Step 432 is carried out infrared.
Step 433, receiver receives infrared signal.
In this step, the infrared radiation receiving circuit by receiver receives the infrared signal that launches from telepilot.
Step 434 forms the message parcel by carrying out demodulation with door.
In this step, to receiving infrared signal, to carry out and a door demodulation, corresponding formation is based on the message of first kind message parcel or based on the message parcel of the second class message.
Step 435 is judged type of message from zone bit.
In this step, being the standard message form with message is example, type of message is judged, thereby realized the sectional type decoding, in this embodiment, if zone bit is identified as " 0 ", then enters step 441; If zone bit is identified as " 1 ", then enter step 451.
Step 441 is judged as first kind message, represents key controlled incident.
Step 442 responds in the mode of simulating keyboard.
In this step, be judged as first kind message after, the true form in this first kind message is parsed, inquire corresponding key assignments, finish the process of controlling input response (virtual be KeyEvent), therefore realized remote control thereof according to keyboard mode.
Step 451 is judged as the second class message, and the expression touch pad is controlled incident.
Step 452 responds in the mode of analog mouse.
In this step, be judged as the second class message after, the true form in this second class message is parsed, call the relative program of analog mouse response, realize the response of analog mouse mode.
Step 453 is judged the method for operation by " navigation/hand-written " mode bit of inquiring about in the second class message.
Should " navigation/hand-written " mode bit being that " hand-written/navigation " button input by telepilot shown in Figure 3 forms, be 0 under the default conditions, realizes switching mutually by " hand-written/navigation " button.If when the touch pad input signal, " hand-written/navigation " button is chosen as navigation mode, for the true form information (in the message field (MFLD)) in the second class message, will decode with the absolute position; If when the touch pad input signal, " hand-written/navigation " button is chosen as hand-written pattern, for the true form information in the second class message, will decode with relative position.In this step, by inquiring about in the second class message " navigation/hand-written " the mode bit judgement method of operation, if " navigation/hand-written " mode bit is " 0 ", then enters step 461; If " navigation/hand-written " mode bit is " 1 ", then enters step 471.
Step 461, touch point position information adopt the relative position decoding.
In this step, need carry out the relative position decoding to the entrained positional information of true form, and then form the incident that a mouse moves, therefore, the user can finish the operation of similar mouse on telepilot, easily realize function selecting etc.
Step 471, touch point position information adopt the absolute position decoding.
In this step, need carry out absolute position decoding to the entrained positional information of true form, and then come painted track is responded and discerns with the hand-written program of mouse, obtain character input response.Therefore, the user can easily finish the character information input on telepilot.
So far, this embodiment remote control thereof finishes.Need to prove that in this embodiment, the step after above step 434 and the step 434 is all finished with its clients corresponding software program by the combination of household PC main frame; In other another embodiment, can be by the receiver of the corresponding hardware configuration of design, the step after performing step 434 and the step 434.
Under situation without departing from the spirit and scope of the present invention, can also constitute many very embodiment of big difference that have.Should be appreciated that except as defined by the appended claims, the invention is not restricted at the specific embodiment described in the instructions.

(9) judge type of message, if be judged as first kind message, represent key controlled incident, then the mode with simulating keyboard responds; If be judged as the second class message, the expression touch pad is controlled incident, and then the mode with analog mouse responds;
Wherein, described step (1a) is arranged side by side to the process of step (4c) to the process and the step (1b) of step (1c).
13. a remote control thereof as claimed in claim 12 is characterized in that, when responding in the mode of analog mouse, judges the method for operation by " navigation/hand-written " mode bit of inquiring about in the second class message; If " navigation/hand-written " mode bit is " 0 ", represent navigation mode, touch point position information adopts the relative position decoding; If " navigation/hand-written " mode bit is " 1 ", represent hand-written pattern, touch point position information adopts the absolute position decoding.
