Abstract
The invention relates to the field of set-top boxes, in particular to a system for utilizing a digital television receiving terminal, namely a set-top box, to realize watching authorization. The system comprises a computer, the digital television receiving terminal and a storage device, wherein the computer is provided with specific encryption software; the digital television receiving terminal is used for receiving a digital television signal and outputting the digital television signal to a television to play after the digital television signal is decoded and is provided with specific decryption software; and the storage device, the digital television receiving terminal and the computer are connected with each other through USB interfaces. The system carries out encryption on watching authorization information through the specific encryption software in the computer and transfers the encrypted information into the set-top box through the storage device. Then the set-top box reads the encrypted watching authorization information and controls the play of the television programs according to the authorization information after the information is decrypted. The operation steps of the system are simple and convenient for the adults as parents and have high operability, but have great operation difficulty for children and are not convenient to imitate and break. And the system adopts specific software to carry out authorization, can flexibly control each channel and carries out time-sharing control on each channel.
Description
Technical field
The present invention relates to technical field of digital television set-top, be meant that specifically utilizing receiving terminal for digital television is a kind of method that set-top box realizes watching authorization.
Background technology
TV is the electrical equipment of each family's indispensability, and it also brings some troubles when bringing amusement to people.For example, family has child, because child's judgement and ability of self control are all more weak, therefore must be limited its behavior of seeing TV, and its viewing time etc. is watched and controlled to the program of for example selecting to suit to it.Therefore the receiving terminal for digital television that a kind of father and mother's of having authoring system occurred.But the implementation of existing Digital Television father and mother's authoring system is: at digit receiving terminal by menu operation to the setting that locks of certain channel; Digit receiving terminal is provided with according to the user corresponding television channel is added latching operation.There are two problems in this method: at first, this authoring system locks by the menu operation of digit receiving terminal, and confidentiality is not strong; This authoring system can't carry out the controls playing operation of time segment to certain television channel, and flexibility is less.
Summary of the invention
Technical problem to be solved by this invention provides a kind of good operability, strong security, and the digital television watching authorization method of controls playing content flexibly.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is: a kind of digital television watching authorization system is provided, and described system comprises:
One computer, described computer is equipped with particular encryption software;
One receiving terminal for digital television, be used for receiving digital television signal and decode, a series of actions such as digital-to-analogue conversion, finally export to television for play, described receiving terminal for digital television is equipped with specific decryption software;
One memory device, it is connected with computer as the encrypted medium of computer and receiving terminal for digital television, authorization message is set and encrypts the back storage for the user; Be connected with receiving terminal for digital television, provide authorization message to play for described terminal control television program to described terminal.
Described receiving terminal for digital television adopts digital TV set-top box, which is provided with USB interface, and described memory device is connected by USB interface with set-top box.
Described memory device is connected by USB interface with computer.
Be provided with in the described memory device and encrypt the area stores authorization message, cryptographic acess is passed through in described encryption zone.
Described particular encryption software by cryptographic algorithm, generates the encryption authorization information corresponding with channel according to the channel information and the time control information of user from the computer input.
Compared with prior art, beneficial effect of the present invention is: described system passes through the interior particular encryption software of computer with the watching authorization information encryption, and this enciphered message transferred in the set-top box by memory device, the watching authorization information of set-top box reading encrypted, the deciphering back is by the broadcast of authorization message control TV programme, and its operating procedure is for succinct convenient, workable as father and mother's adult, and operation easier is big for child, is not easy to imitate and crack; And adopt the specific software mandate, can control each channel flexibly, each channel is controlled at times.
Description of drawings
Fig. 1 is that system of the present invention forms the structural representation block diagram;
Fig. 2 is described system works flow process schematic diagram.
Embodiment
Below in conjunction with drawings and the specific embodiments technical solution of the present invention is described in further detail:
As Fig. 1, system of the present invention comprises computer 10, memory device 20, receiving terminal for digital television 30, and digit receiving terminal 30 is provided with USB interface.
As Fig. 2, the course of work of described system is: the user is connected to the USB interface of computer 10 with memory device 20, and the two adopts the communication of Universal USB interface protocol, and computer can be discerned this memory device automatically.The user opens particular encryption software on computers, point out input channel information and time control information (such as the tenth channel according to software operation, can be 7 o'clock to 9 o'clock evening the time of watching), but spanned file storage after this information is encrypted by the cryptographic algorithm of setting by this software.With described file storage in memory device 20.The user is connected in receiving terminal for digital television 30 with memory device 20 again, behind the receiving terminal for digital television identification memory device, reads file in it, and the information Control display device 40 that the deciphering back is passed through after the deciphering is play.
Also can be provided with in the described memory device 20 and encrypt the zone, when the user need open this encryptions zone when operating encrypting the zone, need import password, this password can be by the original setting of the equipment unit of distribution.File after the encryption must be stored in to be encrypted in the zone, and set-top box could be discerned and read, and further increases the reliability of authorization message.And other also chargeable common U disk in zone of this memory device is used.
Defined cryptographic algorithm in the described particular encryption software, this algorithm software can adopt at present ripe various smart card cryptographic algorithm, also can the Custom Encryption algorithm, and those skilled in the art all can realize, therefore repeats no more.
