Abstract
The invention discloses a 3G (The 3rd Generation Telecommunication) wireless video monitoring implementation method and a 3G wireless video monitoring system based on RTP (Real Time Protocol) and RTSP (Real Time Streaming Protocol), which relate to the technical field of video monitoring. According to the invention, standard real time streaming media transmission protocols of the RTSP and the RTP are adopted, the RTSP is used for protocol control, the RTP is used for transmitting video data, a video viewing request is sent to a video server by a client through the RTSP, the video data can be transmitted to the video server through the RTP by a front end module after a command of the video server is received, and the video data is directly transferred to the client by the video server through the RTP. The 3G wireless video monitoring implementation method and the 3G wireless video monitoring system, disclosed by the invention, have the advantages that the expandability is strong, the packet loss cannot happen due to a TCP (Transmission Control Protocol)-based RTP mode, the video jitter of the client is small, the mosaic is less, and the network flow cost of a user is reduced.
Description
Technical field:
The invention of this reality relates to technical field of video monitoring, relates in particular to a kind of wireless video monitoring implementation method and system.
Background technology:
Traditional video monitoring adopts the cable video monitor mode mostly, its monitoring business is subject to the restriction of the external environment conditions such as place and equipment, and the operation and maintenance cost is higher, fast development along with mobile communication technology, the particularly arrival in high speed 3G epoch, in the video surveillance applications field, utilize wireless network to carry out the long-distance video data transfer, more and more in the mode that substitutes traditional cable video monitoring, existing a lot of video monitoring all is to adopt UDP to come transmitting video data, because the UDP packet loss is large, unstable, cause video jitter large, mosaic is many, poor effect, and some router can forbid udp protocol, causes video data can not arrive client, and the wireless flow expense is high.
Summary of the invention:
In order to solve the existing problem of background technology, the invention provides a kind of 3G wireless video monitoring implementation method based on RTP and RTSP, comprise that step is as follows:
Client sends to video server by the RTSP agreement need to check video request;
Video server sends the transmission of video instruction by RTSP agreement forward end module;
Front-end module is received the video server instruction, prepares video resource, and the notice video server is prepared to receive;
Front-end module passes through the Real-time Transport Protocol transmitting video data to video server;
After video server is received video data, be left intact, directly be transmitted to client by Real-time Transport Protocol.
Described front-end module can be controlled according to network condition code check and the quality of video flowing.
The inventive method adopts RTSP and the RTP real time streaming agreement of standard, comes agreement control with RTSP, comes transmitting video data with RTP, these two agreement extensibilities are strong, easily access, and real-time is good, can compatible multiple client, no matter be PC or mobile phone, use browser just can watch the video of front-end module, and adopt RTP based on the mode of TCP, the client video jitter is little, mosaic is few, and packet loss not in the transmission course has reduced the user network flow.
The present invention also provides a kind of 3G wireless video monitoring system based on RTP and RTSP, it comprises video acquisition device, 3G module, communication network, video server, client, described video acquisition device connects the 3G module, the 3G module is connected with video server by communication network, and video server is connected with client by communication network again.
The RTSP agreement is adopted in the control of described client and video server and video server and front-end module, and the video data transmitting of client and video server and video server and front-end module adopts Real-time Transport Protocol.
Described front-end module can be controlled code check and the quality of video flowing timely according to network condition.
Described video data both can be preserved backup at front-end module, can preserve backup at streaming media server again, can also back up in client storage.
Method and system of the present invention are applicable to 3G wireless transmission and cable video transmission, adopt the control of RTSP and RTP standard agreement and transmission, and extensibility is strong, RTP is based on the mode of TCP, packet loss not, and the client video jitter is little, mosaic is few, reduces the user network campus network.
Description of drawings:
Fig. 1 is an embodiment schematic diagram of system of the present invention.
Embodiment:
The performing step of the inventive method is as follows:
1, at first front-end module is set up TCP and is connected to video server, then with the front-end module information registering to video server, connect in order to keep TCP, front-end module upgrades the information of oneself at set intervals to streaming media server.
2, video server is preserved front-end module information and is safeguarded.
3, client can be wireless terminal or catv terminal, when needs are checked the video of front-end module, send request by wireless or wire communication network to video server first, video server sends instruction by wireless or wire communication network with RTSP forward end module.
4, front-end module is received the video server request, prepares video resource, and the notice video server is prepared to receive.
5, front-end module by wireless or wire communication network using Real-time Transport Protocol transmitting video data to video server.
6, after video server is received video data, be left intact, directly be transmitted to wireless terminal or catv terminal by wireless or wire communication network Real-time Transport Protocol.
Fig. 1 is an embodiment of system of the present invention, as shown in Figure 1 also, a kind of 3G wireless video monitoring system based on RTP and RTSP, it comprises video acquisition device, 3G module, communication network, video server, client, described video acquisition device connects the 3G module, the 3G module is practiced level by communication network and video server, and video server is connected with client by communication network again.
Described client can be catv terminal or wireless terminal, client sends the transmission of video instruction by wireless or wire communication network to video server, video server sends the transmission of video instruction to video acquisition device again, video acquisition device sends video data to the 3G module after receiving instruction, the 3G module sends video data to video server by wireless or wire communication network, and video server is given video data transmitting wireless or cable customer's end by wireless or wire communication network again.
