That is, the signal control method includes determining whether the remote control setting mode key 14 provided on the VSI set 18 is input by the user as the VSI is powered on (step 100). And, if it is determined in the step that the remote control setting mode key 14 is input, and continuously determining whether or not the power key of the remote control for the other company through the remote control receiver 11 of VSI (step 120), If it is determined in the above step that the power key of the third-party remote controller 10 is input, the power key data of the third-party remote controller 10 and the preset power key data format of the preset remote controller mounted on the EPIROM 16 are consistent with each other. Determining whether or not (step 130), outputting an OSD screen indicating that the power key data format matches if the result of the determination (step 140), and power key data of the determination result. If the format is different, outputting an OSD screen indicating that the format is inconsistent (step 150); and subsequently determining whether the remote control setting mode key 14 is re-entered (step 160), and setting the remote control in the step. When the mode key 14 is input again, completing the setting of the third-party remote controller 10 (step 170), and when the setting of the third-party remote controller 10 is completed in the above step, the setting completion message is immediately displayed through the OS screen. The step of outputting (step 180) is made.

In addition, when it is determined that the remote controller setting mode key 14 is input in the above step, the microcomputer 12 continuously determines whether the user inputs the power key of the remote controller 10 for another company (step 120).

At this time, when it is determined that the power key of the third-party remote controller 10 is input, the microcomputer 12 continues to execute the power key data of the third-party remote controller 10 and the power of the preset remote controller mounted on the YPIROM 16. It is determined whether or not the key data formats match (step 130).

As a result of the determination, if it is determined that the power key data matches, the OSD screen indicating the match is output to the TV receiver (step 140). For example, the data format of the power key may be marked as matched or matched.

However, if it is determined that the power key data is inconsistent as a result of the determination, a message indicating the inconsistency may be output to the TV receiver as described above (step 150).

On the other hand, the user checks the message output on the OS screen in order to use the third-party remote control 10 compatible, and if it is confirmed that the message is matched with the remote control setting mode key to complete the setting of the third-party remote control 10 (14) is re-entered.

At this time, the microcomputer 12 of VSI determines whether there is a re-entry of the remote control setting mode key 14 (step 160), and if there is a re-entry, the setting of the remote controller 10 for another company is completed ( Step 170).

In addition, as soon as the setting of the third-party remote controller 10 is completed in this step, the setting completion message is output through the TV receiver (step 180).

For example, a message indicating that the remote control setting is completed is output.

Therefore, when the setting of the third-party remote controller 10 is completed, the power of the VSI is turned on, and as the user presses various function keys of the remote controller 10 for the third-party, the microcomputer 12 on the side of the VSI set 18 is The control signal is sent to each part of the VSI set 18 to perform various functions selected by the user.
