Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the following embodiments and accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
Implementation mode one
The invention provides a program ordering method of a conditional access system, which comprises the following steps: the terminal judges whether the terminal user orders the charging program according to the ordering information displayed by the terminal; if the judgment result is yes, the terminal deducts the charge of the charged program from the corresponding wallet; wherein the pay program is an internet protocol private program (IPPT) program, and the subscription information at least includes a program Identifier (ID), a wallet Identifier (ID) for payment, and a viewing time.
According to the embodiment, the terminal user orders the IPPT program according to the IPPT program ordering information displayed by the terminal by the method, and the IPPT program can be watched by deducting the cost of the IPPT program from the corresponding wallet without informing an operator to authorize, so that the time is saved and the user can conveniently purchase the charged program.
In this embodiment, after the terminal user orders the IPPT program according to the ordering information displayed by the terminal and deducts the corresponding fee, the terminal can play the IPPT program for the terminal user to watch. Then, the method may further include:
the terminal judges whether the IPPT program is expired; if the judgment result is yes, the terminal judges whether the IPPT program is ordered by adopting a manual ordering mode or an automatic ordering mode; and if the judgment result is that a manual ordering mode is adopted, displaying the ordering information. In this way, the end user may again order the premium programming based on the subscription information displayed by the terminal. And if the automatic ordering mode is adopted, the terminal automatically deducts the charge of the charged program from the corresponding wallet.
In this embodiment, after the end user orders the premium program, the method further includes: the terminal stores subscription information and payment information of the premium program. The above information may be stored in a security device of the terminal. Therefore, the user and the operator can conveniently inquire through the terminal.
In this embodiment, the order information may include information of the operator, expiration time, and the like, in addition to a program Identifier (ID) and a paid wallet Identifier (ID), viewing time, and prices for recording and non-recording.
In this embodiment, the following method can be adopted to determine whether the end user subscribes to the premium program according to the subscription information: receiving an instruction input by the terminal user, wherein the terminal user can input the instruction through a remote controller key; judging whether the command is a command for ordering the charging program; and if so, determining that the terminal user subscribes the charging program.
In this embodiment, before the terminal determines whether the terminal user orders the premium program, the method further includes: the terminal receives a data packet sent by the front end, wherein the data packet at least comprises charging program information and the current time for issuing the data packet; the premium program information includes the subscription information; the data packet is processed to obtain subscription information for the premium programming. In this way, by displaying the subscription information on the terminal display interface, the terminal user can subscribe to the IPPT program according to the displayed subscription information.
In this embodiment, the IPPT program and the related information are provided at the head end. In this way, before the terminal receives the data packet transmitted by the front end, the method further includes: the front end configures the charging program and the charging program information in a program list file; extracting the charging program information and generating a data packet; the front end sends the data packet to the terminal.
In the above embodiment, the viewing time is preset by the front end, and after the IPPT program is first ordered, the terminal user can play the IPPT program through the terminal. The IPPT program may also be re-ordered after it has expired.
In this embodiment, the following method may be adopted to determine whether the IPPT program is expired:
calculating the time sum of the time of ordering the IPPT program and the viewing time; judging whether the time sum is greater than or equal to the current time; if the judgment result is yes, determining that the IPPT program is overdue. This is merely an embodiment of the present invention, and other ways to determine whether the IPPT program is expired may be used.
In this embodiment, the IPPT program may be re-ordered manually or automatically after the IPPT program has expired. Wherein, the terminal can judge whether to order the IPPT program in a manual mode or an automatic mode according to the wallet identification ID in the ordering information. But is not limited to this and other means may be employed.
For example, in the present embodiment, the wallet is identified as 1, 2, 3, 4, and when the wallet identified as 1, 2, 3 is used for payment, the ordering mode is manual; when paying with a wallet with wallet id 4, the subscription mode is automatic. Thus, the above mode is preset and stored at the terminal, when the terminal judges that the subscribed IPPT program is out of date, the wallet mark of the IPPT program in the subscription information can be compared with the wallet mark of the preset subscription mode, and if the wallet mark of the IPPT program is any one of 1 to 3, the terminal can determine to manually subscribe the IPPT program again. If the wallet id of the IPPT program is 4, the terminal may determine to reorder the IPPT program in an automatic manner.
When the manual mode is adopted, the terminal can display the ordering information on the terminal display interface again, and the terminal user orders according to the displayed ordering information, which is similar to the mode of first ordering and is not repeated here. The automatic mode is that after the first order is carried out and the watching time is expired, the terminal does not prompt the order information any more, and the money is directly deducted from the appointed wallet according to the wallet identification ID of the IPPT, so that the terminal user can continuously watch the program without carrying out the order operation.
The following describes the subscription method of the present invention in detail by taking the example of setting IPPT programs and related information at the head end. The following description will be made by taking an example in which IPPT programs are manually ordered when the wallet id is 1 to 3, and IPPT programs are automatically ordered when the wallet id is 4.
As shown in fig. 6, the method includes:
For example, the following is an example of configuring IPPT program information in a program Listing File (XML):
< Service ID ═ 1 "Name ═ one center channel >
<PrimaryEvent>
<Product ID＝″1″/>
<IPPT ID＝″1001″/>
</PrimaryEvent>
</Service>
<IPPTDescsList>
<IPPT ID＝″1001″SlotID＝″4″Duration＝″00:20:00″Price＝″10″TapingPrice＝″20″
Name ═ IPPT product 1 ″/>
<IPPT ID＝″1003″SlotID＝″1″Duration＝″02:30:00″Price＝″20″TapingPrice＝″30″
Name ═ IPPT product 2 ″/>
</IPPTDescs>
Wherein:
1) primary Event: the primary event under the Service where it is located includes a common product 1 and an IPPT product 1001 in the above example, and one PrimaryEvent includes an IPPT program.
2) IPPTDescsList: is a list of all IPPT program descriptions including each IPPT program ID, viewing time (hh: mm: ss), wallet ID used, common price, and price with video recording capability. The above example contains 2 IPPT products 1001 and 1003. SlotID is wallet ID, Duration is viewing time, Price is the general Price without video recording function, and TapingPrice is the Price with video recording function.
3) The above program list configuration contains two IPPT programs: the IPPT1001 wallet is marked as 4, so that the IPPT1001 is an IPPT program automatically ordered, the viewing time is 20 minutes, the user can only order the program by using the wallet 4, the common price is 20, and the price for purchasing the video is 30; the IPPT1003 wallet mark is 1, so the IPPT1003 is an IPPT program ordered manually, the viewing time is 2 hours and 30 minutes, the user can only use wallet 1 to order, the common price is 10, and the price for purchasing the video is 20. However, the above configured "one central program" is configured using only the IPPT 1001.
In step 602, a data packet generating unit at the front end, in this embodiment, an ECMG, may obtain the charging program information from the stored program list file according to the pre-configured charging program information, print an ECM data packet, and send the ECM packet to the terminal.
In this embodiment, an ECM packet is transmitted by the IPPT program configured for each channel, and the front end issues the ECM packet at regular intervals, for example, the regular interval is 10 seconds. The ECM packet may include subscription information such as IPPT program ID, viewing time, wallet ID, general price, and price with video recording function. In addition, the current time of issuing the ECM data packet can be included. The format of the ECM packet of the charging program is shown in table 1:
TABLE 1
| Grammar for grammar | Note |
| IPPT_Data(){ | |
| IPPT ID | IPPT product identification ID |
| Duration | Viewing time |
| SlotID | Wallet identification ID |
| Price | Common price |
| TapingPrice | Price with video recording function |
| TimeStamp | Current time issued by front end |
| } |
In addition, the program scrambling and scheduling control information is used for ensuring the safety by calling an encryption machine through the ECMG, wherein the program scrambling and scheduling control are similar to the prior related technology and are not described again here.
In addition, after the terminal processes the ECM data packet, the current time for issuing the ECM data packet can be acquired, and the current time of the terminal is updated according to the issued current time. The updated current time for the terminal is 8:10: 30.
In the present embodiment, a purchase prompt box is displayed on a display unit of a terminal, and order information displayed in the prompt box includes, as shown in fig. 7: whether to purchase the program; operator information, such as operator ID and operator name; IPPT program ID; a wallet ID; ordering the prices of video and non-video; a toll collection unit, etc. Wherein, the operator ID is 3, and the operator is 3; IPPT program ID is 1001, wallet ID is 4, and viewing time is 20 minutes.
In this embodiment, in order to facilitate the terminal user to order the IPPT program using the remote controller, when the order information is displayed on the display unit, the terminal adds the corresponding buttons of the remote controller for ordering and not ordering the program, such as pressing [ blue key ] for ordering the program, pressing [ green key ] for ordering the recording, and pressing off-key for not ordering. Thus, the key information is also stored in the terminal, and when the order information is displayed, the key information can be displayed on the terminal display unit at the same time. The key information can be stored in the terminal security device.
And step 604, the terminal judges whether the terminal user orders the IPPT program, if the terminal user orders the IPPT program, the terminal user operates the IPPT prompt box through a remote controller, and selects to purchase, record or not to record according to the displayed ordering information and the added corresponding key information, and the selected price is different. In this embodiment, if the end user presses the blue key or the green key of the remote controller, the terminal determines that the end user has subscribed to the IPPT program. In this embodiment, the end user may not view the IPPT program until the program is purchased.
Thus, the terminal deducts the cost of the IPPT program from the terminal security device's wallet 1 according to the terminal user's selection, so that the terminal user can watch the IPPT program.
In steps 605 and 606, if it is determined that the end user subscribes to the IPPT program in step 604, the cost of the IPPT program is deducted from the corresponding wallet of the secure device, that is, wallet 4. After deducting the cost of the IPPT program, the terminal can play the IPPT program for the terminal user to watch.
calculating the time sum of the time of ordering the IPPT program and the viewing time; judging whether the time sum is greater than or equal to the current time; if the judgment result is yes, determining that the IPPT program is overdue. For example, the time when the terminal subscribes to the IPPT program is 8:10:30, and the viewing time of the IPPT program is 20 minutes, so that the sum of the time when the terminal subscribes to the IPPT program and the viewing time is 8:30:30, and when the sum of the times reaches the current time of the terminal, the IPPT program is determined to be expired. The current time of the terminal is determined by the delivery time of the delivered ECM data packet.
If the determination result is not expired, proceed to step 606.
In addition, if the wallet id of the IPPT program is set to 1 when the setting is performed at the front end, it may be determined that the IPPT program is ordered manually in step 608. Thus, the terminal displays the obtained ordering information of the IPPT program on the terminal display unit (see step 610), at this time, the terminal user can order the IPPT program according to the displayed ordering information, the operation process is similar to the first order, and details are not repeated here.
There may be multiple wallets in the terminal security device, such as: different program suppliers use different purses, and the amount of programs sold by different program suppliers can be counted during counting, so that operators can uniformly manage all users. And the terminal user pays the fee to the appointed wallet in the payment process. The safety device records the number of points corresponding to the money or the recharged money, such as the total number of points and the consumed number of points.
The terminal user can inquire the information of each wallet through the display unit of the terminal, including the amount of money charged by each wallet and the amount of money spent; if the amount of money in the wallet is insufficient, the terminal user cannot watch the IPPT program, and thus, the display unit of the terminal can display corresponding prompt information.
According to the embodiment, the terminal user orders the IPPT program according to the IPPT program ordering information displayed by the terminal by the method, and the IPPT program can be watched by deducting the cost of the IPPT program from the corresponding wallet without informing an operator to authorize, so that the time is saved and the user can conveniently purchase the charged program. And when the IPPT program is purchased again, the subscription can be made manually or automatically according to the preset setting selection. And the ordering information and the payment information can be stored, so that the user can conveniently inquire and the operator can conveniently manage the payment information in a unified way.
