The present invention provides a kind of playback method of TV programme.
Referring to Fig.1, Fig. 1 is the flow diagram of the playback method first embodiment of TV programme of the present invention.
The present embodiment proposes that a kind of playback method of TV programme, the playback method of the TV programme include:
It is corresponding to obtain the program to be broadcast that server is sent in the play instruction for detecting program to be broadcast by step S10 Transport stream, and obtain the close card of specified view of the program to be broadcast and identify；
In the present embodiment, before the step S10, include the steps that server editor's transport stream, the server is compiled The mode for collecting transport stream includes: the transport stream of 1, extraction program to be broadcast, by preset edit tool, in the transport stream of extraction That is TS flows in corresponding information table, and description field is written as needed.Wherein, the key parameter of description field includes: cam_ Protection_mode, indicates whether the program needs specified CAM manufacturer；Number_of_cam indicates CAM specified number； Cam_brand_identifier indicates that specified CAM brand ID regards close card mark, it is notable that a program It can specify multiple CAM and broadcasting be decrypted, that is to say, that, can be in the corresponding presupposed information table of the transport stream of a program The close card mark of multiple views is written, to authorize to multiple depending on close card.2, the transport stream in server, equally, root are directly acquired It according to preset edit tool, is flowed in corresponding information table in transport stream, that is, TS of acquisition, is written description field as needed, and institute It states in presupposed information table, to add each description field at this time for each program, it will be understood that transport stream is transmitted directly to electricity Depending on terminal, subsequent television terminal is decrypted the transport stream of corresponding portion according to program to be broadcast, that is to say, that clothes Business device uniformly sends transport stream, rather than transmits corresponding transport stream for different programs to be broadcast, to reduce server Processing pressure.
In the present embodiment, the play instruction of the program to be broadcast can be based on touch operation by remote terminal and touch Hair can also be based on touch operation by television terminal and operate and trigger.In the play instruction for detecting program to be broadcast, first know The corresponding service id of not described program to be broadcast (i.e. service ID), due to having always on the transmission line of television terminal connection TS stream, therefore, when needing to switch specific program or broadcast interface, identifies the service ID of the program to be broadcast, according to described ID is serviced, PSI/SI (Program Specific Information) information (the i.e. PAT (Program Association Table), PMT (program map obtained from TS stream Table) etc. tables) position (PID) in TS stream that determines corresponding program, broadcasting is then decrypted.It is understood that described Transport stream is encrypted by scrambled control word (Control Word, hereinafter referred to as CW).
Step S20 specified regards close card mark with corresponding prestore depending on close card that television terminal install depending on close card mark for described Knowledge is compared；
Step S30, it is described it is specified depending on close card mark with it is described prestore regard close card identify match when, by it is described transmit spread It transports in the close card of view, and based on the transmission stream broadcasting program after the close card decryption of the view.
In the present embodiment, in the mode difference for the close card mark of specified view for obtaining the program to be broadcast, including it is following Two kinds of embodiments:
1) mode one, the close card of specified view for obtaining the program to be broadcast identify the following steps are included:
Judge the television terminal currently and whether there is the prestored information table of the program to be broadcast；
If there is currently no the prestored information tables of the program to be broadcast, it is determined that can be described in prefixed time interval The corresponding information table of the program to be broadcast is got in transport stream；
If the corresponding information table of the program to be broadcast is got in the transport stream in prefixed time interval, in institute State the close card mark of specified view that the program to be broadcast is obtained in the corresponding information table of program to be broadcast；
It, will if obtaining information table corresponding less than the program to be broadcast in prefixed time interval in the transport stream The transmission is streamed in the close card of view, and based on the transmission stream broadcasting program after the close card decryption of the view.
In the present embodiment, get server transmission transport stream after, television terminal first judge currently whether There are the prestored information tables of the program to be broadcast, specifically can be according to the service id and name of the program to be broadcast in number According to matching in library, to determine whether or not there have been the corresponding prestored information table of the program to be broadcast, the prestored information table includes SDT (Service description section, service data table), NIT (Network Information Table, net Network information table) or several information tables such as PMT (Program Map Table, Program Map Table), further, for TV Festival Purpose playing efficiency, the prestored information table is preferably SDT table, and specific reason is as follows: if being needed using other tables such as NIT table NIT prototype structure is modified, specific program information is increased, repeats, results in waste of resources with SDT table partial content；If using PMT Table, then each zapping requires to update parsing PMT, extracts cam_protection_mode description field, increases system burden. And SDT table contains all programme informations, convenient for increasing cam_protection_mode description field to specific program.Therefore, In this embodiment, using SDT table, then after the completion of tuning, all programs can disposably be parsed by obtaining SDT table Cam_protection_mode description field, and be stored in database, the efficiency for accelerating TV programme selection and playing, Improve running efficiency of system.And in the prestored information table of the program to be broadcast, it may include the close card mark of view specified in advance, It indicates that the program to be broadcast just has play right depending on close card for certain, can not also include regarding close card mark, indicate all Depending on close card can the transport stream broadcasting program is decrypted.
In the present embodiment, if there is currently no the prestored information tables of the program to be broadcast, at this point, first forbidding to pass It is defeated to be streamed to the close card of view, but timing is started by preset timer, it can be described in prefixed time interval to determine The corresponding information table of the program to be broadcast is got in transport stream, the prefixed time interval is set as the case may be It sets, is such as set as 5 seconds, if getting the corresponding information of the program to be broadcast in the transport stream in prefixed time interval Table, analyzes the parameter information in the corresponding information table of the program to be broadcast, and the parameter information, that is, program to be broadcast Description field such as cam_protection_mode, number_of_cam and cam_brand_ in corresponding information table Identifier etc., the close card of specified view for determining whether there is the program to be broadcast according to these parameter informations identify, i.e., In parameter information whether there is cam_protection_mode information field, and if it exists, illustrate server send transport stream it Before, the close card of view that the program to be broadcast specifies authorization is identified, then, at this point, obtaining the program to be broadcast The specified close card mark of view, and by the specified close card of view identify with the television terminal install depending on close card it is corresponding prestore regard it is close Card mark be compared, and it is described it is specified view close card identify with it is described prestore depending on close card identify match when, by the transport stream It is transmitted in the close card of view, and based on the transmission stream broadcasting program after the close card decryption of the view；It is understood that described It is specified regard close card mark with it is described prestore the close card of view and identify mismatch when, forbid to transmit being streamed to regarding in close card, at this point, institute State television terminal installation is the equal of the close card of view of server unauthorized depending on close card, and television terminal, which is forbidden to transmit, to be streamed to In the close card of view of the television terminal installation, i.e., the transport stream of the program to be broadcast can not be solved depending on close card by described It is close, cause the program to be broadcast that can not play.
Further, if the corresponding letter of the program to be broadcast can be got in prefixed time interval in the transport stream Table is ceased, and when including multiple programs in the information table, can first extract the close card of the corresponding specified view of each program and identify, it can will be each A program it is corresponding it is described it is specified depending on close card mark with it is described prestore to regard close card and identify be compared, to obtain in each program and It is described to prestore the matched specified close card mark of view of the close card mark of view, it is finally identified, that is, can determine according to the close card of the specified view of acquisition Then program to be broadcast extracts the partial transport streams of the program to be broadcast in the transport stream, subsequent after successful decryption, It can be according to the transmission stream broadcasting program after decryption.If not got in institute's transport stream in prefixed time interval described wait broadcast The corresponding information table of program is put, can indicate that the transport stream of server transport is not limit the close card mark of view, that is to say, that only Transmission can be streamed to depending on being decrypted in close card by the television terminal being equipped with depending on close card, be based ultimately upon the close card of view Transmission stream broadcasting program after decryption.
2) mode two, the judgement television terminal in mode one currently whether there is the program to be broadcast After the step of prestored information table, the step of close card of specified view for obtaining the program to be broadcast identifies further include:
If there is currently the prestored information tables of the program to be broadcast, it is determined that whether prestored in the prestored information table The close card mark of the specified view of the program to be broadcast；
When prestoring the specified view close card mark of the program to be broadcast in the prestored information table, letter is prestored from described The close card mark of specified view of the program to be broadcast is obtained in breath table.
In the present embodiment, if not spending parsing at this time there is currently the prestored information table of the program to be broadcast It whether there is information table in transport stream, determine whether prestore in the prestored information table directly in the prestored information table State the close card mark of specified view of program to be broadcast, that is to say, that whether check in the prestored information table comprising cam_ Protection_mode information field, and if it exists, illustrate to prestore the specified of the program to be broadcast in the prestored information table It is identified depending on close card, the close card mark of specified view of the program to be broadcast is obtained in the prestored information table, and prestored described The close card mark cam_brand_identifier such as cam_brand_3 of specified view in information table and the view that television terminal is installed are close Block it is corresponding prestore depending on close card mark as cam_brand_3 is compared, identified in the close card of the specified view and described prestore view When close card mark matching, the transmission is streamed in the close card of view, and based on the transport stream after the close card decryption of the view Play program.
In the present embodiment, in television terminal, there is currently the prestored information tables of the program to be broadcast, first determine institute The close card mark of specified view that the program to be broadcast whether is prestored in prestored information table stated, and if it exists, again by the specified view Close card mark is compared with corresponding prestore depending on close card that television terminal is installed depending on close card mark, finally close in the specified view Card mark with it is described prestore regard close card mark match when, be directly based upon it is described regard it is close block decrypt after transmission stream broadcasting program, in fact Show before determining whether program to be broadcast can play, has been first from the limit for determining program to be broadcast in system in prestored information table The close card mark of the view of system, and do not have to obtain in the transport stream to specify and be determined depending on close card mark, to accelerate view The efficiency that close card mark compares.
In invention, certain programs have specific demand it is customized when, it is not necessary to modify cas system, no replacement is required CAM card, clothes Device be engaged in by modifying the content of transport stream, and carries the close card mark of specified view in the transport stream, can be completed to TV programme version The protection of power, that is to say, that close card identifies as long as formulation view is written in server in the transport stream, and the encryption key of cas system It does not need to be replaced, then subsequent television terminal after receiving transport stream, regards as long as prestoring the close card mark of view with specified Close card mark, can be decrypted, and therefore, the encryption key of transport stream does not become, then the decruption key of television terminal can be direct Transport stream is decrypted, if having changed the close card mark of view in transport stream, television terminal can not be decrypted, and the present invention is by server It formulates and regards close card mark, without regarding close card with television terminal replacement, reduce the cost that television terminal plays TV programme.
The playback method for the TV programme that the present embodiment proposes first is obtained in the play instruction for detecting program to be broadcast The corresponding transport stream of program to be broadcast for taking server to send, and the close card mark of specified view of the program to be broadcast is obtained, Then by it is described it is specified depending on it is close card mark with television terminal install depending on it is close block it is corresponding prestore depending on close card identify be compared, In It is described it is specified depending on close card mark with it is described prestore regard close card identify match when, by it is described transmit be streamed to it is described regard in close card, And based on the transmission stream broadcasting program after the close card decryption of the view, rather than after the change of the copyright of TV programme, Zhi Nengan Fill it is new depending on close card to be decrypted and play program to transport stream, in the present invention, regardless of the copyright of TV programme is changed, As long as the specified of program matches depending on close card mark with the corresponding close card mark of view that prestores depending on close card that television terminal is installed, Ji Kegen According to it is described depending on it is close card be decrypted avoided with playing program TV programme copyright change, it is caused view it is close card frequently replacement, It reduces and plays cost consumed by TV programme.
Further, in order to improve TV programme broadcasting flexibility, TV of the present invention is proposed based on first embodiment The second embodiment of the playback method of program, in the present embodiment, if described, there is currently the prestored informations of the program to be broadcast Table, it is determined that after the step of whether prestoring the specified view close card mark of the program to be broadcast in the prestored information table, The playback method of the TV programme further include:
