Description
Technical field
The present invention proposes a kind of method by video monitoring system access video conferencing system, belongs to different agreement system and melts
Conjunction technology.
Background technique
With taking place frequently for Mass disturbance and natural calamity, the being scheduled commander based on the scene of the accident becomes governments at all levels
The important process of department.On this basis, it in addition to convening video conferencing system, is performed in unison with multidisciplinary, the superior and the subordinate's vertical component effect
Door carries out emergency together and links up except commander, it is also necessary to access the image of the video camera at scene, all convenient for more collaboration departments
Live video image can be viewed, convenient for making more accurate decision.But the standard that current video conferencing system uses
SIP/H323 signaling protocol and H264 video protocols, and the ONVIF of video monitoring system generallyd use and producer are privately owned
The video flowing of SDK, partial video monitoring producer also use privately owned video code model, are to sum up unable to complete video conferencing system
With the docking of video monitoring system；Third-party monitoring system can not namely be accessed in third-party video system.
Summary of the invention
The present invention proposes a kind of method by video monitoring system access video conferencing system, and the signaling of monitoring system is turned
The video flowing of monitoring system, is converted into the H264 video format of standard by SIP (session initiation protocol) signaling for changing standard into
(the 10th part MPEG-4, advanced video coding), and format of giving out a contract for a project is packaged into the UDP/RTP format of standard, it can be by third
The monitoring system of side is linked into the SIP video conferencing system of third party's standard.
The present invention adopts the following technical scheme:
A method of video monitoring system is accessed into one of video conferencing system, including following two method:
First method the following steps are included:
(1) server is scanned by ONVIF, will be provided with the camera discovery of ONVIF access capability, and connects camera；
(2) camera is logged on to video conferencing system by the method for dynamic SIP signaling by server；
(3) video conferencing system issues the SDP information for having step (2) dynamic SIP signaling to server；Then server
It saves the SDP information with step (2) dynamic SIP signaling and passes through " ONVIF/GetCapabilities and ONVIF/
GetVideoEncoderConfiguration/GetVideoEncoderConfiguratio nOptions " order obtains camera shooting
The media information of head；Then server generates the SDP information and replys 200OK to video conferencing system；
(4) video conferencing system receives 200OK, replys ACK to server；
(5) server receives ACK, and the RTSP broadcast address of the camera is obtained by GetVideoSources；Then
Server starts camera by RTSP Clien, and decodes the video flowing of the camera, is re-encoded as the H264 of standard
Video format is sent to video conferencing system by UDP/RTP then to the packet header video encapsulation RTP；It completes video monitoring system
System access video conferencing system；
Second method the following steps are included:
(1) server logs in camera by SDK/CLIENT_LoginEx2；
(2) camera is logged on to video conferencing system by the method for dynamic SIP signaling by server；Video conference
System issues the SDP information for having dynamic SIP signaling to server；Then server saves the SDP with dynamic SIP signaling and believes
Breath；Then server sends 200OK to video conferencing system；Video conferencing system receives 200OK, replys ACK to server；
(3) server receives ACK, passes through SDK/CLIENT_StartRealPlay/CLIENT_
SetRealDataCallBackEx starts camera, and decodes the video flowing of the camera, is re-encoded as the H264 of standard
Video format is sent to video conferencing system by UDP/RTP then to the packet header video encapsulation RTP；It completes video monitoring system
System access video conferencing system.
It is described that the packet header video encapsulation RTP is carried out according to the SDP information in above-mentioned technical proposal.The present invention relates to English
Text abbreviation paraphrase is shown in Table 1.
The english abbreviation paraphrase of the present invention of table 1
Access camera is converted into interior by first method of the present invention by the ONVIF agreement of video monitoring system standard
The control protocol in portion；The SDK development kit that second method is provided by monitoring producer, camera or monitoring system are converted into
Internal control protocol.The video stream transcoding that monitoring system is come out accesses video conference system at the H264 video format of standard
System, by the media parameter decoded video streams of video monitoring, and the SDP video parameter encapsulation to be come according to video conference is encoded to
Video format needed for video conference；The H264 video of standard is packaged into the RTP encapsulation of standard, accesses video conferencing system,
The SDP parameter to be come according to video conference, it is main to modify PT value/timestamp/sequence number.
Detailed description of the invention
Fig. 1 is the communication scheme of embodiment one video monitoring system and video conferencing system；
Fig. 2 is the communication scheme of embodiment two video monitoring systems and video conferencing system.
Specific embodiment
Embodiment one
With reference to Fig. 1, by monitoring the ONVIF agreement of manufacturer's standard, camera will be accessed and be converted into internal control protocol,
It is described as follows:
Server is scanned by ONVIF, will be provided with the camera discovery of ONVIF access capability, and is stepped on by account number cipher
Record and connection camera；This camera is logged on to video conferencing system by the method for dynamic SIP signaling by server, dynamic
SIP signaling is 21000；
Video conferencing system calls the SDP information with 21000 to server, and server saves SDP information, passes through routine
" ONVIF/GetCapabilities and ONVIF/GetVideoEncoderConfiguration/
The orders such as GetVideoEncoderConfigurationOptions " obtain the media information of camera, and server is based on this matchmaker
Body information generates SDP, and replys 200OK to video conferencing system；
Video conferencing system receives 200OK, replys ACK to server；Server receives ACK, passes through
GetVideoSources obtains camera RTSP broadcast address；Server starts camera by RTSP Client；
Server receives decoded video streams after camera video stream, and according to the SDP information video format of the negotiation, weight
The newly encoded H264 video format at standard encapsulates the packet header RTP, is sent to video conferencing system, main basis by UDP/RTP
SDP modifies PT value/timestamp/sequence number in the packet header RTP；
Video communication is successfully established.
Embodiment two
With reference to Fig. 2, camera or monitoring system are converted into inside by the SDK development kit provided by monitoring producer
Control protocol is described as follows:
Server logs in big magnificent equipment camera by SDK/CLIENT_LoginEx2；
This camera is logged on to video conferencing system system, dynamic SIP letter by the method for dynamic SIP signaling by server
Enable is 21001；
Video conferencing system calling with 21000 SDP information to server；Server saves SDP information；Server returns
200OK to video conferencing system video conferencing system reply ACK is answered to server；Server passes through big Hua Xianyou after receiving ACK
SDK/CLIENT_StartRealPlay/CLIENT_SetRealDataCallBackEx start camera, and get YUV
Video data；
Yuv data is packaged into H264 video format according to the SDP information by server, mainly according to the negotiation
SDP video parameter encapsulates the packet header RTP, is sent to video conferencing system by UDP/RTP；
Video communication is successfully established.
For ease of description, the system that this method is run becomes gateway.This method is by super fusion view networking system, my company
System, by the invention, the video monitoring system of different manufacturers or video camera are linked into our video conference system by we
In system, so that the participant of meeting in the communication process of video conference, can also be checked real-time captured by camera simultaneously
Picture is preferably linked up and is arranged convenient for making in the application scenarios such as emergency command scheduling/video working conference.
