The Streaming Media forwarding service subsystem uses video multi-level forwarding technology, realizes the transmission step by step of video image；
Streaming media service subsystem obtains the video flowing specified, and rational management is carried out according to user right, by video flowing in order, accurately
Be forwarded to application video user, meet multi-user concurrent retrieve for examination certain all the way real-time video the needs of.
The central dispatching service subsystem is responsible for dispatching streaming media service subsystem, video equipment control subsystem and led to
Letter control service subsystem work, realize video retrieve for examination, video storage, directory, equipment control function.
Reception " central dispatching service subsystem " is uniformly controlled instruction by the video equipment control service subsystem, is entered
Row analytic uniform, instruction conversion is carried out for distinct device and protocol rule, the recognizable instruction of generation equipment, is sent to front end
Equipment, realize and the isomery headend equipment such as encoding device, decoding device, head is uniformly controlled.
The client-end subsystem is responsible for the communication with interface service subsystem, realizes that user transfers the function of video, together
The authority distribution for safety certification and the video control that Shi Shixian videos call.
On the one hand the interface service subsystem will be docked with each service subsystem, transmission video, which is had access to and controlled, to be referred to
Order, heartbeat instruction is transmitted, history video is downloaded and played, and on the other hand, is provided OCX controls to client software subsystem and is connect
Mouthful, realize that the video in user interface is called and controlled, history video playback functionality.
Beneficial effect caused by the present invention includes two aspects：
The invention is by modes such as level of confidentiality, certification, fixed port forwardings, to realize the information system with concerning security matters network environment
The information of system exchanges and provides solution, meets under concerning security matters network environment to transmission of video, the requirement for controlling, checking；
By rational resource allocation policy, the video realized under the limited concerning security matters network environment of bandwidth is adjusted for the invention
Read, there is certain realistic meaning.
