Description
Technical field
The present invention relates to digital television techniques, particularly the compatible technique of CI card and CA card.
Background technology
In order to adapt to the different situation of CA system all over China, apparatus of digital television receiving has proposed the separation between machine and card scheme based on UTI and CI interface, the USB interface of UTI scheme based on general, CI scheme gives PCMCIA physical interface and redefines pin, the common feature of two schemes is to flow to line output and input to data, in kilocalorie (CI card), carry out descrambling, the shortcoming of doing is like this that the cost of kilocalorie is higher, the cost of kilocalorie has directly improved system cost, it concerning radio and TV operator and consumer, is all a no small expense, seriously restricted the popularization of kilocalorie product.Along with the appearance of intelligent TV set and the progress of television set chip itself, at present can carry out at inside television the descrambling of data flow, for this reason, separation between machine and card scheme has existed employing ISO7816 interface to read for lesser calorie (CA card) data, with television set, carry out the possibility of data de-scrambling, and current kilocalorie is in position of mainstream, and do not have now a system compatible kilocalorie and lesser calorie (CA card) simultaneously, it is the use that use that present neither one system can meet kilocalorie (CI card) can meet again lesser calorie (CA card) simultaneously, use at present the system of kilocalorie all to comprise large card interface, master chip and pin, large card interface is for being connected with kilocalorie, and in pin, comprise a plurality of pin and a plurality of relevant pins for being connected with kilocalorie pin do not used, do not use pin not to be connected with kilocalorie pin, and the relevant pins connected with kilocalorie pin is connected with master chip, use the system of lesser calorie all to comprise master chip, little card interface and pin, basic identical with kilocalorie connected mode, but pin definitions is different, and no matter use kilocalorie or its master chip of the system of lesser calorie is substantially all identical.
Summary of the invention
The object of the invention is to overcome the current neither one system shortcoming of compatible kilocalorie and lesser calorie simultaneously, a kind of CI card and CA card compatible system are provided.
The present invention solves its technical problem, the technical scheme adopting is, CI card and CA card compatible system, comprise master chip, large card interface, CI card and pin, described pin comprises that kilocalorie relevant pins and kilocalorie are not used pin, kilocalorie relevant pins at least comprises power pin, ground wire pin and reseting pin, it is characterized in that, also comprise CA card and CA cutting ferrule, described CA card comprises the pin of CA card, described CA cutting ferrule and CA card adapt, CA card can embed in CA cutting ferrule, the CA cutting ferrule that embeds CA card adapts with large card interface, the pin of described CA card comprises power pins, ground wire pin, reset pin and other pins, the power pins of CA card, ground wire pin and reset pin by CA cutting ferrule can be respectively with kilocalorie relevant pins in power pin, ground wire pin and reseting pin connect, other pins of described CA card and clock pin can not used the pin of respective numbers in pin to be connected with kilocalorie respectively by CA cutting ferrule, the pin of described respective numbers is connected with the respective transmissions interface of CA card in master chip.
Concrete, described CA card is ISO7816CA card.
Further, the pin of described CI card comprises CI card power pins, CI card reset pin and CI card grounding pin.
Concrete, other pins of described CA card at least comprise data pin and clock pin, described kilocalorie is not used pin at least to comprise VPP1A pin and VPP2A pin, and data pin is connected with VPP2A pin by CA cutting ferrule, and clock pin is connected with VPP1A pin by CA cutting ferrule.
The invention has the beneficial effects as follows, by above-mentioned CI card and CA card compatible system, owing to adopting large card interface and kilocalorie relevant pins etc., on not impact of kilocalorie (CI card), in addition, for CA card provides a CA cutting ferrule, this CA cutting ferrule adapts with large card interface, embed after CA card, by the power pins in the pin of CA card, ground wire pin and reset pin respectively with kilocalorie relevant pins in power pin, ground wire pin and reseting pin are connected, do not use pin to be connected with kilocalorie other pins in the pin of CA card again, avoided possible the influencing each other on circuit of kilocalorie and lesser calorie, and these kilocalories connected with CA card pin are not used pin to be connected with the respective transmissions interface of CA card on master chip, reached the compatibility of CI card and CA card, make system both can use CI card also can use CA card, be conducive to the popularization of kilocalorie product, the space of free selection is also provided for radio and TV operator and consumer simultaneously, multiplexing power pin, ground wire pin and reseting pin, make to connect relatively simple.
