Table four
Fig. 5 has shown the flow process of present embodiment.As shown in Figure 5, present embodiment to the method that the life cycle of using manages is:
Step 501: the identification module of set-top box receives the starting command from user input device, and according to starting command application is started.
In this step, set-top box starts the method for using and is: set-top box changes incident according to starting command generation state, and the event attribute that described state changes incident comprises television terminal ID and uses ID; The application manager of set-top box listens to described state and changes incident, obtains television terminal ID and uses ID; Described application manager is according to television terminal ID inquiry television terminal management database and determine application data base ID; According to application data base ID and application ID inquiry application data base, obtain the apply property in the application message corresponding, and start application according to apply property with using ID.
In the practical application, server also can send to set-top box and start utility command, and its method is: the starting command that server will carry service ID and application ID sends to set-top box, and set-top box directly obtains service ID and uses ID from starting command; Application manager is according to service ID inquiry television terminal management database and determine application data base ID; According to application data base ID and application ID inquiry application data base, obtain the apply property in the application message corresponding, and start application according to apply property with using ID.
In the practical application, after application start, set-top box will be carried out the process of using, such as realizing mutual between user and the server.
Step 502: the identification module of set-top box receives the pause command from user input device, and suspends using according to pause command.
In this step, the method that set-top box realize to suspend is used is similar to step 501, and it distinguishes what only be to carry out is pause command, repeats no more herein.
Step 503: the identification module of set-top box receives the reset command from user input device, and according to starting command application is restarted.
This step is also similar substantially to step 501, just carries out reset command, repeats no more herein.
Step 504: the application manager reception is ceased and desisted order from server, and stops to use according to ceasing and desisting order.
In this step, the method that application manager stops to use is: server will carry service ID and use ceasing and desisting order of ID and send to set-top box, and set-top box directly obtains service ID and uses ID from cease and desist order; Application manager is according to service ID inquiry television terminal management database and determine application data base ID; According to application data base ID and application ID inquiry application data base, obtain the apply property in the application message corresponding, and stop to use according to apply property with using ID.
In the practical application, user input device also can send to set-top box and cease and desist order, and its method is similar to step 501, no longer is described in detail herein.
In a word, no matter server or user input device can start, suspend, restart and stop application, the life cycle of using is managed.Certainly, in the practical application, can also repeatedly application be suspended and restart, i.e. execution in step 502 and step 503 repeatedly.Then determine as for the number of times of carrying out repeatedly by the actual conditions that application is controlled.In the practical application, can to using time-out and restarting, perhaps only to using time-out, not that is to say that execution in step 503 after starting application, perhaps step 502 and step 503 are not carried out yet.
Certainly, in the practical application, set-top box also can provide a plurality of services simultaneously to the Digital Television of a multi-screen, its method is similar substantially to present embodiment, its difference only is that the orientation management database for the corresponding relation between record screen ID, service ID and the application data base ID, no longer is described in detail herein.
The method of Application Example one and embodiment two, set-top box can change according to the state of server or user input device orders the change that realizes application state in a plurality of current service.
Application Example three, set-top box can manage the life cycle of using in a plurality of current service.
In the practical application, the reason that changes application state also comprises following three kinds of situations: (1) server issues application message to set-top box, and described application message comprises the application controls symbol of more correcting one's mistakes.(2) explorer of set-top box generation resource lacks incident.(3) terminal input equipment handed over service sends the handed over service order to set-top box.
For first kind of situation, server provides in the process of service and application to the user, all application in service, the service, application messages of using etc. can be handed down to set-top box, and set-top box then is recorded in application message in the application data base.If set-top box is in the process that realizes certain application, in the process of using in operation, server issues the new application message of this application again to set-top box, and new application message comprises the application controls symbol different with former application message, then server can utilize the change application controls to accord with the state that changes application, and its method is:
The new application message that X1, set-top box will receive is recorded in the application data base, promptly upgrades application data base;
X2, application data base generation state change incident, and its event attribute comprises uses ID and application data base ID;
X3, application manager listen to state and change incident, according to application data base ID and application ID inquiry application data base, obtain and use the corresponding application message of ID, and realize that according to the apply property in the application message application controls accords with the change of indicated application state.
Such as: at server in the application message that set-top box issues, the value of the application controls of the former application message of the 1st application symbol is " self-starting " in the 2nd service, new application controls symbol value is " stopping ", and it is in 2 the application subdata base, promptly to use subdata base for the 2nd that the application message of all application in the 2nd service is kept at application data base ID value.When set-top box changed to " stopping " according to the new application message that receives with the application controls symbol, application data base changed incident with the generation state, and using the ID value in the event attribute of this state change incident is 1, and application data base ID value is 2.Application manager listens to this state and changes incident, inquire about the 2nd application subdata base according to application data base ID and application ID, obtain the apply property of the 1st application, again with the apply property of the 1st application destroy () function as the parameter call application proxy, thereby realize changing the purpose of application state, promptly stop the 1st application in the 2nd service.
In the practical application, application manager is the inquiry application data base in real time.If server has issued the application message of application controls symbol for " self-starting " to set-top box, set-top box is recorded in this application message in the application data base.When application manager inquired application controls symbol for the application message of self-starting, application manager can start corresponding application according to the apply property in this application message, promptly call application proxy start () function
For second kind of situation, explorer can detect the resource operating position in real time in the set-top box, when definite resource is not enough, influences when the user provides the effect of serving or using, can produce resource and lack incident, the event attribute of this incident comprises resource ID and location ID etc.Application manager listens to resource and lacks incident, with inquiry orientation management database and the definite and corresponding application data base ID of location ID, the minimum application of application message medium priority of described application subdata base is determined and stopped to the inquiry application subdata base corresponding with application data base ID again.
How to detect the resource operating position as for explorer, and when resource is not enough, produce resource and lack incident and then belong to prior art, repeat no more herein.
For the third situation,, can cause that also set-top box changes the state of using when user input device sends the handed over service order to set-top box.The form of handed over service order described here is identical to set-top box transmit status change order with user input device, can be level signal or light signal.The method that the handed over service order that set-top box sends according to user input device changes application state is:
Y1, set-top box identification module obtain location ID according to the handed over service order, again service ID corresponding with location ID in the orientation management database is updated to the service ID that obtains from server in advance, and the generation event attribute comprises the location database update event of locating ID.

| Television terminal ID or screen ID | Service ID | Application data base ID |
| ... | ... | ... |
Table five
In the practical application, when handed over service, server can be handed down to set-top box with all application in the service ID of serving, service is corresponding, the service and application message etc., set-top box will be upgraded service ID in television terminal management database or the screen management database according to the service ID that obtains, and produce television terminal management database or screen management database update incident.
The application data base creative management module of Y2, set-top box listens to the location database update event, obtains corresponding application data base ID and the service ID with location ID from the orientation management database.
Y3, application data base creative management module are upgraded the pairing application subdata base of application data base ID according to application data base ID and application message, and producing the application data base update event that event attribute comprises application data base ID, described application message is the application message corresponding with service ID that obtains from server in advance.
Y4, application manager listen to the application data base update event, whether have the application that is moving in the pairing application data base of application subdata base ID after judgement is upgraded according to application data base ID, if having, then do not deal with; Otherwise, the application that stops to move according to apply property.
In the practical application, an application can only be present in the service, promptly binds with service.When service is switched, also need to be stopped with the application of service binding, i.e. the state of this application is changed and is halted state.Application also can exist with a plurality of services in, promptly not with certain service binding.When service was switched, if in the service after switching this application is arranged also, then this application can continue to carry out.
