Generally the subcard active mode of employing is now, and subcard is extracted, and inserts the set-top box of master card, and set-top box analyzes this subcard and master card is after pairing is used, to supplement with money to subcard, and subcard successfully activates, and can continue to watch.There are several shortcomings in this active mode: each activation manipulation needs the plug child and parent card, if the activationary time that operator sets is shorter, the action of plug child and parent card will be more frequent, if and have a plurality of subcards, the plug of master card will be more frequent so, have a strong impact on the useful life of smart card and set-top box draw-in groove; Operate inadequate hommization, in digitized today, also need the plug on the hardware to realize in order to activate subcard; In the subcard activation, master card must be extracted, and has affected normally watching of master card set-top box.
Summary of the invention
Technical problem to be solved by this invention is: propose a kind of daughter card activating method of set-top box, solve affecting child and parent card and set-top box draw-in groove useful life, affect the normal rating of master card set-top box, operating the defective of inadequate hommization of existing when activating subcard in the conventional art.
The present invention solves the problems of the technologies described above the technical scheme that adopts: the daughter card activating method of set-top box may further comprise the steps:
A. generate EMM information during front end cas system registration child and parent card and issue, described EMM information comprises EMM style number, female card number, associated sub-card number, check digit and other information of master card;
B. set-top box filters out EMM information according to the smart card numbers that inserts, thereby determines that this smart card is to be master card or subcard;
C. the set-top box of master card is obtained check digit from EMM information, obtains simultaneously the authority of checking check digit;
D. the set-top box of subcard is obtained check digit and is stored from EMM information;
E. be limited after set-top box audience program a period of time of subcard, prompting need to reactivate;
F. the user checks check digit by the set-top box of master card, input validation position on the set-top box of subcard;
G. the set-top box of subcard is transferred the check digit of storage, and with step f in the check digit inputted compare, if both are identical, then antithetical phrase sticks into line activating, otherwise will not activate.
Further, also comprise step h: the front end cas system is to the check digit regular update in the EMM information.
Among the step a, described out of Memory comprises the blanking time of activation, the time that prompting activates, the time period of carrying out activation manipulation.
The invention has the beneficial effects as follows: subcard activates the useful life that simply, can not affect child and parent card and set-top box draw-in groove, also can not affect the normal rating of master card set-top box, and operation possesses hommization.
