When described watch-dog to display process video synthesis platform between analogue transmission route use information be busy time, wall failure information in feedback.
Below in conjunction with Fig. 4, video synthesis platform optical fiber cascade management embodiment of the method provided by the invention is described in detail.
Step 1, distribute a unique number for the video synthesis platform of each optical fiber cascade, and configure the numbering of the video synthesis platform of the father node of the video synthesis platform of each optical fiber cascade.
With reference to the optical fiber cascade form of the video synthesis platform shown in Fig. 1, Fig. 2.In this step 1, unique number is distributed to each video synthesis platform of optical fiber cascade, such as, in Fig. 1, distribute numbering 001 to video synthesis platform A, video synthesis platform B distributed to numbering 002, video synthesis platform C distributed to numbering 003, video synthesis platform D distributed to numbering 004, distribute numbering 005 to video synthesis platform E, these numberings are uniquely corresponding with video synthesis platform.Configure the numbering of the video synthesis platform of the father node of the video synthesis platform of each optical fiber cascade, such as, in Fig. 1, the father node of video synthesis platform B and video synthesis platform D is video synthesis platform A, and video synthesis platform A be numbered 001, so the numbering of the video synthesis platform of the father node of video synthesis platform B and video synthesis platform D is 001, in like manner, the video synthesis platform of the father node of video synthesis platform C be numbered 002 (referring to video synthesis platform B), the video synthesis platform of the father node of video synthesis platform E be numbered 004 (referring to video synthesis platform D).
It should be noted that in the video synthesis platform of all optical fiber cascades, there is no the video synthesis platform of father node, the numbering of its father node video synthesis platform is configured to 0.There is no the video synthesis platform of father node, be the root node video synthesis platform in the video synthesis platform of optical fiber cascade, the video synthesis platform F in such as, video synthesis platform A and Fig. 2 in Fig. 1.In the embodiment of the present invention, the numbering of the father node video synthesis platform of root node (namely not having father node) video synthesis platform is configured to 0, in order to represent that this video synthesis platform does not have father node.
By distributing the numbering of all video synthesis platforms of optical fiber cascade in above-mentioned steps 1 and the configuration of father node video synthesis platform numbering, the cascade connection (all can be obtained the numbering of its father node video synthesis platform by the numbering of each child node video synthesis platform) between all video synthesis platforms just determining optical fiber cascade and topological structure.The analogue transmission route link information that can be like this between later step configuration video synthesis platform is ready.
