Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a time setting method of a television, and more particularly, to a method of automatically setting a time of a television using a real time clock (RTC). A method of setting a time of a television comprising a clock portion and a real time clock portion of a television for the purpose of the present invention, the method comprising: determining whether time information is set in the clock portion of the television; Otherwise, receiving a time update request code from the real time clock unit, and receiving the real time clock data from the television clock unit to set a time. According to the present invention, when the television has a built-in RTC element, the time of the television can be set automatically as soon as the user turns on the power.

Description

How to set the TV's auto time

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a time setting method of a television, and more particularly, to a method of automatically setting a time of a television using a real time clock (RTC). In general, Micom of a television has a visual function and uses it as an on-timer function or an off-timer function. In a conventional TV, the time set by such a timer is returned. As it is set, there is an inconvenience in that the user needs to reset the time, and even though the on-timer is set, the on-timer does not operate because the current time is not set.

The technical problem to be achieved by the present invention is to provide a method for automatically setting the time of the television in the event of an accident in a television with a real time clock (RTC).

1 is a block diagram showing an apparatus for applying the automatic time setting method of a television according to the present invention.

2 is a flowchart showing an automatic time setting method of a television according to the present invention.

In order to achieve the above technical problem, the present invention provides a method of setting a time of a television receiver having a clock of a main unit and a real-time clock of a sub unit, wherein a process of determining whether time information is set in a clock of the main unit of the television receiver Receiving time update request code from the real time clock of the sub unit, and setting the time by the real time clock data of the sub unit and transmitting a timeout code if the time information is not set in the process The automatic time setting method of the TV comprising a.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a block diagram showing an apparatus for applying the automatic time setting method of a television according to the present invention, comprising a clock 112, a television control unit 110 for adjusting a clock with a television microcomputer 114, and a real time clock. Sub (Real Time Clock: RTC) 122 and a central processing unit (CPU) 124 for outputting a real time clock signal to the television microcomputer 112 according to the control signal of the television control unit 110. It consists of a board control unit 120.

2 is a flowchart illustrating an automatic time setting method of a television according to the present invention, a time setting completion determination process 210, a sub board power supply process 220, a time update request code transmission process 230 to a sub board CPU, The step of connecting the RTC time data to the television micom (step 240), determining whether the TV micom has received an end code (250), and the sub-board power-off process (260).

Referring to the operation and effects of the present invention by combining the block diagram of Figure 1 and the flowchart of Figure 2 as follows.

The TV microcomputer 114 of FIG. 1 checks whether the time information to be set in the clock 112 is set during the program execution (step 210). If the TV microcomputer 114 is set, the TV microcomputer 114 continuously executes the main program. If is not set, power is supplied to the sub board 120 having the RTC 122 and the central processing unit (CPU) 124 (step 220) to update the time with the CPU 124 of the sub board 120. The request code is transmitted (step 230). The real time clock 122 in the sub board 120 automatically maintains the date and time.

The TV microcomputer 114 receives data of the real time clock 122 of the sub-board 120 as an input such as a serial data communication port and updates a register of the clock 112 (step 240). Next, the TV microcomputer 114 determines whether the RTC data transfer end code from the sub-board CPU 124 is received (250). If the end code is not received, the TV microcomputer 114 continuously receives the RTC data. The board 120 is powered off and the main program is performed (step 260).

As described above, according to the present invention, when the television has a built-in RTC element, the time of the television can be set automatically as soon as the user turns on the power.
