Abstract
The invention relates to a method capable of controlling the receiving information safety of digital TV terminal through modifying the software and hardware of the digital TV terminal in the application of digital TV. According to the method, the main chip of the prior digital TV terminal is replaced by a chip with descrambling function, and the software stored in a FLASH storage is divided into three parts, i.e. a control program, status messages and program parameters; the control program is solidified into an OTP storage and does not allow a user to modify the control program of a digital set-top box (STB); a serial EEPROM is adopted as a state information storage mainly used to store the state information before shutdown such as program, volume, interface style, game record and learning record as well as the favorite program parameters of a user; moreover, the program parameters are set in an IC card by broadcasting and TV administration section. Because a user can not modify the OTP storage and the IC card, the invention ensures the safety of the receiving information of digital TV terminal.
Description
Technical field:
The present invention relates in the digital television application, by change to digital TV terminal software, hardware, method that can control figure television terminal received information safety.
Background technology:
In recent years, the Digital Television development has been widely applied to huge numbers of families rapidly.There is administrative restriction in country to digital television broadcasting program, forbids rating overseas program and other illegal satellite TV signals.Stipulate clearly in State Council's 129 commands and the industrial products production licence management rules that the product that the manufacturing enterprise through permitting produces must not preset program overseas, must not be with the blind function of sweeping of program overseas.
But, because the digital TV terminal that the user is received satellite programming lacks effectively management, cause a lot of users can on terminal, search for overseas program and other illegal TV programme privately, China people's culture and education there is negative effect.
In existing anti-non-technology, modes such as pair program encryption are arranged, but fail safe is not high, behind the main program of change receiving terminal, be easy to crack, and implementation procedure is not had an economy yet.
Summary of the invention:
In order to address the above problem, to the invention provides a kind of change of passing through digital TV terminal software, hardware, thereby reach the method for effective control figure television terminal received information safety.
The present invention is achieved in that
A kind of method of control figure television terminal received information safety, be that master chip with the conventional digital TV terminal is replaced with the chip with descrambling function, and the software of FLASH memory stores is resolved into 3 parts promptly: control program, state information, program parameter, control program is cured in the otp memory with the master chip plastic packaging, perhaps make the independent and master chip outside of otp memory, its objective is not allow the user that the control program of top box of digital machine is made amendment.Serial EEPROM is as state information memory, and the main state informations such as the preceding program of seeing of shutdown, volume, look ﹠ feel, game records, learning records of preserving also can be preserved some user's favorite program parameters; Program parameter then is arranged in the IC-card by broadcasting and TV administrative department.
Above-mentioned IC-card satisfies the ISO-7816 agreement, uses the COS that meets the PBOC standard of watchdata, by the extraneous security control with the card data of standard authentication algorithm assurance of 3DES, guarantees the safety of data in the card once more by data in the privately owned algorithm for encryption card.Data are write by the special card device of writing in the card, after the relevant parameter fileinfo is write, without permission, all can not revise sticking into row.If changed information, must write in special use can changed information under card device and the certain authority permission.
This intellective IC card program parameter of can writing direct, as condition of acceptances such as rating classification, regional locations, OTP guarantees the uniqueness of program parameter according to solving correct programme information according to the IC-card condition of acceptance, and promptly this class receiver is merely able to watch the TV programme of appointed program parameter classification.The user does not have authority that IC-card is operated, and IC-card can only be operated with special read write line by public institutions such as broadcasting and TV, thereby has made things convenient for the management to the user, has guaranteed the fail safe of rating.
Patent of the present invention is cured to system's main program in the OTP module, once depositing in, just can not change; And on the top box of digital machine function setting, cancel the function that all search automatically, manual search etc. can be searched for platform or add program, prevent that the user from receiving program overseas voluntarily.
Description of drawings:
Fig. 1 is the structural representation of conventional digital TV terminal
Fig. 2 is the structural representation of digital TV terminal of the present invention
Embodiment:
The present invention is described further below in conjunction with accompanying drawing.
The main drawback of conventional digital TV terminal is: because F1ash is as program storage, the user can carry out operations such as programme information change, program upgrade endways, and sweeping for the user is blind provides possible.
Accompanying drawing 2 is digital TV terminal structural representation of the present invention, it has made creationary improvement on the basis of conventional digital TV terminal, the software of FLASH12 memory stores is resolved into 3 parts promptly: control program, state information, program parameter, control program is cured in the otp memory 4, otp memory can be with the master chip plastic packaging, also can make the independent and master chip outside of otp memory, its objective is not allow the user that the control program of top box of digital machine is made amendment.Serial EEPROM 6 is as state information memory, and the main state informations such as the preceding program of seeing of shutdown, volume, look ﹠ feel, game records, learning records of preserving also can be preserved some user's favorite program parameters; Program parameter then is arranged in the IC-card 8 by broadcasting and TV administrative department.
Above-mentioned IC-card satisfies the ISO-7816 agreement, uses the COS that meets the PBOC standard of watchdata, by the extraneous security control with the card data of standard authentication algorithm assurance of 3DES, guarantees the safety of data in the card once more by data in the privately owned algorithm for encryption card.Data are write by the special card device of writing in the card, after the relevant parameter fileinfo is write, without permission, all can not revise sticking into row.If changed information, must write in special use can changed information under card device and the certain authority permission.
This intellective IC card program parameter of can writing direct is as condition of acceptances such as rating classification, regional locations.OTP guarantees the uniqueness of program parameter according to solving correct programme information according to the IC-card condition of acceptance, and promptly this class receiver is merely able to watch the TV programme of appointed program parameter classification.The user does not have authority that IC-card is operated, and IC-card can only be operated with special read write line by public institutions such as broadcasting and TV, thereby has made things convenient for the management to the user, has guaranteed the fail safe of rating.
The present invention can prevent effectively that by main program being cured in the otp memory that can not change stored information the terminal use from arbitrarily changing main program.Simultaneously, to the unified IC-card of allotting by radio and television departments that provides of each terminal use with the independent program parameter.Because IC-card must have special use to write the card device and certain authority could be changed, can guarantee that program that the terminal use watches through the IC-card unified management, has guaranteed the safety of the information of watching.
