If the input for the time adjustment is commanded from the remote controller 102 during the standby of the input (step 206), the microcomputer 208 determines in step 208 whether the internal soft timer 104a or the timer 128 The current time and the time data of the additional information decoded by the decoder 118 are read and compared.

As a result of the comparison, if the current time of the timer 104a or 128 and the time data of the additional information coincide with each other ('YES' in step 210), the microcomputer 104 starts to wait for a subsequent time adjustment command If the current time of the timer 104a or 128 does not match the time data of the additional information (NO at step 210), the microcomputer 104 proceeds to step 212 to update the time data of the additional information So that the current time of the soft timer 104a or the timer 128 is added or subtracted.

On the other hand, if the automatic time adjustment mode is set by the remote controller 102 in step 202, the microcomputer 104 proceeds to step 214 to set a time interval (for example, 1 to 23 hours) for execution of the automatic time adjustment mode And proceeds to step 216 where it is determined whether the counting result of the soft timer 104a or the timer 128 is an automatic time adjustment point of the set interval.

As a result of the determination, when the counting time of the timer 104a or 128 corresponds to the set automatic adjustment time, the microcomputer 104 sets the current time of the timer 104a or 128 and the decoder 118 And compares the decoded time data DA.

As a result of the comparison, when it is not necessary to adjust the current time of the timer 104a or 128, the microcomputer 104 returns to step 216 to determine the arrival of the set automatic time adjustment interval, 104a or 128 is not in agreement with the time data of the additional information, the microcomputer 104 proceeds to step 222 and determines whether or not the timer 104a Or < / RTI > 128).

In the above description, the automatic adjustment is performed by comparing the time of the timer 104a or 128 with the time data of the additional information. However, if necessary, the current time of the timer 104a or 128 and the time of the additional information Time data may be generated as a character signal in the OSD processing unit 122 and displayed on the screen so that the viewer may perform manual adjustment by the remote controller.

As described above, according to the automatic time adjustment device of a television capable of receiving satellite broadcasts according to the present invention, when the current time of a soft timer or a hardware timer is calculated on the basis of time data included in a satellite broadcast program, It is possible to provide an accurate time data to the calculation of the accurate viewing time and the cost of the commercial satellite broadcasting channel while eliminating the influence on the viewing of the broadcasting program due to the timing error of the timer .
