Video transmission method of the present invention, be used for subordinate's platform superior platform pushed information, may further comprise the steps: after described superior platforms registration, described superior platforms learns that described subordinate platform is online to (1) described subordinate platform by employing standard SIP flow process authentication mode; (2) dialog events of described subordinate's platform initiation, described subordinate platform sends NOTIFY to described superior platforms, and described superior platforms is informed in event; (3) to be pushed to the type of the message body of described superior platforms be XML to described subordinate platform; (4) the guarded region information in the described XML message body of propelling movement, described guarded region information has comprised geocoding, the display name of guarded region and the monitoring scene quantity of carrying; (5) push monitoring scene information, described monitoring scene information has comprised the total quantity of display name, active state and the video camera preset point of described monitoring scene; (6) push geocoding, preset point coding and the active state of the video camera that described monitoring scene comprises; (7) described superior platforms sends " 200 " to described subordinate platform, and the expression confirmation pushes complete.
Particularly, described guarded region is the subregion of transformer station, has the unique sign of the whole network; Described monitoring scene is the set of some video camera preset point of described guarded region, has the unique sign of the whole network.
Further, when pushing described guarded region and described monitoring scene information, can repeatedly push step by step; Each message length is less than the MTU value that configures on the network.
As preferably, described message length is less than 1400 bytes.
Further, described superior platforms is received when described subordinate platform pushes the described guarded region of coming and described monitoring scene information, if can't in the existing information in this locality, find the information of described guarded region, then return error code " 403 ", described subordinate platform pushes from last layer information after receiving described error code " 403 " again again.
Beneficial effect of the present invention is:
The present invention carries out differentiated control and realize the real time information transmission by the SIP gateway between upper and lower level by the mode of guarded region identification and the monitoring scene identification video monitoring information with camera collection, realizes that the concentrated message of different video monitoring systems is shared; By subordinate's platform scene setting information superior platform is pushed, solve the problem of the multiple setting of the interconnected Scene of multi-stage platform, realized that different level personnel carry out consistency and the instantaneity of unified video monitor to the key area when critical event, satisfied the growth requirement of video monitoring system for substation globalize, integration.
