Embodiment

As shown in Figure 1, remote control system comprises digital TV set-top box, television set, remote controller.Remote controller comprises the digital TV set box remote control device of digital TV set-top box configuration itself and the remote controller of other household electrical appliances.Realize coming the control figure TV set-top box, need to have in the digital TV set-top box device of the key value that each electric appliance remote controller key assignments of conversion can discern for this digital TV set-top box with other domestic electrical equipment remote controller.Therefore digital TV set-top box is except that comprising existing infrared signal receiver, final controlling element, comprise the button translating equipment, infrared signal receiver links to each other with final controlling element by the button translating equipment, digital TV set-top box also includes the OSD unit in addition, is used to point out the user to carry out associative operation.

The button translating equipment includes systematic code detection module, remote controller key assignments enquiry module, remote controller key assignments modular converter, study module, memory module (flash), infrared signal receiver links to each other with the systematic code detection module, the systematic code detection module links to each other with remote controller key assignments modular converter by remote controller key assignments enquiry module, remote controller key assignments enquiry module, remote controller key assignments modular converter also link to each other with memory module, study module links to each other with systematic code detection module, memory module respectively, and study module also links to each other with the OSD unit.

At first, the user starts the remotely controlled pattern of digital TV set-top box; Secondly, according to the OSD prompting of digital TV set-top box on television set, the user stores the code value of other domestic electrical equipment remote controller in the digital TV set-top box FLASH into, and is corresponding one by one with keypress function definition in the digital TV set-top box; The 3rd, when other domestic electrical equipment remote controller sent infrared signal, digital TV set-top box was discerned its code value and to the corresponding key function, can be realized the control of other domestic electrical equipment remote controller to digital TV set-top box; Simultaneously on other domestic electrical equipment remote controller, defined a remote control mode operating key, determined it to control other household electrical appliances and digital TV set-top box simultaneously or only control other household electrical appliances.

Each module realizes its function by one or more functions in the button translating equipment.Also need define an array in addition, as k[M] [N], being used for preserving the key assignments that the user imports button, M represents the remote controller number of storable other household electrical appliances, N represents the button of corresponding learning remote control device.The learning remote control device refers to other domestic electrical equipment remote controller of may command digital TV set-top box.Wherein the value of N is more than or equal to the number of all effective efficiency buttons of digital TV set box remote control device, otherwise can't learn the button of all digital TV set box remote control devices, and button of the fixing expression of the value of each N, such as, the numerical key 1 of the corresponding digital TV set box remote control device of N=1; Definite key of the corresponding digital TV set box remote control device of N=20.Define several indexed variables in addition, be used for controlling and whether can learn, whether learn to finish.

When the user changes the set-top box button over to mode of learning, but if a new systematic code and the current learning state that is in, its learning process as shown in Figure 2:

Whether the systematic code detection module detects current remote manipulator system sign indicating number and deposits; If, enter learning program, if not, the prompting input is invalid;

Enter learning program, the study module of digital TV set-top box is imported corresponding button by OSD unit prompting user, the remote controller key sign indicating number is corresponding one by one with the set-top box key set code, and the user imports a button, and study module just is saved in key assignments the fixed position of array.Systematic code must be the systematic code of current learning remote control device in this process, otherwise does not preserve.If the study complement mark is true, represent to learn to finish, study module is preserved the button value of study in Flash, is about to array k[M] [N] preservation, withdraw from mode of learning.

As shown in Figure 3, after top box of digital machine is receiving infrared signal under the non-mode of learning, earlier carry out systematic code and detect, when systematic code is default system sign indicating number or the systematic code of having learnt, then change Normal Response Mode over to by the systematic code detection module:

If current systematic code is the default system sign indicating number, then this signal is directly delivered to Executive Module, if not, then further take a decision as to whether the systematic code of having learnt; Wherein the default system sign indicating number is the systematic code of digital TV set box remote control device;

If the systematic code of having learnt, then signal is delivered to remote controller key assignments modular converter, the preservation key assignments of remote controller key assignments modular converter by memory module is converted to the key value of corresponding digital TV set-top box with the button value of current remote controller, delivers to Executive Module.If not the systematic code of having learnt then is an invalid operation.

If detecting is the remote manipulator system sign indicating number of learning, then return several A (scope [0, M-1]), enter remote controller key assignments enquiry module again and carry out the button value inquiry of this learning remote control device, if the array k[A among the FLASH] [N] preserve this key assignments, be effective button, return the position N of this key assignments in array.If invalid button then is an invalid operation.

Because K[M] corresponding function of each N in [N], the value that from remote controller key assignments enquiry module, obtains inquiring about the N that returns, carry out the button conversion by remote controller key assignments modular converter, the value of N is converted to the keypress function that needs, be about to the key value that the remote controller code value is converted to digital TV set-top box.

Key value after transforming is delivered to Executive Module, so far, just finished the operation of response remote controller key.
