The patent No. is 97245594.9, denomination of invention is the Chinese patent of " a kind of television set cipher switch ", introduced a kind of technology,, otherwise made TV power supply be in off-state always if the password of user input correctly then connect TV power supply according to cipher control television set switch.But this technical scheme can only be controlled the switch of television set, can not control the selection of television channel, can not control the purpose that the minor watches unhealthy TV programme.
At present, as shown in Figure 1, some digital TV set-top box are provided as the method that television channel adds a password and prevent the above-described problem from occurring, this password is the initial password that dispatches from the factory, the user can change, but has only a cover password, and password is lost accidentally or forgotten by the user like this, all can not use again, cause the trouble in the use.So, some manufacturer provides a cover standby universal password, as shown in Figure 2, this password at any time can enter this channel, watch the program of this channel, and need not change original code and have the function of resetting this channel password too, when manager's (being generally the head of a family) of household electrical appliances will control that teenage or other members use a certain function of these household electrical appliances in the family, the administrator password that producer provides is learnt by other members, then this people can watch TV programme or carry out other operations by the administrator password that producer provides, because the password that the manager is provided with is not changed, so the manager in such these household electrical appliances of operation can not find, so, the manager that password is set just can't effectively control, and has reduced the fail safe of password.
Summary of the invention
In order to address the above problem, to the invention provides and a kind ofly prevent that other people from making the method for electrical appliance under the ignorant situation of password setting person.
Cipher set-up method in a kind of Digital Television is characterized in that, step 1, and the administrator password that personal identification number that storage user 1 is provided with in the Digital Television and manufacturer provide is used to control other users watching the respective digital television channel; Step 2, user 2 carries out the password input by a cipher input; Step 3 allows this user 2 to watch the TV programme of this channel if this password is consistent with described user's 1 personal identification number, otherwise forwards step 4 to; Step 4, the described administrator password of user's 2 inputs enters this channel; Step 5 requires the new user's personal identification number of these user's 2 inputs when user 2 enters this channel; Step 6, former user 1 personal identification number of storing in the described Digital Television is replaced by the password of firm input if user 2 imports new user's personal identification numbers, and allow this user 2 to watch this channel, otherwise continue to require user's 2 input passwords, and user 2 can't watch this channel.
The administrator password that described manufacturer provides is only by the unique setting of producer.
Described cipher input comprises the button input unit, knob input unit, touch input device.
Beneficial effect of the present invention is; after the use and management password is operated Digital Television; user's personal identification number all can be changed; so just can make the Digital Television user learn that the human administrator password watched this channel TV program timely; can take corresponding measure that user's personal identification number is carried out better protection, to realize to the safer protection of password.
Description of drawings
Fig. 1 is the schematic diagram of prior art single password;
Fig. 2 is the work schematic diagram that prior art has user cipher and administrator password;
Fig. 3 is user search television channel and the work block diagram that password is set;
Fig. 4 is applied to the block diagram of TV for the inventive method.
Embodiment
Below, carry out following detailed description for the present invention in conjunction with the accompanying drawings.
Fig. 3 is user search television channel and the work block diagram that password is set.On the present TV of the manager of household electrical appliances (being the head of a family in this example) or by the TV set-top box television channel searching, such as the channel that searches a special movie, and the film of this cannel broadcast still belongs to and is not suitable for that the minor watches, this manager just selects this channel is encrypted by the feature list on the screen after searching out this channel, and imports corresponding user's personal identification number and preservation.When this manager not on TV next door or when staying out, other members of minor or family turn on TV, be illustrated in figure 4 as the block diagram that the inventive method is applied to TV, select television channel, when the channel of selecting the manager to encrypt since this channel be limited, so do not have image and sound, the dialog box of input password appears requiring on the screen, if the user can enter when knowing gerentocratic personal identification number, and carry out and for example change password, or the routine operation of television set such as channel searching, if the user does not know the personal identification number that the manager is provided with, can not watch this channel TV programme content so, if but this user does not know the personal identification number that the manager is provided with but knows the administrator password that manufacturer provides, then import this administrator password in the password input frame on screen, on screen behind the input manager password, can demonstrate another password input frame again, this input frame is the input frame of new password, the user imports new password in this input frame after, will change the personal identification number that is stored in former user in television set or the set-top box automatically and be the new password of importing, this step is carried out on the backstage, can't help the user and select, also will not watch TV programme less than this channel if the user does not import new password.Because the user has imported new personal identification number and has changed the original personal identification number of manager (head of a family), when this manager selects this channel next time, will find that this gerentocratic personal identification number is changed by others, the administrator password that makes him learn that manufacturer provides is learnt by others, and the administrator password that someone has used manufacturer to provide was watched this television channel, and this makes manager (head of a family) can monitor and improve the fail safe of personal identification number.
Again for example, administrator password is set when dispatching from the factory: 8888, personal identification number: 0000
Can revise personal identification number earlier when leading subscriber (head of a family) uses so: 1234, administrator password can not change, and offers user's (whether be regardless of is the minor).The minor just can't see program owing to do not know this new individual password so.But he can input manager password 8888, and then system wants him to import new personal identification number, imports 2345 such as him, can watch program.Lost efficacy but can find to input original 1234 passwords when the next head of a family enters same program, thereby knew someone's password of correcting one's mistakes, then the minor was educated.
The password that the user of TV too can this user of use and management change of secret code simultaneously.
Beneficial effect of the present invention is, can make electrical equipment manager discovery as early as possible have the people at the use and management password some function of electrical equipment to be used, and has avoided the economic loss that might bring, and the fail safe that has improved password.
Above embodiment only is used to illustrate the present invention, but not is used to limit the present invention.
