Embodiment
Technical scheme is described in further detail with reference to the accompanying drawings and detailed description.
Referring to Fig. 1, the figure, which show the present invention, realizes method one embodiment that smart card dynamic plug responds
Flow chart.
As shown in figure 1, in this embodiment, smart card terminal realizes the process step of smart card dynamic plug response such as
Under：
Step 101：Flow starts.
Step 102：Starting up of terminal, preset full terms reception system in initialization terminal.
To allow the compatible a variety of condition receiving systems of terminal, when upgrading when terminal is dispatched from the factory or to terminal,
Preset a variety of condition receiving systems in terminal.For example, all conditions reception system that can be to be commonly used on preset existing market.With
During the using terminal of family, after starting up of terminal, full terms reception system is initialized.
The initialization of condition receiving system refers to that each functional module of terminal-pair condition receiving system is initialized, including
The initialization of intelligent card initialization, the initialization of OS adaptation layers, communication interface initialization, demultiplexing initialization and storing initial etc.
Set.Because the bottom function used when the condition receiving system of different type or producer is developed will not be completely the same, it is at end
Required end application is run in end can also be not quite similar.Different condition reception system is directed to built-in in the terminal
A variety of application programs, development process is complicated, and mutual coordination control can be extremely difficult.On the other hand, although inhomogeneity
The condition receiving system physical layer interface implementation of type is different, but the function that each condition receiving system is realized is to end application
For many general character be present.Based on this, the preferable initialization procedure of the embodiment is：Multiple general-purpose interface letters are set in the terminal
Number, terminal are initialized using each preset condition receiving system of general-purpose interface function pair, simplify terminal software and open
Flow is sent out, improves terminal resource management uniformity and service efficiency.
Specifically, general-purpose interface function includes OS Adapter Layer Interfaces function, the communication that is communicated with smart card connects
Mouth function, demultiplexing interface function and data memory interface function.After starting up of terminal, terminal can call these general-purpose interface functions
Each functional module of each condition receiving system is initialized respectively.
Moreover, to avoid the occupancy to terminal shared interface resource, general-purpose interface function can also include release conditions
The realizing interface function of reception system function.When exiting some condition receiving system, terminal can utilize the realizing interface letter
Terminal resource shared by number release conditions reception system, to improve terminal resource utilization rate.
It should be further stated that in the terminal preset a variety of condition receiving systems the step of be before terminal is dispatched from the factory or
Dispatch from the factory disposable operation performed when carrying out upgrade maintenance during use to terminal, and starting up of terminal, initialization condition connect
Receipts system is the step of being frequently performed during user's using terminal, and the embodiment is completely is illustrated to whole flow process, general
It is put in one step to describe.
Step 103：Judge the type of smart card being currently inserted into terminal.
Although being built-in with a variety of condition receiving systems in terminal, a kind of smart card can only be used every time, using a kind of bar
Part reception system, it is therefore desirable to judge the type of smart card being currently inserted into terminal, it is corresponding with smart card to run
Condition receiving system.
Judgement to smartcard types, it can be resetted by card to realize.Specific implementation process is summarized as follows：To smart card
Perform and reset operation, ATR will be produced and reset response message, adjusted back by message, obtain historical data, the communication protocol in ATR
And the data such as ATR length, according to these data it may determine that going out smart card belongs to which kind of condition receiving system and smart card institute
The host-host protocol of use, namely obtain the type of smart card.
Step 104：Run the corresponding condition receiving system of the type of the smart card with being currently inserted into.
Because all conditions reception system in terminal is initialized in starting up of terminal, therefore, judging
After the smartcard types being currently inserted into, the condition receiving system corresponding with current smart cards and operation can be directly chosen,
So as to realize condition reception.
Exemplified by using set top box as terminal, realize that the process of condition reception is summarized as follows：
Call demultiplexing interface function to filter the TS streams that front end is sent, obtain corresponding Entitlement Control Message
（ECM）And Entitlement Management Message（EMM）.Specifically, set top box describes according to the CA of PMT and CAT tables, obtains EMM's and ECM
Pid value, ECM and EMM are then filtered out from TS streams according to pid value.For ECM the and EMM data that multiple slot be present,
To avoid loss of data, after slot data have been extracted from the background, ECM and EMM number of the first allocating cache quene to extraction
According to being cached.
After ECM and EMM data acquisitions, complete ECM and EMM data pass in being cached by general-purpose interface function
Transport to smart card corresponding to condition receiving system and processing is decrypted.
The decryption processes of smart card are：Smart card reads the individual subscriber distribution key PDK of its memory storage, uses PDK
EMM is decrypted, takes out business cipher key SK；Then, then with SK to ECM decrypt, solve scrambled control word CW.Meanwhile decrypting process
Address, the authorized user message that EMM is included, the program that can be seen such as user or period, the receipts that user pays can also be obtained
Depending on the information such as taking, to realize associated authorization management.
Then, the scrambled control word after decryption processing is supplied to descrambler by general-purpose interface function, to the sound of encryption
Video flowing is descrambled.And by other Entitlement Control Message data and Entitlement Management Message data after decryption processing, such as save
The data such as the program information datas such as mesh source, time, classifying content and program price, mail, fingerprint are converted to conventional data knot
Structure, there is provided give set-top box application program.Here, other Entitlement Control Message data refer to ECM decryption after except scrambled control word it
Outer other information data, these packets contain the program Information Number such as programming source, time, classifying content and program price
According to, it is desirable to provide used to set-top box application program.And in Entitlement Management Message data EMM, not only include mail, fingerprint
Etc. management information data, it is also possible to the programs such as the programming source of the request program such as IPPV, IPPT, time, classifying content can be included
Information data, these data are also required to be supplied to set-top box application program to use.
Step 105：If detecting, the type of the smart card inserted in terminal changes, operation and the intelligence after change
Condition receiving system corresponding to the type of card.
To ensure also realize normal condition reception after smart card is extracted and reinserted, it is desirable in real time to terminal
In smartcard types detected and judged.For example, a time can be preset, judge once at interval of the time.
Or other judgment modes can also be used, specifically refer to the description of Examples hereinafter.When detect smartcard types send out
Changing, then chosen from terminal preset, the condition receiving system that has performed after starting up of terminal initialization with after change
Condition receiving system corresponding to the type of smart card is simultaneously run.
Step 106：Flow terminates.
Hereafter, step 103 is repeated to the process of step 105, until terminal closedown.In this process, initialization is pre-
The process for the full terms reception system put is performed once in starting up of terminal.If restarted after terminal closedown, then weigh
The new process for performing step 102 and step 105.
In this embodiment, first all built-in condition receiving systems are initialized after starting up of terminal, even if smart card exists
Be pulled out in the starting up of terminal course of work and again insertable into addition be replaced, can judge again insertable into smart card class
Type simultaneously runs the corresponding condition receiving system after initialization, startup and initialization is turned back on without terminal, so as to real
Show dynamic plug response of the smart card in the case of terminal is not shut down, improve the speed of terminal response smart card and using intelligence
The convenience that can block.Referring to Fig. 2, the figure shows second implementation of method that the present invention realizes smart card dynamic plug response
The flow chart of example.
As shown in Fig. 2 second embodiment realizes that the process of smart card dynamic plug response is as follows：
Step 201：Flow starts.
Step 202：Starting up of terminal, preset full terms reception system in initialization terminal.
The concrete methods of realizing of the step may be referred to the description of the step 102 in Fig. 1 embodiments.
Step 203：Judge the type of smart card being currently inserted into terminal.
The concrete methods of realizing of the step may be referred to the description of the step 103 in Fig. 1 embodiments.
Step 204：The condition receiving system for selecting the type of the smart card with being currently inserted into corresponding connects for conditions present
Receipts system.
Step 205：Judge whether conditions present reception system is halted state.If so, perform step 206；Otherwise, go to
Step 207.
Because full terms reception system has been performed both by initialization operation after starting up of terminal, and at most have in the same time
One condition receiving system is in running status, also can occupied terminal after the condition receiving system initialization in non-operating state
The resources such as CPU, internal memory.For reduce resource occupation, the embodiment to after initialization condition receiving system set halted state and
Two kinds of different states of normal condition, state can be characterized by the value of the state variable of setting.Wherein, normal condition is finger
All threads of part reception system are in running status, and halted state refers to the kernel main thread pause of condition receiving system
A kind of state.After starting up of terminal initialization, each condition receiving system is in the state of acquiescence, if default conditions are normal shape
State.In this step, the state variable value of conditions present reception system is read, conditions present reception system is judged according to variate-value
In which kind of state.If conditions present reception system is halted state, step 206 is performed；If not halted state, then
Normal condition is expressed as, performs step 207.
Step 206：If conditions present reception system is placed in a suspend state, it is necessary to first recover in conditions present reception system
The main thread of core is running status, and it is normal condition to set conditions present reception system, namely the value of change state variable is
Variate-value corresponding to normal condition.Then, suspend the kernel main thread of other conditions reception system, and these other conditions are connect
Receipts system is arranged to halted state, namely it is variate-value corresponding to halted state to change the value of its state variable.Then, step is performed
Rapid 208.
Due to by the pause of the kernel main thread of non-present condition receiving system, the no longer resource such as occupied terminal CPU, internal memory,
Reduce terminal load, improve resource utilization.Moreover, the condition receiving system of halted state is only to have suspended occupancy resource
More kernel main thread, such as kernel-driven, descrambler, ensure that main thread recovers and whole in the state of terminal is not restarted
Condition receiving system is transferred to some threads of running status still in running status（Such as ECM and EMM analyzing and processing, card driving, insert
Cartoon knows thread of CA kernels etc.）, thus, dynamic plug response of the smart card under terminal not rebooting status is not influenceed.
Step 207：If conditions present reception system is not halted state, it is normal condition to represent its state.For example,
Smart card is inserted after initialization for the first time, so condition receiving system default conditions are normal condition, condition corresponding to smart card
Reception system is normal condition.Or although smart card is the smart card being again inserted, but still it is the previous intelligence used
Card, then condition receiving system corresponding to the smart card is the previous system in running status, then its state is also normal condition.
Regardless of state, if conditions present reception system is normal condition, suspend the kernel master of other conditions reception system
Thread, and these other conditions reception systems are arranged to halted state.Then, step 208 is performed.
Certainly, if smart card is be again inserted and previous identical smart card, other conditions reception system continues
Previous state, still in halted state, then it need not repeat pause and change state variable.
Step 208：Conditions present reception system is run, realizes condition reception function.
The specific implementation of condition reception function refers to the description of the step 104 in Fig. 1 embodiments.
Second embodiment only connects the condition corresponding to current smart cards after full terms reception system is initialized
Receipts system is arranged to running status, to ensure that terminal realizes normal condition reception, and by the part of other conditions reception system
Thread suspends, and so as to reduce terminal threads load, reduces the occupancy to terminal system resource.
Referring to Fig. 3, the figure, which show the present invention, realizes the 3rd embodiment of method that smart card dynamic plug responds
Flow chart.
As shown in figure 3, the embodiment realizes that the process of the method for smart card dynamic plug response is as follows：
Step 301：Flow starts.
Step 302：Starting up of terminal, preset full terms reception system in initialization terminal.
The concrete methods of realizing of the step may be referred to the description of the step 102 in Fig. 1 embodiments.
Step 303：Judge the type of smart card being currently inserted into terminal.
The step is the first judgement carried out after starting up of terminal to smart card.Determination methods are referred in Fig. 1 embodiments
The description of step 103.
Step 304：The condition receiving system for selecting the type of the smart card with being currently inserted into corresponding connects for conditions present
Receipts system.
Step 305：Judge whether conditions present reception system is halted state.If so, perform step 306；Otherwise, go to
Step 307.
Step 306：If conditions present reception system is placed in a suspend state, it is necessary to first recover conditions present reception system
Kernel main thread is running status, and it is normal condition to set conditions present reception system, namely the value of change state variable is
Variate-value corresponding to normal condition.Then, suspend the kernel main thread of other conditions reception system, and these other conditions are connect
Receipts system is arranged to halted state, namely it is variate-value corresponding to halted state to change the value of its state variable.Then, step is performed
Rapid 308.
Step 307：If conditions present reception system is not halted state, it is normal condition to represent its state.Suspend it
The kernel main thread of his condition receiving system, and these other conditions reception systems are arranged to halted state.Then, step is performed
Rapid 308.
Step 308：Run conditions present reception system.
Above-mentioned steps 305 the execution purpose of each step and execution method into step 308 refer to step in Fig. 2 embodiments
205 correspond to description to step 208.
Step 309：Judge whether that effective smart card is reinserted into.If it is, go to step 303；If it is not, perform
Step 310.

Smart card is pulled out, the callback information that feedback intelligent card is pulled out；And if the smart card of insertion is the card of terminal None- identified,
Then feed back the callback information of dead card.In starting up of terminal running, application program can get these callback informations.At end
During the start operation of end, smart card will not be typically inserted into by frequent extraction.In this case, if frequently inserted to current
The smart card entered carries out type judgement, it will takes more terminal system resource.In consideration of it, judge first after starting up of terminal
The type of smart card and after performing condition reception, only gets effective smart card in terminal and is inserted into（Namely by again
Insertion）Callback information when just again perform step 303 judge smartcard types process and subsequently to conditions present reception
The processing procedure of system.
Step 310：Reinserted if there is no effective smart card, then perform normal handling process.
Here normal handling process may include the situation of following several respects：
Terminal does not get any callback information on smart card, shows that smart card is not pulled out or reinserted,
Then continue to run with conditions present reception system.
Terminal gets the callback information that smart card is pulled out, and shows that smart card has been pulled out.If smart card is pulled out
Going out, condition receiving system can not be run, and can not make any processing to each condition receiving system in terminal, and only in terminal circle
