With the wide application of video monitoring system in various social safety, production, life and other fields, independent video system by using communication, coding, code encapsulation protocol is different, so that the image information cannot interconnection, form the information isolated island, seriously hinder the development of Internet application, to realize the sharing of image information system, in-depth study of the different protocols of information conversion become the key to solve the problem based on.
In this paper, in order to solve the above problems, the national standard "security video monitoring network system of information transmission, exchange, technical requirements" (GB28181-2012) used as the main object of study, in the monitoring system of digital network video analysis and based on the national standard to carry out the theoretical basis and technical principle on the conversion of the network, RTSP-SIP protocol for a detailed discussion and research. The main contents:
1 Comparative Analysis of the current domestic and foreign mainstream monitoring system adopts the protocol standards, such as the local standard in Zhejiang, China Mobile, China Unicom, the State Grid, the Ministry of education examination monitoring system, international enterprise standards organization ONVIF, PSIA and other standards, in agreement with national standard level to find out similarities and differences, the main problems need to solve network the transfer between control protocol, RTSP protocol and SIP protocol.
2, a detailed study of the SIP protocol, RTSP protocol, including the protocol format, structure, function, key is to confirm the mapping relationship between the protocol commands, lays the technology foundation for the.
3, I have carried on the further development of the open source system, the realization of the SIP protocol and RTSP protocol server functions. By writing the code to achieve the SIP protocol monitoring domain and SIP domain and RTSP domain monitor monitoring client, server, equipment registration, real-time monitoring, historical image playback, real-time control operation.
4, through the experiment building environment obtained the images between RTSP-SIP protocol monitoring domain interconnection and mutual control, and the communication protocol, the encoding format and type of test software for different control protocol, different media encapsulation format of the monitoring system for the verification and analysis, realized the standard monitoring system technology, and is proved to be effective conversion design module, and the foundation for the next step of Interworking Control Protocol, different media format of the monitoring system.
