Pattern storage module 206 is used to store the work at present pattern of TV remote controller 200.As indicated above, TV remote controller 200 can be operated under common and two kinds of mode of operations of children.Under general mode, TV remote controller 200 is operated under the routine work state, and its various functions all can normally realize.Under child mode, the signal sending function of TV remote controller 200 will be restricted, thus the playing function of restriction television set.Child mode aims at designed for children, so that the head of a family can control children's TV reception.
Should note, for preventing that thereby children from directly walking around the child mode function that is provided with on the TV remote controller at the enterprising line operate of television main, this TV remote controller is being arranged on child mode following time, TV remote controller will be sent the television set lock control signal, television main is locked, in this case, television main will only can be controlled by this TV remote controller, thus, can prevent just that children from walking around this TV remote controller and directly at the enterprising line operate of television main.
For preventing that children are revised as general mode with the work at present pattern from child mode, can adopt the mode of " combination button+hide menu " that the work at present pattern is shown and revise.For example, can come the trigger mode modify instruction, eject the mode of operation setup menu, revise the work at present pattern then by specific combination button (for example a certain function key+numerical key).
As indicated above, at child mode, the accumulative total of every day watches that duration, start period and optional channel all will be controlled, and these functions are to realize by following start period memory module 208, timer module 210, the children's channel memory module 212 that will describe.In addition, also can realize the keyboard lockout function by keyboard state memory module 214.
Record beginning and end time start period that sets in advance in the start period memory module 208, be used to define the concrete time period that to start shooting under the child mode.Can set beginning and end time period of starting shooting according to concrete broadcast time and program length such as but not limited to children's programs.Also be provided with the first starting logo position in the start period memory module 208, be used to show the current start condition that whether satisfies.Be operated in child mode following time, whether the start 208 automatic real-time inspection current time of period memory module are in the available machine time section, if then the first starting logo position is set to 1, otherwise the first starting logo position is set to 0.
For preventing that children from prolonging the start period voluntarily, the mode that can adopt " combination button+hide menu " shows start beginning and end time period and revises.For example, can trigger start by specific combination button (for example a certain function key+numerical key) and the period instruction is set, eject start period setup menu, revise start beginning and end time period then.
Timer module 210 is used to write down accumulative total start duration that is in child mode on the same day in following time in each moment.It should be noted that timer module 210 only writes down each accumulative total start duration constantly on the same day, in the zero hour of next day, the accumulative total of record start duration is with automatic clear.Simultaneously, store the duration threshold value in the timer module 210, be used to define the child mode the longest available machine time of following every day.Also be provided with the second starting logo position in the timer module 210, be used to show the current start condition that whether satisfies.Be operated in child mode following time, whether the current accumulative total of the timer module 210 automatic real-time inspections duration of starting shooting surpasses the duration threshold value, if then the first starting logo position is set to 0, otherwise the first starting logo position is set to 1.
For preventing that children from increasing the duration threshold value voluntarily, can adopt the mode of " combination button+hide menu " that the duration threshold value is shown and revise.For example, can trigger the duration threshold value by specific combination button (for example a certain function key+numerical key) instruction is set, eject duration threshold value setup menu, revise the duration threshold value then.
Children's channel memory module 212 is used to store the channel of the children's channel that sets in advance.Under child mode, the channel that can Gong watch only limits to children's channel, promptly can only select channel from children's channel memory module 212.Similarly, also can comprise adult's channel memory module (not shown), the channel that is used to store the adult's channel that sets in advance.Under child mode, adult's channel must just can be watched by inputing correct password.In addition, adult's channel memory module also can be set to only store the limiter stage channel channel of (comprising pornographic, violent content etc. as the program that broadcasts in the channel), in this case, the channel of adult's channel memory module stored all can't be play under any pattern.
For preventing that children from increasing children's channel voluntarily, can adopt the mode of " combination button+hide menu " that children's channel is shown and revise.For example, can trigger children's channel by specific combination button (for example children's key or a certain function key+numerical key 1 or other numerical keys) instruction is set, eject the children's channel setup menu, revise children's channel then.
Keyboard state memory module 214 is used to store the current state of TV remote controller 200 keyboards.The keyboard of TV remote controller 200 can be operated under locking and the non-locking two states.Unlock state matching convention operating state, each button of TV remote controller 200 keyboards all can operate as normal in this state.And the corresponding keyboard lock function of lock-out state, in this state, many buttons of TV remote controller 200 keyboards (closing key as switch key, numerical key etc.) are with disabled or change function.Because the push button signalling 218 that button triggered when being pressed is corresponding with key command, therefore can in the specific implementation process, help realize the keyboard lockout function by the structure of revising the key command correspondence table of storage in the push button signalling parsing module 202.For example, the key command correspondence table can adopt down array structure:
| Button | Key command | Lock token |
Table 2
Wherein whether lock token is used to identify this key command and should be performed under lock-out state, and if not, then push button signalling parsing module 202 can not send this key command.
For preventing that children from changing unlock state into from being about to lock-out state, can adopt the mode of " combination button+hide menu " that keyboard state is shown and revise.For example, can trigger keyboard state by specific combination button (for example children's key or a certain function key+numerical key 1 or other numerical keys) instruction is set, eject the keyboard state setup menu, revise keyboard state then.Signal transmitting module 220 is used to receive the various command that central controller 204 sends, and sends corresponding control signal 220.
