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 CA system condition of different all over China; Apparatus of digital television receiving has proposed the separation between machine and card scheme based on UTI and CI interface, and the UTI scheme is based on general USB interface, and the CI scheme gives the PCMCIA physical interface and defines pin again; Two kinds of scheme common characteristic are to flow to line output and input to data; In kilocalorie (CI card), carry out descrambling, the shortcoming of doing like this is that the cost of kilocalorie is higher, and the cost of kilocalorie has directly improved system cost; All be a no small expense concerning radio and TV operator and consumer, seriously restricted the popularization of kilocalorie product.Along with the appearance of intelligent TV set and the progress of television set chip itself; Can carry out at present the descrambling of data flow in television set inside; For this reason, the separation between machine and card scheme has existed employing ISO7816 interface to read for lesser calorie (CA card) data, carries out the possibility of data de-scrambling with television set; And current kilocalorie is in position of mainstream; And do not have a system compatible kilocalorie and lesser calorie (CA card) simultaneously now, the use that promptly present neither one system can satisfy kilocalorie (CI card) can be satisfied the use of lesser calorie (CA card) simultaneously again, uses the system of kilocalorie all to comprise big card, master chip and pin at present; Big card is used for and big card connection; And comprise a plurality of a plurality of relevant pins of not using pin and being used for linking to each other in the pin with the kilocalorie pin, do not use pin not link to each other, and the relevant pins that links to each other with the kilocalorie pin is connected with master chip with the kilocalorie pin; Use the system of lesser calorie all to comprise master chip, little card and pin, basic identical with the kilocalorie connected mode, but pin definitions is different, and basically all be identical no matter the use kilocalorie still is its master chip of system of lesser calorie.
Summary of the invention
The objective of the invention is to overcome the present 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 that adopts is that CI card and CA card compatible system comprise master chip, big card, CI card and pin; Said pin comprises that kilocalorie relevant pins and kilocalorie do not use pin; The kilocalorie relevant pins comprises power pin, ground wire pin and reseting pin at least, it is characterized in that, also comprises CA card and CA cutting ferrule; Said CA card comprises the pin of CA card; Said CA cutting ferrule and CA card adapt, and the CA card can embed in the CA cutting ferrule, and the CA cutting ferrule that embeds the CA card adapts with big card; The pin of said CA card comprise power pins, wire pin, reset pin and other pins; The power pins of CA card, wire pin and reset pin through the CA cutting ferrule can be respectively with the kilocalorie relevant pins in power pin, ground wire pin and reseting pin be connected, other pins of said CA card and clock pin can not use with kilocalorie respectively through the CA cutting ferrule that the pin of respective numbers is connected in the pin, the pin of said respective numbers is connected with the respective transmissions interface of CA card in the master chip.
Concrete, said CA card is the ISO7816CA card.
Further, the pin of said CI card comprises CI card power pins, CI card reset pin and CI clamping ground pin.
Concrete; Other pins of said CA card comprise data pin and clock pin at least; Said kilocalorie does not use pin to comprise VPP1A pin and VPP2A pin at least, and data pin is connected with the VPP2A pin through the CA cutting ferrule, and the clock pin is connected with the VPP1A pin through the CA cutting ferrule.
The invention has the beneficial effects as follows, through above-mentioned CI card and CA card compatible system, owing to adopt big card and kilocalorie relevant pins etc.; To not influence of kilocalorie (CI card), in addition, for the CA card provides a CA cutting ferrule; This CA cutting ferrule adapts with big card, embed the CA card after, with the power pins in the pin of CA card, wire pin and reset pin respectively with the kilocalorie relevant pins in power pin, ground wire pin and reseting pin link to each other; Do not use pin to link to each other 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 that link to each other with CA card pin do not use the respective transmissions interface of CA card on pin and the master chip to be connected; Reached the compatibility of CI card and CA card; Making system both can use the CI card also can use the CA card, help the popularization of kilocalorie product, also is the space that radio and TV operator and consumer provide free selection simultaneously; Multiplexing power pin, ground wire pin and reseting pin make connection simple relatively.
