Monitoring association turn server receive the first tune stream request after, can according to this first adjust stream request judge it is subsequent will Push monitoring code stream is that monitoring association turns server or third party's monitor supervision platform.Also, if it is third party's monitor supervision platform, So third party's monitor supervision platform may be that monitoring code stream is pushed in a manner of TCP, it is also possible to monitoring code stream is pushed in a manner of UDP, It therefore can be in a manner of further judging third party's monitor supervision platform push monitoring code stream.

In a preferred embodiment, step 502 may include: that monitoring association turns server and judges target monitoring resource mark Know corresponding target monitoring resource, if third party's monitor supervision platform that connection is pushed in a manner of TCP；If monitoring association turns server and sentences It is yes for breaking, it is determined that push monitoring code stream is the third party's monitor supervision platform pushed in a manner of TCP.

In the embodiment of the present invention, first adjusts stream to request to may include target monitoring resource identification, terminal iidentification, terminal user The information such as number.Monitoring association turns the corresponding pass that monitoring resource identification with monitoring resource connection equipment can be pre-saved in server System, such as connection equipment may turn server for monitoring association, it is also possible to be third party's monitor supervision platform.For third party's monitor supervision platform The mode of third party's monitor supervision platform push code stream can also be pre-saved, for example mode may be TCP mode, it is also possible to be UDP mode.Monitoring association turn server receive the first tune stream request after, target can be determined according to the corresponding relationship pre-saved The connection equipment of the corresponding target monitoring resource of resource identification is monitored, if connection equipment is third party's monitor supervision platform, into one Step checks the mode of the third party's monitor supervision platform push code stream pre-saved.

Step 503, if monitoring association turns server and is judged as YES, the TCP between third party's monitor supervision platform is established Connection.

If monitoring association, which turns server, judges that push monitoring code stream is that monitoring association turns server itself namely target prison The connection equipment of the corresponding target monitoring resource of control resource identification is that monitoring association turns server, then monitor association turn server be not necessarily into Row specially treated can be based on view networking protocol based on the monitoring code stream of view networking protocol encapsulation target monitoring resource, and by this Monitoring code stream be sent to view networked server, then adjust stream request by sending it to above-mentioned transmission first depending on networked server Terminal, user can check corresponding monitor video at the terminal.

Judge that push monitoring code stream is that the third party's monitoring pushed in a manner of UDP is put down if monitoring association and turning server Platform, and monitoring association turns Server Default and can receive what third party's monitor supervision platform was pushed in a manner of UDP in the embodiment of the present invention Monitor code stream.Therefore, monitoring association turns server without carrying out specially treated, and it is flat third party's monitoring can be received according to default behavior The monitoring code stream based on udp protocol encapsulation of platform push, and the monitoring code stream based on udp protocol can be converted to based on view The monitoring code stream of networking protocol will be sent to view networked server based on the monitoring code stream depending on networking protocol, then be networked by view Server sends it to the terminal that stream request is adjusted in above-mentioned transmission first, and user can check corresponding monitoring view at the terminal Frequently.

Judge that push monitoring code stream is that the third party's monitoring pushed in a manner of TCP is put down if monitoring association and turning server Platform, then monitoring association and turning server can establish TCP connection between third party's monitor supervision platform.

In a preferred embodiment, step 503 may include: that monitoring association turns server creation TCP Client, and builds Connection in vertical TCP Client and third party's monitor supervision platform between preset TCP server.It can specifically include following steps:

A1, monitoring association turn server and obtain the IP address of preset TCP server and end in third party's monitor supervision platform Message breath.

It, can be preparatory in third party's monitor supervision platform if third party's monitor supervision platform pushes monitoring code stream in a manner of TCP TCP server is set, push monitoring code stream is carried out by the TCP server.Monitoring association turns server can monitor from third party (Internet Protocol, the network protocol) address IP and the port information of wherein TCP server, port letter are obtained in platform Breath may include port numbers, port name etc..
