The embodiment of the present invention relates to register flow path, logout flow path, the expired media bit flow process of cleaning, and media play flow process, by reference to the accompanying drawings above-mentioned each flow process is described in detail respectively below.

Referring to Fig. 1, be the registration process that the embodiment of the present invention provides, this process can be realized by Set Top Box.This flow process mainly comprises the following steps:

In step 100, receive the media file registration request that described application sends, in described playback of media files request, comprise the identification information of playing position information and application.

In step 101, according to the described identification information inquiry registration database of playing position information and described application, if identification information that determine to play position information and described application according to Query Result is unregistered (from step 102 to step 105) also, in step 108, the identification information of playing position information and described application is registered, hour of log-on corresponding with the identification information of described broadcasting position information and described application in described registration database is updated to current time.

Because being registered to the log-on message list of application plays position, broadcasting position information suffered, so in the identification information registration of applying, only the identification information of application need to be registered in the log-on message list of application plays position.

In step 107, according to described broadcasting position information inquiry policy database, to determine whether to download corresponding playback of media files strategy, if not, in step 109, from front end system, download playback of media files strategy corresponding to described broadcasting position information, if download successfully, in step 111, the more new state of playing playback of media files strategy corresponding to position information described in described policy database is set to upgrade complete, if failed download, in step 112, the more new state of playing playback of media files strategy corresponding to position information described in described policy database is set to upgrade.

If in step 102, according to Query Result, determine whether registration, if so, in step 103, the described identification information of playing position information and described application is registered in the log-on message list of application plays position.Wherein, when playing the application plays position log-on message list of position information registering, the identification information that request need to be carried out to the application of media file registration is registered in the log-on message list of application plays position, so just guaranteed the broadcasting position information of registration at least corresponding the identification information of an application.When Set Top Box receives the playback of media files request that application sends, can be by playback of media files corresponding to the broadcasting position information of carrying in request the identification information to the application of carrying in request.Having guaranteed to play media file corresponding to position information has at least the identification information of an application to play this media file.

If in step 105, the identification information of judgement application is registered in the information list of application plays position,, in step 106, upgrades the log-on message list of application plays position.

This is because the identification information playing position information likely can corresponding a plurality of application, so may occur playing position information registers in the log-on message list of application plays position, but playing a plurality of application corresponding to position information may occur, some application are registered in the log-on message list of application plays position, and application also in the log-on message list of application plays position, do not register.

In step 107, according to described broadcasting position information inquiry policy database, to determine whether to download corresponding playback of media files strategy, if,, in step 104, Set Top Box triggers from front end system and downloads playback of media files strategy corresponding to described broadcasting position information.

Wherein, a playback of media files strategy corresponding to the described broadcasting position information of Set Top Box triggering front end system download mainly comprises:

Set Top Box forward end system sends the request of obtaining playback of media files strategy, wherein in request, carry the position information of playing, front end system is according to the broadcasting position information of carrying in the request of receiving and request, by with play position information for playback of media files strategy send to Set Top Box.Further, to send the request obtain playback of media files strategy be to complete in the process of registration to Set Top Box forward end system.

Above-mentioned flow process article registration play the process of position information, wherein the process of registration completes before can sending to Set Top Box in application and playing media file request, this register method has guaranteed to be applied in to Set Top Box and has sent and play media file request, Set Top Box can not spend and judge whether to need to upgrade the playback of media files strategy of playing in the information list of position, directly remove to inquire about playback of media files strategy, then according to the authority of playback of media files strategy and application, the media file information corresponding to broadcasting position information of carrying in the broadcasting media file request that determines whether to send to application sends to application.

Also have a kind of method, the process of registration can be in First Contact Connections, to complete between application box Set Top Box.Adopt in this way, be applied in when sending broadcasting media file request to Set Top Box, Set Top Box can be sent response to application very soon, but the response that Set Top Box is sent may comprise two kinds of results: the one, and Set Top Box sends and plays media file corresponding to broadcasting position information carrying in media file request to application, another kind is that Set Top Box sends Empty Medium file to application.

Referring to Fig. 2, be the log off procedure that the embodiment of the present invention provides, this process can be realized by Set Top Box.This flow process mainly comprises the following steps:

In step 201, receive the media file de-registration request that described application sends, in described media file de-registration request, comprise the identification information that the described application of media file cancellation is carried out in described broadcasting position information and request.

In step 202, according to the described identification information inquiry registration database of playing position information and described application; In step 203, if determine that according to Query Result the identification information of described application and described broadcasting position information registers,, in step 204, judge in described registration database, whether in addition the identification information of other application is corresponding with described broadcasting position information except the identification information of described application.

If so, in step 209, the described broadcasting in list of application corresponding to position information from described registration database, deletes the identification information of described application.

Wherein, the identification information of application is only registered in the information registering information list of application plays position, so the identification information of the application of registering only delete application plays position information registering information list when deleting in.

If in step 203, if determine identification information and the not registration of described broadcasting position information of described application according to Query Result,, in step 211, finish log off procedure.

If in step 204, if do not have the identification information of other application corresponding with described broadcasting position information in described registration database except the identification information of described application, in step 205, if the more new state in policy database is not exit state,, in step 211, finish log off procedure.

Wherein, the identification information of a plurality of application herein, can comprise and the identification information of the application in step 203 also can comprise that other times are registered to the identification information of the application of application plays position log-on message list.

Such as, the broadcasting position information of A company is when registering for the first time, not only the broadcasting position information registering of Yao Jiang A company is in the log-on message list of application plays position, and the identification information that request need to be carried out to the application of media file registration is registered in the log-on message list of application plays position, the identification information that the application of media file registration is carried out in the request is here assumed to be 1 satellite TV, so when the broadcasting position of A company information registering arrives the log-on message list of application plays position, the identification information of the channel application of 1 satellite TV is also registered in the log-on message list of application plays position.

But, if application sends media file registration request to Set Top Box, what in request, carry is the identification information of the broadcasting position information of A company and the application of 2 satellite TVs that the media file registration of A company is carried out in request, because the broadcasting position information of A company has been registered in the log-on message list of application plays position, and the identification information of the application of 2 satellite TVs is not registered in the log-on message list of application plays position, so, when Set Top Box is received after the media file registration request of application transmission, only the identification information of the application of 2 satellite TVs need to be registered in the log-on message list of application plays position.

If in step 205, if the more new state in policy database is exit state, in step 206, if the more new state in policy database is not new state more,, in step 210, the more new state in policy database is exit state.

In table 3, record a UPDATESTATUS field, the content of the demonstration of UPDATESTATUS field is 0,1,2 and 4, and wherein, 0 represents not yet more new state; 1 is representing more new state; 2 represent that renewal is complete; 4 represent exit state.

If in step 206, if the more new state in policy database is new state more,, in step 207, the more new state in registration database is set as to exit state.

In step 208, from described registration database, delete the described identification information of playing position information and described application, and from described policy database, delete described playback of media files strategy corresponding to position of playing.

Wherein, registration database comprises application plays position information registering information list and plays position information list, if only have the identification information of an application to be registered in the information registering information list of application plays position, more new state in broadcasting position information list corresponding to the identification information of this application is exit state, this is play to full detail corresponding to position information and delete, and play full detail corresponding to position information, mainly comprise the information in the information registering information list of application plays position and play the information in the information list of position.

Above-mentioned log off procedure can carry out in set-top-box opening, can be also to complete after Set Top Box is received the media file de-registration request of application transmission.If Set Top Box is power-off suddenly in log off procedure, in start next time, Set Top Box can, according to open state, complete and nullify action so.When Set Top Box is when nullifying, if application sends playback of media files request, and what in request, carry is to nullify the request of playing position information, and Set Top Box can be returned to sky information to application.

Referring to Fig. 3, be the process of obtaining, resolve playback of media files strategy that the embodiment of the present invention provides, this process can be realized by Set Top Box.This flow process mainly comprises the following steps:

In step 301, the more new state of playing playback of media files strategy corresponding to position information described in described policy database is set to upgrade; In step 302, broadcasting position information is sent to front end system, the playback of media files strategy that receiving front-end system is returned; Wherein, the first forward end system of Set Top Box sends playback of media files strategy request, in request, carried the position information of playing, front end system is according to the solicited message of receiving and play position information, and playback of media files strategy corresponding to broadcasting position information with receiving sent to Set Top Box.

In step 303, if Set Top Box receives playback of media files strategy from front end system; , in step 304, resolve and receive playback of media files strategy, obtain the new position information list of playing.In step 305, if new, play position information list effective; , in step 306, travel through the list of current media file broadcast strategy;

Wherein, playback of media files Policy List comprises a plurality of playback of media files strategies.

In step 307, relatively whether with the list of current media file broadcast strategy whether new media file broadcast strategy have same policy; If have, in step 308, Delete Expired playback of media files strategy.

Wherein, a plurality of playback of media files strategies in playback of media files Policy List and the new media file broadcast strategy obtaining are compared one by one, if will have the playback of media files strategy identical with new media file broadcast strategy in playback of media files Policy List, think that the playback of media files strategy in playback of media files Policy List does not change, and deletes above-mentioned new media file broadcast strategy so; If will there is no the playback of media files strategy identical with new media file broadcast strategy in playback of media files Policy List, think that new media file broadcast strategy is newly-increased playback of media files strategy, need to add new media file broadcast strategy in playback of media files Policy List to.

In step 309, whether traveled through the list of current media file broadcast strategy, if so, in step 310, judged whether newly-increased playback of media files strategy; If have,, in step 311, upgrade the playback of media files strategy of playing in the information list of position.

As shown in table 3, in playback of media files Policy List, there is a field SCHEDULEID, each playback of media files strategy has a unique SCHEDULEID, if a playback of media files strategy SCHEDULEID exists in new playback of media files strategy, in current playback of media files strategy, do not exist, this is newly-increased playback of media files strategy; If playback of media files strategy SCHEDULEID does not exist in new playback of media files strategy, in current playback of media files strategy, exist, this playback of media files strategy is expired playback of media files strategy; If playback of media files strategy SCHEDULEID exists in new playback of media files strategy and current playback of media files strategy simultaneously, this playback of media files strategy does not upgrade.

If in step 303, if Set Top Box does not receive playback of media files strategy from front end system; , in step 311, the more new state of playing playback of media files strategy corresponding to position information described in described policy database is set to upgrade.

This is because in the process of the playback of media files strategy sending in Set Top Box receiving front-end system, if the unexpected power-off of Set Top Box, or there is other accident, the situation that the playback of media files strategy that likely causes Set Top Box front end system not to be sent receives completely.

If from front end system request playback of media files strategy, when front end system is returned as sky to Set Top Box, retain all information of this broadcasting position information, then the more new status field in playback of media files Policy List is made as and is upgraded.

If in step 305, if new, play position information list invalid; , in step step 311, the more new state of playing playback of media files strategy corresponding to position information described in described policy database is set to upgrade.

If in step 307, relatively whether with the list of current media file broadcast strategy whether new media file broadcast strategy have same policy; If nothing,, in step 312, thinks that playback of media files strategy is without change., in step 313, new media file broadcast strategy is deleted.

If in step 309, whether traveled through the list of current media file broadcast strategy, if not,, in step 306, travel through current media file broadcast strategy table.

If in step 310, judged whether newly-increased playback of media files strategy; If nothing,, in step 314, adds newly-increased playback of media files strategy at playback of media files Policy List, from front end system, download the media file of newly-increased playback of media files strategy.

In step 315, the more new state of playing playback of media files strategy corresponding to position information described in described policy database is set to upgrade complete.

Upgrade complete only presentation medium file broadcast strategy and added in policy data, but presentation medium file has not been downloaded complete.

So, when playback of media files Policy List has added after newly-increased playback of media files strategy, the media file that this newly-increased playback of media files strategy is corresponding does not also obtain from front end system, so Set Top Box needs forward end system to send media file request, in request, carried the position information of playing, front end system is according to the solicited message of receiving and play position information, and broadcasting position media file corresponding to information with receiving sent to Set Top Box.

Above-mentionedly obtain, resolve playback of media files strategy and finally determine whether from media file corresponding to front end system downloads of media file broadcast strategy, can be to complete in registration, also can be after registration completes, the time period of Set Top Box free time completes, and the embodiment of the present invention does not limit obtaining, resolve the concrete time period of playback of media files strategy.

Referring to Fig. 4, be the playback of media files process that the embodiment of the present invention provides, this process can be realized by Set Top Box.This flow process mainly comprises the following steps:

In step 400, receive the playback of media files request that application sends, in described playback of media files request, comprise the identification information that the application of playback of media files is carried out in an information of playing and request, described broadcasting position information is used to indicate reproduction time section and the channel of media file.

In step 401, according to described identification information inquiry of playing position information and described application, play position information table.

In step 402, whether channel ID is in white list; If do not exist, in step 403, according to current time traversal playback of media files Policy Table.

Judge that channel ID whether in white list, is to determine according to the information of the WHITELISTINGFO field in table 2.Such as: the media file of A company is play in the request of 1 satellite TV, according to the information of the WHITELISTINGFO field in table 2, first judge that 1 satellite TV is whether in white list list, wherein in white list list, recorded the channel list that can not play media file, if 1 satellite TV is present in white list list, represent that 1 satellite TV can not play media file, Set Top Box Hui Xiang 1 satellite TV sends a null response.If 1 satellite TV is not present in white list list, represent that 1 satellite TV can play the media file of A company.
