## Abstract

The present invention relates to a control method of a broadcasting receiver and a broadcasting receiver adapting the control method. More specifically, the present invention relates to a control method of a broadcasting receiver capable of switching off a power key in a state of display means standing by and switching on the power key in case that a power-key-on is inputted, to improve user convenience.

## Claims

### Claim 1

A control method of a broadcasting receiver comprising:
receiving a power-key-on input from a user;
outputting a standby driving voltage to a microcomputer of a last memory module according to the power-key-on input, if a state of a key-in signal inputted in a microcomputer of a power supply unit according to the power-key-on input is changed;
outputting an AC (Alternating Current) detect signal to the microcomputer of the last memory module in a predetermined time period after outputting the standby driving voltage; and
controlling a display means to power on by the microcomputer of the last memory module, if a time interval between the output of the standby driving voltage and the output of the AC detect signal is a predetermined value or more.

### Claim 2 (depends on 1)

The control method of claim 1, further comprising:
receiving a power-key-off input in a standby state of the display means; and
storing information on the standby state in a memory.

### Claim 3 (depends on 2)

The control method of claim 2, further comprising:
determining the state information stored in the memory if a power-on command is received from a remote controller; and
operating the display means according to the result of the determination of the state information stored in the memory.

### Claim 4 (depends on 2)

The control method of claim 2, further comprising:
determining a final information state stored in the memory, if an AC-power-key-on command is inputted from the user; and
operating the display means according to the result of the determination of the state information stored in the memory.

### Claim 5 (depends on 1)

The control method of claim 1, wherein the controlling step comprises:
controlling the display means to power on by changing the state information of the display means stored in the memory to a display-on or by controlling a IR board, if the time interval between the output of the standby driving voltage and the output of the AC detect signal is a predetermined value or more.

### Claim 6

A broadcasting receiver comprising:
a user interface receiving a power-key-on input from a user;
a power supply unit outputting a standby driving voltage to a microcomputer of a last memory module, if a state of a key-in signal inputted according to the power-key-on input is changed, and outputting an AC detect signal to the microcomputer of a last memory module in a predetermined time period after outputting the standby driving voltage; and
a last memory module powering on a display means, if a time interval between the output of the standby driving voltage and the output of the AC detect signal is a predetermined value or more.

### Claim 7 (depends on 6)

The broadcasting receiver of claim 6, wherein the last memory module receives a power-key-off input in a standby state of the display means and stores information on the standby state in a memory.

### Claim 8 (depends on 7)

The broadcasting receiver of claim 7, wherein the last memory module determines the state information stored in the memory, if receiving a power-key-on command from a remote controller, and operating the display means according to the result of the determination of the state information stored in the memory.

### Claim 9 (depends on 7)

The broadcasting receiver of claim 7, wherein the last memory module determines the state information stored in the memory, if an AC (Alternating Current)-power-key-on command is inputted, and operating the display means according to the result of the determination of the state information stored in the memory.

### Claim 10 (depends on 6)

The broadcasting receiver of claim 6, wherein the microcomputer of the last memory module controls the display means to power on by changing the state information of the display means stored in the memory into a display-on or by controlling the IR board, if a time interval between the output of the standby driving voltage and the output of the AC detect signal is a predetermined value or more.
