Description
Technical field
The utility model belongs to field of television play, particularly a kind of circuit family multimachine TV user, that be used for the mandate of cable TV scrambling and descrambling composite aircraft that is applicable to.
Background technology
The analog catv interference blanking system transmits in CATV (Cabae access television) cable access TV network by cable TV signal being encrypted the back at front end mostly at present, just can watch after user side is installed the descrambler deciphering.The mandate of legal descrambler (user who registers and pay dues) sends the key mode by the addressing main frame by special addressing frequency can be decrypted it to coded signal, thus the right that the user is obtained watch.
At present increasing family has had the television set more than, and at this situation, most manufacturer adopts the solution of composite aircraft.The descrambler that is about to registered user's a television set is set at machine tool, and the descrambler of this other television set of user is its handset, and handset is through just watching the programme signal deciphering after the mandate of machine tool.Its objective is that all television sets that should guarantee validated user can both watch coded signal deciphering, preventing again that the disabled user from obtaining the authorization with the name of validated user handset watches that freely the irrational like this phenomenon of program occurs, and causes the loss of cable TV station's license fee.
Primary and secondary type descrambler adopts the IC-card mode to authorize mostly at present.Be the user when handling registration, according to the quantity definition machine tool of its television set and the quantity of handset, cable television operators be TV user custom authorization IC-card in view of the above, and corresponding with it machine tool of granting and handset.When TV user is used IC-card is inserted in the draw-in groove of handset so that handset is authorized.The major defect of IC-card mode mandate is a poor stability, can massive duplication after in case IC-card is decrypted, be clone's descrambler handset mandate, can cause large-area illegal viewer to produce like this, will cause tremendous loss to cable television operators undoubtedly.Make the IC-card authorization can't prevent that still the disabled user from obtaining the authorization with the name of validated user handset, and the IC-card authorization need when registering, TV user customize, and has increased workload and the operating time of cable television operators, and unfavorable for promoting; The cost of IC-card itself is also high, easy to wear, also brings bigger financial burden and uses inconvenience to TV user.
Summary of the invention
Existingly carry out the weak point that the composite aircraft mandate causes defective, enforcement and the use inconvenience etc. of poor stability in order to overcome by the IC-card mode, the purpose of this utility model, just need restudy a kind of new authorization, be to provide a kind of purpose that makes handset obtain the machine tool mandate and cable TV encrypting signal descrambling realized watch by a particular dispenser.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of circuit arrangement that is used for the mandate of cable TV scrambling and descrambling composite aircraft, comprise wired TV RF input port, the radio-frequency (RF) output end mouth, descrambler machine tool and coupled descrambler handset, it is characterized in that, the TV signal that is entered by this rf inputs mouth is connected to a composite aircraft tailored version distributor, this distributor one end is connected to the feeder line that an only permission of being sent by the descrambler machine tool is passed through with the low-frequency digital signal form, the other end is connected to by same feeder line has the descrambler handset of accepting the machine tool authorization message, respectively includes the descrambling circuit part in its machine tool and the handset, single-chip microcomputer SCM part and isolation module; Described machine tool and the handset radiofrequency signal after with descrambling is guided each television set into by the radio-frequency (RF) output end mouth.
At work, each self-contained isolation module is subjected to the control of microprocessor in machine tool and the handset, and strobes, and it only allows low-frequency digital signal to pass through.Authorization message is sent from machine tool with the form of low-frequency digital signal, handset has the function of accepting the machine tool authorization message, distributor is according to how many designs of user's handset quantity, described tailored version distributor, can be two distributors, three distributors, its scope is two to eight distributors, distributor is except that having general catv distributor function, have low frequency signal concurrently and cross the function of fluidic distributor, it can allow to be transmitted between subscribers feeder by the low-frequency digital signal that contains authorization message that machine tool sends.
When TV user was paid dues registration, cable television operators can allot the handset of machine tool and respective numbers by the TV quantity of TV user man, and each machine tool and handset all have independently addressing numbering.Behind the distributor that the address signal that the cable TV signal of scrambling and addressing main frame send enters by catv network, thereby the address signal that is assigned to machine tool is accepted to obtain the authorization by machine tool; Machine tool could be deciphered scrambled signals after handset is authorized by the subscribers feeder, distributor and the subscribers feeder that is connected with handset that are connected with the distributor transmission authorization signal to handset.The distributor of particular design has low frequency signal overcurrent distributor function concurrently, and its effect is to transmit direct current low frequency authorization signal between machine tool and handset.
The beneficial effects of the utility model are that this device can avoid IC-card or other authorizations to use the inconvenience that causes to TV user when guaranteeing scrambled television signal safety of transmission fully.Do not use IC-card then not exist IC-card is decoded and duplicated the problem of usurping, illegally make line cause signal attenuation apart from increase from distributor connexon chance, thus the meaning of losing.Virtual network operator need not customize IC-card for it when the user registered, and saved effort and time, and helped promoting.User side is installed and is connected fast simply, only needs to change the distributor of user family; Owing to do not use the IC-card mode, the back mandate is installed carries out automatically, need not TV user and participate in, do not need to change its use habit fully.
The utility model is described in further detail below in conjunction with drawings and Examples.
