Please refer to Fig. 1, this Fig. 1 illustrates the overview flow chart of an embodiment of display packing of TV program list of the present invention.
As shown in Figure 1, this embodiment realizes that the process of TV program list demonstration is as follows:
Step 11: flow process begins.
Step 12: front end CA system (condition receiving system) writes program products information in smart card.
Broadcasting and TV front end CA system at first writes program products information by its BOSS in the smart card of providing to the user.Program products information is unique sign that this program is different from other programs, and this embodiment selects program products ID number as program products information.
Step 13: front end SI system (operating information system) adds the private setting descriptor of program products information and setting in BAT table (BAT bouquet association table).
Watch for ease of judging according to smart card whether the user of TV programme is authorized user, front end SI system adds the program products information identical with smart card in the BAT table.And, require the SI system to be supported in and add the User Defined description among the BAT, and in User Defined is described, add private setting descriptor, judge whether to search for and to show TV program list the sign of control as receiving terminal.
Step 14: the BAT table that the receiving terminal receiving front-end sends, judge in the BAT table whether include private setting descriptor.If, execution in step 16; If not, execution in step 15.
The BAT table that front end sends is added in the TS stream, and the receiving terminals such as set-top box, digital intergrated unit receive TS stream, therefrom obtains the BAT table, then judges the private setting descriptor that whether includes regulation in the BAT table.
Step 15: if do not contain private setting descriptor in the BAT table, then normal display of television programmes tabulation.When also namely in BAT table, not comprising private setting descriptor, according to method of the prior art program is searched for, normally shown in the search procedure, when the user checks, also can show after adding in the TV program list.
Step 16: if implication private setting descriptor in the BAT table shows that show corresponding TV program list to this BAT show control, then plug state and the program products information in the smart card according to smart card determines whether display of television programmes is tabulated.
The concrete demonstration control procedure of this step and method can be with reference to figure 2, Fig. 3, Fig. 4 and following descriptions to these accompanying drawings.
Please refer to Fig. 2, this Fig. 2 shows the flow chart of receiving terminal searching TV program among Fig. 1 embodiment.As shown in Figure 2, the idiographic flow of searching TV program is as follows:
Step 21: configuring high-frequency head essential information.Be included as the information such as tuner configuration frequency, coincidence rate, modulation system.
Step 22: the message structure of initialization BAT table.Here refer to the initialization of the BAT list structure body that will store in the initialization receiving terminal memory.After the initialization, be used for preserving the BAT table information of extracting from TS stream.
Step 23: receive TS stream, obtain BAT table and filtration.
Extract the BAT table in the SI information of receiving terminal from TS stream, obtain self-defined description part in the BAT table.
Step 24: judge the private setting descriptor that whether includes regulation in the BAT table that receives.If have, execution in step 25; Otherwise, go to step 27.
Step 25: if include private setting descriptor in the BAT table, then need the rendition list corresponding to this BAT table shown control.At this moment, judge at first whether receiving terminal is inserted with smart card.If have, execution in step 26; If without smart card, then go to step 27.
Step 26: when receiving terminal is inserted with smart card, from smart card, read the program products information in the card, refer in this embodiment program products ID number.
Step 27: beginning searching programs.
If do not comprise private setting descriptor in the BAT table, showing does not need the rendition list corresponding to this BAT table shown control, can directly show.Perhaps, if receiving terminal is not inserted with smart card, so, directly hide for including the rendition list that could supply the user to check after private setting descriptor, the needs mandate.
Generally speaking, the user can show program list information corresponding to BAT table in the process of tuning, know intuitively the program that the local reception terminal can search for the user.And after searching the rendition list, it need to be added in the receiving terminal memory, and show at user's display interface, so that the user checks corresponding programme content according to the rendition list.Fig. 3 shows the flow chart that adds the rendition list among Fig. 1 embodiment.As shown in Figure 3, the beginning searching programs is as follows to the process that the rendition list adds:
Step 31: beginning searching programs list information.
Step 32: judge whether to exist the BAT table.If there is execution in step 33; Otherwise, go to step 31, continue search.
Step 33: when having the BAT table, obtain the logical channel numbers in the BAT table.
Logical channel numbers is to describe a serial number of the front and back ordinal relation between the channel, and this is a relative value, only is used for representing the front and back order of channel, is not absolute channel number.Front end can suitably be reserved certain intervals when filling in this logical channel numbers, with convenient follow-up interpolation and modification; And receiving terminal will rearrange and ordering according to this logical channel numbers, no longer leaves the interval.
Step 34: the BAT information searching BAT classified information corresponding with the rendition list of from the receiving terminal memory, storing according to logical channel numbers.
Special, if the bouquet that comprises among the BAT is program prioritize services group, then do not need to search the BAT classified information of this BAT table.
Step 35: obtain the program products information in the BAT table.
Step 36: the program products information that relatively reads on the program products information in the BAT table and the smart card.
Step 37: judging program products information and the program products information that reads from smart card in the BAT table, whether the two identical.If identical, execution in step 39; If different, execution in step 38.
Step 38: if the program products information in the BAT table is not identical with the program products information that reads from smart card, illustrate that this BAT that is provided with program products information shows corresponding the rendition list and need to hide, therefore, hide the rendition list in the tuning process, only this rendition list is added in the memory.At this moment, although the rendition list do not show, it Already in the memory of receiving terminal, can access at any time when needed, and needn't be to re-start search at needs.
Certainly, as a special case, if receiving terminal does not insert smart card, can not from smart card, get access to program products information, also can obtain both different results of step 37 so relatively the time, therefore, the BAT that correspondence is provided with program products information shows corresponding the rendition list also to be needed to hide.And if there is not program products information in BAT in showing, illustrate that the rendition list corresponding to this BAT table do not need to carry out hiding the processing, so direct display program tabulation gets final product in the tuning process.
Step 39: if the program products information in the BAT table is identical with the program products information that reads from smart card, illustrate that the program that searches is for authorizing program, and smart card also is inserted into receiving terminal, therefore, display program tabulation in the tuning process, and add corresponding the rendition list in memory.
After the flow process by above-mentioned Fig. 2 and Fig. 3, can control the demonstration in the rendition list search procedure according to the plug state of the smart card in the receiving terminal and the authorization conditions of smart card, guarantee the rendition list that unauthorized user be can't see needs mandate just can watch when tuning, perhaps when inserting smart card, not can't see yet, can see the intuitional and experiential thinking of programme content to see the rendition list for the user.
In addition, after searching the rendition list, also to carry out the process that the rendition list content is filled.In simple terms, after the BAT classified information of having searched all BAT tables, at first fill the BAT classified information exactly, then according to program prioritize services group the BAT table is sorted, after drained order, fill the rendition list content according to the Search Results of tuning.This content filling process and prior art are similar, are not described specifically at this.
Not only in the tuning process, can show control to the rendition list that the need mandate just can be watched, and, when receiving terminal is started shooting or is entered main interface display the rendition list, also can control the demonstration of the rendition list, detailed process and method can be with reference to shown in Figure 4.
As shown in Figure 4, the figure shows the flow chart of dynamic display of television programmes tabulation among Fig. 1 embodiment.So-called dynamically display of television programmes is tabulated, and refer to can view the TV program list of mandate when receiving terminal is inserted with smart card, and after the smart card of receiving terminal was pulled out, the user can't see again the TV program list that need license.The dynamic procedure for displaying of realizing above-mentioned functions is as follows:
Step 41: receiving terminal display program tabulation.In this embodiment, receiving terminal is after start, and during perhaps by main interface display the rendition list, the trigger action of all tabulating as display program is to guarantee the accurate demonstration of the rendition list as far as possible.
Step 42: judge whether receiving terminal is inserted with smart card.If have, execution in step 43; If nothing goes to step 47.
Step 43: when receiving terminal is inserted with smart card, read program products information from smart card.
Step 44: read the program products information in the BAT table.
Step 45: the program products information that relatively reads on the program products information in the BAT table and the smart card.
Step 46: judging program products information and the program products information that reads from smart card in the BAT table, whether the two identical.If identical, execution in step 48; If different, execution in step 47.
Step 47: if the program products information in the BAT table is not identical with the program products information that reads from smart card, then do not show the rendition list corresponding to BAT table with private setting descriptor.
Step 48: if the program products information in the BAT table is identical with the program products information that reads from smart card, then show the rendition list corresponding with program products information.
Above-mentioned flow process is judged by the plug state to smart card, when being inserted with smart card and smart card and having authorization message, just when tabulating, display program will authorize the rendition list that just can see to show, if and do not exist when not having corresponding mandate in smart card or the smart card, the user can't see and need to authorize the rendition list that just can see, has effectively avoided user's mistake to see and puzzle.
Above-described embodiment considers affects the CA of program classification, ordering and demonstration system, front-end server and receiving terminal, a kind of TV program list display packing that can carry out to TV program list intelligently filters and dynamic demonstration has been proposed, avoided showing chaotic, the use that reduces the user is puzzled, improved the comfortableness that the user watches TV programme, reduce user's complaint, more be conducive to popularization and the use of the receiving terminal for digital television such as set-top box.
