Fig. 2 is the existing program broadcasting method schematic flow sheet based on NGOD based on Fig. 1.Referring to Fig. 2, this flow process comprises:
Step 201, ODC obtains the program playlist by the A7 interface from NS;
In this step, ODC obtains the program playlist request by sending to NS, obtains the program playlist from NS, for example, and electric program menu (EPG, Electronic Program Guide).
The program playlist can be the rendition list name, it also can be single program names, if the rendition list name, then program is concrete listing corresponding to this rendition list, if single program names, then the broadcast program program is the listing that advertisement insertion is arranged, and namely must finish first advertisement could broadcast program.
Step 202, ODC orders the program for the treatment of program request by the E2 interface from PS, generates to order the program playlist;
In this step, ODC chooses one or more programs for the treatment of program request according to the program playlist that obtains from NS, orders to PS, thereby realizes the paying program request.
Step 203, ODC sends the tabulation authentication request by the S1 interface to SM, carries and orders the program playlist;
In this step, ODC is buying behind the program of program request to PS, plays this to the SM request and orders the program playlist.
In the practical application; after the user orders program by ODC; after receiving order program playlist; because can the operations such as the program of ordering in the program playlist adds, deletion to ordering; in order to protect the legitimate rights and interests of operation manufacturer, need to carry out authentication to the order program playlist that the user submits to.
Step 204, SM is undertaken alternately by S2 interface and PS, and the order program playlist of asking is carried out authentication, generates authentication program playlist;
In this step, SM receives the tabulation authentication request that ODC sends, and carries out alternately with PS, and PS is according to user's ordering information of storage, and to the program of respectively treating program request of user by this ODC transmission, for example, program 1 carries out authentication to program n.
In the embodiment of the invention, the order program of request is generally the program that ODC buys, for example, and the rendition list name or single program names.
Step 205, SM returns to ODC by the S1 interface with authentication program playlist;
In this step, the program that comprises in the order program playlist after the authentication (authentication program playlist) is the partial programme that comprises in the order program playlist that carries when SM asks of ODC or whole programs.Be that PS deletes the unsanctioned program of authentication from the order program playlist that receives, form at last authentication program playlist.
Step 206, ODC is by the S1 interface, the program i in the SM request authentication program playlist;
In this step, ODC sequentially plays corresponding program to the SM request according to the authentication program playlist that receives.For example, for initial play, i=1 then, namely the top line from authentication program playlist begins, and request is play.
Step 207, SM carries out alternately with PS by the S2 interface, and the program i that receives is carried out authentication;
In this step, as previously mentioned, because the user can change ordering the program playlist by ODC, also can change authentication program playlist, thereby SM need to carry out independent authentication to each program that ODC sends.
After the authentication of the program i of user's program request is passed through, carry out subsequent step.
Step 208, SM is by the S3 interface, from ODRM request program i;
In this step, SM asks this program i to ODRM after the authentication of program i is passed through.
Step 209, ODRM obtains the positional information of SS by the R1 interface from APM;
In this step, ODRM sends the location information request of obtaining SS by the R1 interface to APM, and APM is by the A3 interface, and is mutual with SS, obtains the positional information of SS and is back to ODRM by the R1 interface.
Step 210, ODRM obtains the plug-flow port information of SS by Interface R2;
In this step, ODRM obtains the plug-flow port information of SS according to the positional information of the SS that obtains by Interface R2.
Step 211, ODRM is by the S3 interface, and positional information, the plug-flow port information of SS returned to SM;
Step 212, SM is by the S1 interface, and positional information, the plug-flow port information of SS returned to ODC;
Step 213, ODC sends the beginning play instruction of program i according to the information that receives to SS by the C1 interface;
In this step, SM returns to ODC by the S1 interface with positional information, the plug-flow port information of SS, when ODC begins broadcast program, according to positional information and the plug-flow port information of SS, send the beginning play instruction to SS, this begins play instruction for the program i in the authentication program playlist.
After SS receives the beginning play instruction, the program i of beginning play-on-demand.
Step 214, program i plug-flow is complete, and SS is by the C1 interface, and notice ODC program i plug-flow finishes;
In this step, SS notifies ODC behind the complete program i of plug-flow, and plug-flow is complete for the program i in the authentication program playlist.Be that SS plug-flow program i finishes, perhaps plug-flow finishes, but video request program does not finish, and needs ODC to determine whether to finish the video request program of this program i by the C1 interface.
Step 215, ODC receives the plug-flow ending message, sends to SS by the C1 interface and finishes program i instruction;
In this step, ODC determines that the broadcast of current program i finishes after receiving the plug-flow ending message, send the instruction that finishes program i to SS.
Step 216, SS returns to ODRM by Interface R2 with the end program i instruction that receives;
In this step, the end play instruction that SS will finish the program i in the authentication program playlist returns to ODRM.
Step 217, ODC sends to SM by the S1 interface and finishes program i instruction;
This step does not have dividing of sequencing with step 215, can carry out before step 215, can carry out simultaneously with step 215 yet, and the end program i instruction of transmission is for the program i in the program playlist.Thereby finish SM to the Play Control of program i.
Step 218, ODC determines to play next program, by the program (i+1) of S 1 interface from SM request authentication playlist.
In this step, ODC circulation execution in step 206 is to step 217, until the whole programs in the authentication program playlist (program 1 is to program n) are finished playing.
By as seen above-mentioned, existing program broadcasting method based on NGOD, ODC is by sending playing request to SM, obtain the program playlist from SM, then, ODC sends order request to SM successively, program in the program request authentication playlist, SM is for order request each time, all need to carry out authentication, after the program of each program request finishes playing, need this program of SS notice ODC to play and finish, thereby so that ODC can begin the next program in the program request authentication program playlist, thereby realize the sequentially broadcast of each request program.Like this, because ODC has obtained first the program of authentication program playlist, and then plays, so that ODC can increase or delete the program in the authentication program playlist, what cause that program in the authentication program playlist plays is imperfect, and the fail safe that program is play is lower; Further, ODC whenever carries out a program request, just need to carry out one time authentication, for the situation that comprises a plurality of programs in the authentication program playlist, authentication has increased the authentication interaction times between PS and the SM often, and because playing, the program in the authentication program playlist all needs successively order program request of ODC, also increased the order request interaction times between ODC and the SM, so that required time is play in request program is longer, the playing flow of authentication program playlist is comparatively complicated; And because the program that finishes playing at every turn, SS needs to notify ODC to play end, has increased the program request notice number of times between SS and the ODC, has also increased the required resource overhead of video playback; In addition, rely on the broadcast that ODC finishes authentication program playlist, caused the complexity of the ODC access NGOD system platform of different vendor, increased the mutual of ODC and NGOD system platform, also have hidden danger for the fail safe of authentication program playlist.
