The identification information of road application is also registered in the log-on message list of application plays position.
But if sending media file registration request using to set top box, what is carried in the request is the broadcasting position of company A
Information and request carry out the identification information of the application of 2 satellite TVs of company A media file registration, due to the broadcasting position information of company A
Have already registered with the log-on message list of application plays position, and the identification information of the application of 2 satellite TVs is not registered to application plays
In the log-on message list of position, so, after set top box is received using the media file registration request sent, it is only necessary to by 2 satellite TVs
The identification information of application 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 plan
More new state slightly in database is not more new state, then in step 210, the more new state in policy database is note
Pin-shaped state.
Record has a UPDATESTATUS field in table 3, and the content of the display of UPDATESTATUS fields is 0,1,2
With 4, wherein, 0 represents not yet more new state；1 represents more new state；2 expression renewals finish；4 represent exit state.
If in step 206, if the more new state in policy database is more new state, in step 207,
More new state in registration database is set as exit state.
In a step 208, the mark letter of the broadcasting position information and the application is deleted from the registration database
Breath, and playback of media files strategy corresponding to the broadcasting position is deleted from the policy database.
Wherein, registration database includes application plays position information registering information list and plays position information list, if only
The identification information of one application is registered in the information registering information list of application plays position, when the identification information of the application is corresponding
The more new state played in the information list of position is exit state, then deletes full detail corresponding to the broadcasting position information, and is broadcast
Putting full detail corresponding to an information mainly includes the information in the information registering information list of application plays position and plays position information
Information in list.
Above-mentioned log off procedure, it can carry out when set-top-box opening or be received in set top box using transmission
Media file de-registration request after complete.If set top box powers off suddenly in log off procedure, then next time start when
Wait, set top box can complete cancellation action according to open state.When set top box is being unregistered, if application sends media
File playing request, and what is carried in asking is to nullify the request for playing position information, set top box can return to empty letter to application
Breath.
Referring to Fig. 3, for the process provided in an embodiment of the present invention for obtaining, parsing playback of media files strategy, the process can
Realized by set top box.The flow mainly comprises the following steps：
In step 301, playback of media files strategy corresponding to the information of position will be played described in the policy database
More new state is arranged to update；In step 302, position information will be played and is sent to front end system, receiving front-end system is returned
The playback of media files strategy returned；Wherein, first end system sends playback of media files strategy request to set top box forward, in the request
Carry and play position information, front end system according to the solicited message that receives and broadcasting position information, by with the broadcasting position information that receives
Corresponding playback of media files strategy is sent to set top box.
In step 303, if set top box receives playback of media files strategy from front end system；Then in step 304, solve
Analysis receives playback of media files strategy, obtains newly playing position information list.In step 305, if newly playing position information list has
Effect；Then within step 306, current media file broadcast strategy list is traveled through；
Wherein, playback of media files Policy List includes multiple playback of media files strategies.
In step 307, whether new media file broadcast strategy is compared with being in current media file broadcast strategy list
It is no to have same policy；If so, then in step 308, delete expired playback of media files strategy.
Wherein, by multiple playback of media files strategies in playback of media files Policy List and obtained new media file
Broadcast strategy compares one by one, if will have in playback of media files Policy List and new media file broadcast strategy identical media text
Part broadcast strategy, then it is assumed that the playback of media files strategy in playback of media files Policy List does not change, then will be above-mentioned
New media file broadcast strategy is deleted；If will be no identical with new media file broadcast strategy in playback of media files Policy List
Playback of media files strategy, then it is assumed that new media file broadcast strategy is newly-increased playback of media files strategy, it is necessary to will be new
Playback of media files strategy is added in playback of media files Policy List.
In a step 309, if current media file broadcast strategy list has been traveled through, if so, then in the step 310, sentencing
It is disconnected whether to have newly-increased playback of media files strategy；If so, then in step 311, renewal plays the media text in the information list of position
Part broadcast strategy.
As shown in table 3, there is a field SCHEDULEID in playback of media files Policy List, each media file is broadcast
Putting strategy has a unique SCHEDULEID, if a playback of media files strategy SCHEDULEID is in new media text
Exist in part broadcast strategy, be not present in current playback of media files strategy, then this is newly-increased playback of media files plan
Slightly；If playback of media files strategy SCHEDULEID is not present in new playback of media files strategy, in current media
Exist in file broadcast strategy, then this playback of media files strategy is expired playback of media files strategy；If media file
Broadcast strategy SCHEDULEID exists simultaneously in new playback of media files strategy and current playback of media files strategy, then
This playback of media files strategy does not update.
If in step 303, if set top box is not received by playback of media files strategy from front end system；Then in step
In 311, then the more new state that playback of media files strategy corresponding to the information of position is played described in the policy database is set
To update.
Because during the playback of media files strategy that set top box receiving front-end system is sent, if set top box is dashed forward
So power-off, or have other accidents, it is possible to the playback of media files plan for causing set top box not send front end system
Situation about slightly receiving completely.
If after front end system asks playback of media files strategy, front end system is returned as space-time to set top box, then protects
All information of the broadcasting position information are stayed, are then set to the more new status field in playback of media files Policy List more
Newly.
It is if in step 305, invalid if newly playing position information list；Then in step step 311, then by the strategy
The more new state that playback of media files strategy corresponding to the information of position is played described in database is arranged to update.
If in step 307, compare new media file broadcast strategy whether with current media file broadcast strategy list
In whether have same policy；If nothing, in step 312, it is believed that playback of media files strategy is without change.Then in step 313,
New media file broadcast strategy is deleted.
If in a step 309, if current media file broadcast strategy list has been traveled through, if it is not, then in step 306
In, travel through current media file broadcast strategy table.
If in the step 310, determine whether newly-increased playback of media files strategy；If nothing, in a step 314,
The newly-increased playback of media files strategy of playback of media files Policy List addition, newly-increased playback of media files plan is downloaded from front end system
Media file slightly.
In step 315, then playback of media files strategy corresponding to the information of position will be played described in the policy database
More new state be arranged to renewal and finish.
Renewal finishes only presentation medium file broadcast strategy and had added in policy data, but does not indicate that media file
Download and finished.
So after playback of media files Policy List with the addition of newly-increased playback of media files strategy, the newly-increased media text
Media file does not obtain also from front end system corresponding to part broadcast strategy, so set top box needs end system transmission media forward
File request, carry play position information in the request, front end system, will be with according to the solicited message that receives and broadcasting position information
Media file corresponding to the broadcasting position information received is sent to set top box.
Above-mentioned acquisition, parse playback of media files strategy and finally determine whether to broadcast from front end system downloads of media file
Put media file corresponding to strategy, can be completed when registration or after the completion of registration, set top box is idle
Period complete, the embodiment of the present invention was not limited the specific period for obtaining, parsing playback of media files strategy.
It is playback of media files process provided in an embodiment of the present invention referring to Fig. 4, the process can be realized by set top box.Should
Flow mainly comprises the following steps：
In step 400, the playback of media files request that application is sent is received, is included in the playback of media files request
The identification information of the application of position information and request progress playback of media files is played, the broadcasting position information is used to indicate media
The reproduction time section and channel of file.
In step 401, position information table is played according to the broadcasting position information and the identification information-enquiry of the application.
In step 402, whether channel ID is in white list；If not existing, in step 403, according to current time time
Go through playback of media files Policy Table.
Channel ID is judged whether in white list, is that the information of WHITELISTINGFO fields in table 2 determines.
Such as：The request of 1 satellite TV plays the media file of company A, the information of the WHITELISTINGFO fields in table 2, sentences first
Disconnected 1 satellite TV wherein have recorded the channel list that can not play media file whether in white list list in white list list, if
1 satellite TV is present in white list list, then it represents that 1 satellite TV can not play media file, and set top box can send a nothing to 1 satellite TV
Effect response.If 1 satellite TV is not present in white list list, then it represents that 1 satellite TV can play the media file of company A.
In step 404, judge whether it is correlated resources；If so, then in step 405, whether channel ID is in correlated resources
In information list；If in a step 406, according to priority or random selection media file.If so, in step 407
In, media file is present；If so, in step 408, renewal application plays position Registry.
Channel ID whether in correlated resources information list be according to CORRELATIVEFLAG fields in table 3 and
CORRELATIVECHENNELINFO fields determine.Such as：The request of 1 satellite TV plays the media file of company A, first, really
The whether relevant resource identification of fixed 1 satellite TV, in table 3, if CORRELATIVEFLAG fields are shown as 0, then it represents that 1 satellite TV is not
It is correlated resources；If CORRELATIVEFLAG fields are shown as 1, then it represents that 1 satellite TV is correlated resources.Wherein, correlated resources are
It is set in advance, such as, correlated resources are set as local satellite TV, then if 1 satellite TV is certain satellite TV of the Northwest, then 1 satellite TV
It is exactly correlated resources.Need further exist for judging 1 satellite TV whether in correlated resources information list, correlated resources information list can
With the local satellite TV including audience ratings top 10, either including East China satellite TV or including satellite TV of the Northwest etc..If
What correlated resources information list included is East China satellite TV, then can determine 1 satellite TV not in correlated resources information list
In, so 1 satellite TV can not play the media file of company A；If what correlated resources information list included is satellite TV of the Northwest,
1 satellite TV can so be determined in correlated resources information list, so 1 satellite TV can play the media file of company A.
Further, if broadcast mode regulation plays according to priority orders, according to the broadcasting position information pair
The priority for the media file answered, it is the application selection media file from media file corresponding to the broadcasting position information；
Or
It is described answer from media file corresponding to the broadcasting position information if the broadcast mode provides shuffle
With random selection media file.
There is a PLAYMOD field in table 3, if the field is shown 0, then it represents that the mode of playback of media files is
Played in order；If the field is shown 1, then it represents that the mode of playback of media files is shuffle.
For example the request of 1 satellite TV plays the media file of company A, wherein, the media file of company A can include A1 media
File, A2 media files, A3 media files or A4 media files etc..If PLAYMOD fields are shown 0 in table 3, from A
At will one media file of selection allows 1 satellite TV to play in the media file of company；If PLAYMOD fields are shown 1 in table 3,
Then need to play media file according to the order of priority.
There is an ADINDX field in table 4, the numerical value shown in the field is smaller, then it represents that corresponding media file
Priority is higher.For example the numerical value that A1 media files are shown is that the numerical value that 3, A2 media files are shown is that 5, A3 media files are shown
Numerical value be that the numerical value that 2, A4 media files are shown is 1, then it is A4 media that can determine that 1 satellite TV needs the media file that plays
File.
Further, can be from being all shown as 0 if the numerical value all 0 shown in ADINDX fields in table 4
It is application one media file of random selection in media file.
In step 409, judge whether playback of media files strategy needs to update；If desired, in step 413, in the past
End system downloads of media file broadcast strategy.
If in step 402, whether channel ID is in white list；If in step 415, terminating playing request
Process.
If it is correlated resources in step 404, to judge whether；If it is not, then in a step 406, according to priority or
Randomly choose media file.
If in step 405, whether channel ID is in correlated resources information list；If not existing, in step 403,
Playback of media files Policy Table is traveled through according to current time.
If in a step 406, according to priority or random selection media file；If it is not, then in step 414, time
End is gone through, selects default media file.If in step 407, media file is present；If nothing, in step 412, in the past
End system downloads of media file.
Wherein, media file whether there is what is mainly judged according to following method, such as, the request of 1 satellite TV plays company A
Media file, wherein, the ADINDX fields of the media file of company A in table 4 are shown, are respectively：A1 media files are shown
Numerical value be that the numerical value that 3, A2 files are shown is that the numerical value that 5, A3 media files are shown is that the numerical value that 2, A4 media files are shown is
1。
The media file that 1 satellite TV, which can be determined, to be needed to play is A4 media files, but because media file is machine top
For box forward after end system hair media file download request, front end system will be with playing position according to the broadcasting position information carried in request
Media file corresponding to information is sent to set top box, and set top box is when from front end system downloads of media file, may
It is de-energized suddenly.For example have multiple files in media file corresponding to the broadcasting position information of company A, it is possible that A1 can have been downloaded
Media file, A2 media files and A3 media files, A4 media files are not downloaded only and completed, set top box is just de-energized
.So, it is necessary to judge whether A4 media files are deposited after the media file for determining that 1 satellite TV needs play is A4 media files
.
