Embodiment
Below in conjunction with accompanying drawing and embodiment technical scheme of the present invention is done further detailed explanation.
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 following:
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 through its BOSS to providing to give in user's the smart card.Program products information is unique sign that this program is different from other programs, and this embodiment selects program products ID number for use as program products information.
Step 13: front end SI system (operating information system) adds the privately owned 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 privately owned descriptor, judge whether to search for and to show the sign of control to TV program list as receiving terminal.
Step 14: the BAT table that the receiving terminal receiving front-end sends, judge in the BAT table whether include privately owned 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 receiving terminals such as STB, digital intergrated unit receive TS stream, therefrom obtains the BAT table, judges the privately owned descriptor that whether includes regulation in the BAT table then.
Step 15: if do not contain privately owned descriptor in the BAT table, then normal display of television programmes tabulation.When also promptly in BAT table, not comprising privately owned descriptor, program is searched for, normally shown in the search procedure, add that the back also can show in the TV program list to when the user checks according to method of the prior art.
Step 16: if the privately owned descriptor of implication in the BAT table shows and will show control to the corresponding TV program list of this BAT table that 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 following:
Step 21: configuring high-frequency head essential information.Be included as information such as tuner configuration frequency, coincidence rate, modulation system.
Step 22: the message structure of initialization BAT table.Here be meant 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 privately owned descriptor that whether includes regulation in the BAT table that is received.If execution in step 25 is arranged; Otherwise, go to step 27.
Step 25:, then need show control to the corresponding the rendition list of this BAT table if include privately owned descriptor in the BAT table.At this moment, judge at first whether receiving terminal is inserted with smart card.If execution in step 26 is arranged; If no smart card then goes to step 27.
Step 26: when receiving terminal is inserted with smart card, from smart card, read the program products information in the card, be meant in this embodiment program products ID number.
Step 27: begin to search for program.
If do not comprise privately owned descriptor in the BAT table, do not show and need show control the corresponding the rendition list of this BAT table, 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 privately owned descriptor, the needs mandate.
Generally speaking, the user can show the corresponding program list information of BAT table in searching the process of platform, supply the user to know the program that the local reception terminal can search intuitively.And after searching the rendition list, need it be added in the receiving terminal memory, and on user's display interface, show, 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, it is following to the process that the rendition list adds to begin to search for program:
Step 31: begin to search for program 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 at interval.
Step 34: the BAT information searching and the corresponding BAT classified information of the rendition list of from the receiving terminal memory, being stored according to logical channel numbers.
Special, if the bouquet that comprises among the BAT is program prioritize services crowd, then need not 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 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 inequality with the program products information that reads from smart card; Explain that this BAT that is provided with program products information shows pairing the rendition list and need hide; Therefore; Search and hide the rendition list in the platform process, only this rendition list is added in the memory.At this moment, though the rendition list does not show that it Already in the memory of receiving terminal, can access at any time when needed, and needn't be to search for again 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; Relatively the time, also can obtain both different results of step 37 so, therefore, the BAT that correspondence is provided with program products information shows pairing the rendition list and also need hide.And, explain that the rendition list of this BAT table correspondence need not carried out hiding the processing if do not have program products information in the BAT table, so directly the display program tabulation gets final product in searching the platform process.
Step 39: if the program products information in the BAT table is identical with the program products information that reads from smart card; Explain that the program that is searched is for authorizing program; And smart card also is inserted into receiving terminal; Therefore, display program tabulation in searching the platform process, and add corresponding the rendition list in memory.
After the flow process through 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 can't see needs mandate just can watch when searching platform; Perhaps when inserting smart card, not can't see yet, can see the experience directly perceived 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, according to program prioritize services crowd the BAT table is sorted then, after having arranged preface, fill the rendition list content according to the Search Results of searching platform.This content filling process and prior art are similar, do not specifically describe at this.
Not only in searching the platform process, can show control to the rendition list that the need mandate just can be watched; And; In receiving terminal start or when getting into 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 that dynamic display of television programmes is tabulated among Fig. 1 embodiment.The tabulation of so-called dynamically display of television programmes be meant the TV program list that when receiving terminal is inserted with smart card, can view mandate, and after the smart card of receiving terminal was pulled out, the user can't see the TV program list that need license again.The dynamic procedure for displaying of realizing above-mentioned functions is following:
Step 41: receiving terminal display program tabulation.In this embodiment, receiving terminal is after start, and during perhaps through 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 execution in step 43 is arranged; If do not have, go 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 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:, then do not show the corresponding the rendition list of BAT table that has privately owned descriptor if the program products information in the BAT table is inequality with the program products information that reads from smart card.
Step 48:, then show and the corresponding the rendition list of program products information if the program products information in the BAT table is identical with the program products information that reads from smart card.
Above-mentioned flow process is judged through the plug state to smart card; Be inserted with smart card and smart card when having authorization message; Just, display program will authorize the rendition list that just can see to show when tabulating; And if do not exist when not having corresponding mandates in smart card or the smart card, the user can't see the rendition list that needs mandate just can see, has effectively avoided user's mistake to see and puzzle.
The foregoing description is taken all factors into consideration influences 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 intelligently filters and dynamic demonstration to TV program list has been proposed; Avoided showing chaotic, the use that reduces the user is puzzled, has improved the comfortableness that the user watches TV programme; Reduce user's complaint, more helped the popularization and the use of receiving terminal for digital television such as STB.
