The step of dispaly state：After being performed for control command, each broadcasting server will broadcast feedback of status to state
Feedback device, state feedback device shows the broadcast state of each broadcasting server in state display device.
Embodiment six：
The present embodiment is the improvement of above-described embodiment, is refinement of the above-described embodiment on control command.The present embodiment institute
The implementation procedure of control command is as follows in " performing the step of operating according to linkage possible table " for stating：
Linkage control device finds what can be communicated with the broadcasting server of pending action according to pending action message
Presentation controller, and the control command for controlling the broadcasting server is sent to the presentation controller.
The presentation controller sends control command to the broadcasting server of connection.
Broadcasting server receives control command, carries out corresponding scene change operation.
Control command is that, to complete a certain action, control broadcasting server performs the instruction that is, order of concrete operations.It is real
At this moment existing action can be acted the movement decomposition for many height with very complicated, and when creating linkage possible table, needs are
Each action or the IP of the order of son action specified control and control object.For example：Action to be achieved is by the service of broadcasting
The scenario B broadcasted on device B and the scene C broadcasted on broadcasting server C stop together.Can be two fields by the movement decomposition
Scape stops respectively, i.e., write two actions when the possible table that links is created：" broadcasting server B stops scenario B ", including broadcast service
Device B IP, cease and desist order；" broadcasting server C stops scene C ", includes broadcasting server C IP, ceases and desist order.Work as connection
When dynamic control device receives the two action messages, ceasing and desisting order of being specified in action can be sent respectively to two and broadcast clothes
Business device.And ceasing and desisting order for being sent to the server for broadcasting scenario B specifies the id information of scenario B.Clothes to broadcasting scene C
Ceasing and desisting order for business device transmission specifies scene C id information.The id information of scene is mark of the scene on broadcasting server.
Compound action can not also be decomposed, all on a broadcasting server be broadcasted for example, it is desired to realize
The wholly off action of scene, if there is a wholly off control command on this broadcasting server, then just only send out one
Bar control command just, i.e., creates an action in linkage possible table.If not provided, being accomplished by just broadcasting scene hair to be each
One, that is, create corresponding multiple actions in linkage possible table.
Finally it should be noted that being merely illustrative of the technical solution of the present invention and unrestricted above, although with reference to preferable cloth
Scheme is put the present invention is described in detail, it will be understood by those within the art that, can be to technology of the invention
Scheme（Such as server set number, setting, sequencing of step of each device etc. in coordinated signals end）Repaiied
Change or equivalent substitution, without departing from the spirit and scope of technical solution of the present invention.Method of the present invention can be worked out to answer
For the program of computer system, and run in computer network system of the present invention.
