (2) performing shift detection on each video previewing channel by the network video monitoring platform, thereby acquiring the motion state of the previewing video of each channel in real time; and (3) dynamically distributing the maximum code rate of each channel by the network video monitoring platform according to the motion state of the previewing video of each channel. The method provided by the invention has the advantages that the design is reasonable and the cloud deck control delay in the network video monitoring platform is reduced without improving the conditions of the current network and other hardware resources through utilizing the network video monitoring platform to acquire the motion state of the previewing video of each channel at real time, dynamically distribute the maximum code rate of each channel according to the priority of the motion state of the previewing video of each channel and dynamically manage the network resource.

Description

technical field [0001] The invention belongs to the field of video monitoring, in particular to a method for reducing the delay of pan-tilt control in a network video monitoring platform. Background technique [0002] The network video surveillance platform usually refers to the IP surveillance system platform used for specific applications in the field of security surveillance and remote monitoring, which enables users to realize video surveillance and video image recording through the IP network. The difference between the network video surveillance platform and the analog video surveillance platform is that the network video surveillance platform uses the IP network to transmit video and various information related to monitoring, instead of using point-to-point analog video cables for transmission. The network video surveillance platform can digitize video information and transmit it through a wired or wireless IP network, so that real-time monitoring and recording functi...

Problems solved by technology

In the high-definition network video surveillance platform, due to the large amount of data and the decoding is limited by hardware resources and other factors, it will cause delays in PTZ control

The existing network video surveillance platform distributes the delay time equally for each channel in terms of resource allocation. If the existing network and other hardware resources are not changed, the delay of PTZ control cannot be reduced.

If you want to reduce the delay of PTZ control, you need to open up a dedicated network for video data or divide the network bandwidth resources through switches and routers, and reserve dedicated bandwidth resources for video applications, which will result in a significant increase in resources and costs.
