When the off time set by the hand-held timer 102 (see FIG. 1), the timer unit 230 outputs a toggle signal, and the controller 240 immediately outputs code information corresponding to the toggle signal. The code information is transmitted in the form of a wireless signal through conversion at the signal output unit 250. The remote controller receiver 1220 of the television 1200 detects a radio signal from the signal output unit 250, converts the radio signal into an electric signal, and transmits the converted signal to the power control unit 1230. Accordingly, the power control unit 1230 controls the power of the television 1200 to be turned on or off by outputting a control signal corresponding to the signal transmitted from the remote control receiver 1220 to the power driver 1210. .

The on / off state checking step (S230) is a step of checking the power state of the television 1200 by detecting on / off state information PI of power transmitted from the remote control transmitter 1240 of the television 1200. . Here, the on / off state information PI transmitted to the remote controller 200 through the remote controller transmitter 1240 is actually transmitted in the form of a wireless signal. First, after the television 1200 is turned on or off in the toggle signal output step S220, the power control unit 1230 detects the power state and outputs the result to the remote controller transmitter 1240. . The remote control transmitter 1240 converts the transmitted on / off state information PI into a wireless signal and outputs the converted wireless signal to the remote control apparatus 200. The power confirmation unit 220 of the remote control apparatus 200 detects a wireless signal containing the on / off state information PI, converts it into an electrical signal, and outputs the result to the timer controller 242. Accordingly, the timer controller 242 detects whether the power of the actual television 1200 is on or off.

The power off step (S240) is a step of re-outputting corresponding code information when the power of the television 1200 is detected to be on. That is, the timer controller 242 re-outputs code information corresponding to the toggle signal input from the timer 230 so that the power of the television 1200 is turned off again. Accordingly, when the television is not turned off by the setting of the self-winding timer 102, the remote controller 200 may re-output code information corresponding to the toggle signal to turn off the television. Will be. On the other hand, when the power of the television 1200 is detected to be in an OFF state, the timer controller 242 determines that the power is already turned off in the toggle signal output step S220 and does not output anything.

As described above, according to the power control method of the television according to another embodiment of the present invention, the timer in a relatively simple manner without installing a separate device for detecting the power state between the television 1200 and the remote control device 200 The functionality can be implemented. In addition, by controlling the on / off state of the television in the on / off state check step S230 after remotely controlling the power of the television in the toggle signal output step S220, more accurate power control is possible.

The controller 340 controls the entire remote control apparatus 300 by outputting code information corresponding to signals output from the key input unit 310 and the timer unit 330. In addition, the control unit 340 outputs a control signal for controlling the timer switch 360 according to the input state from the power confirmation unit 320. In more detail, the controller 340 may include a key input controller 341, a timer controller 342, and a memory 343. The key input controller 341 outputs code information corresponding to the key signal received from the key input unit 310. The timer controller 342 outputs code information corresponding to the toggle signal output from the timer 330. In addition, the timer controller 342 outputs a control signal for controlling the timer switch 360 according to the output state of the power confirmation unit 320. The timer controller 342 outputs a control signal to turn off the timer switch 360 when there is no response from the power confirmation unit 320 for a predetermined time. On the contrary, when the power confirmation unit 320 receives the radio signal TS of the television 1300 and outputs the corresponding information to the timer control unit 342, the timer control unit 342 generates a control signal for turning on the timer switch 360. Output The memory unit 343 stores code information data corresponding to the key signal and the toggle signal.

The signal output unit 350 converts the code information output from the control unit 340 into a wireless signal and outputs the converted wireless signal. Since the signal output unit 350 is substantially the same as the signal output unit 150 of FIG. 2, a detailed description thereof will be made with reference to FIG. 2.

The timer switch 360 may be connected between the timer 330 and the timer controller 342. The timer switch 360 has an on / off state according to a control signal output from the timer controller 342. When the timer switch 360 is turned on, the toggle signal output from the timer 330 may be normally transmitted to the controller 340. On the contrary, when the timer switch 360 is off, the toggle signal output from the timer 330 is not transmitted to the controller 340. Therefore, when the timer switch 360 is turned off, the power supply of the television 1300 is not controlled even if the time set by the hand-held timer 102 (see FIG. 1B) elapses.

As described above, the remote control device 300 according to another embodiment of the present invention includes a timer switch 360 between the timer unit 330 and the control unit 340, thereby providing a remote control unit 1340 of the television 1300.

As shown in FIG. 9, the power control method for a television according to another embodiment of the present invention includes an off time setting step (S310), a television signal receiving step (S320), a timer control step (S330), and a power off step. It may be made through (S340).

The off time setting step (S310) is a step of setting the time when the power of the television 1300 is turned off by controlling the remote controller device 300. In practice, the off time setting step S310 is performed in the same manner as the off time setting step S110 of FIG. 3.

The television signal receiving step S320 is a step of checking a power state of the television 1300 by detecting a wireless signal TS transmitted from the remote controller transmitter 1340 of the television 1300. The remote control transmitter 1340 of the television 1300 receives a control signal containing information according to the on / off state of the power from the power control unit 1330, and outputs a radio signal TS when the power is on. If the power is off, the remote control transmitter 1340 is turned off together with the power to output nothing. The power verification unit 320 detects the radio signal TS of the television 1300, converts the signal into an electrical signal, and outputs the result to the timer controller 342. Accordingly, the timer controller 342 detects whether the power of the actual television 1300 is ON or OFF.

The timer control step (S330) is a step of controlling the operation of the self-winding timer 102 by detecting an on / off state of the power of the television 1300 according to the response state of the power confirmation unit 320. The timer controller 342 outputs a control signal for turning on the timer switch 360 when a signal is detected from the power confirmation unit 320. On the contrary, when a signal is not detected from the power confirmation unit 320 for a predetermined time, the timer controller 342 outputs a control signal for turning off the timer switch 360. That is, when the wireless signal TS is detected from the television 1300 and the power verification unit 320 transmits it to the timer controller 342, the timer controller 342 determines that the power state of the television 1300 is on. The television 1300 is turned off by the self-winding timer 102. On the contrary, if no signal is detected from the television 1300 for a predetermined time, the timer controller 342 determines the power state of the television 1300 to be in an off state and inhibits the operation of the self-winding timer 102.

The power off step (S340) is detected according to the time set in the off time setting step (S310) when the power of the television 1200 is detected to be in an on state and the timer switch 360 remains in the on state. The output toggle signal is transmitted to the timer controller 342 to turn off the power of the television 1300. The timer controller 342 outputs code information corresponding to the toggle signal, and the signal output unit 350 converts the code information into a wireless signal PI and outputs the code information. The wireless signal PI of the remote controller 300 is detected by the remote controller receiver 1320 of the television 1300 and the power is turned off.

As described above, according to the power control method of the television according to another embodiment of the present invention, according to the response state of the television 1300, the on / off state of the power is detected in advance to properly control the operation of the timer unit 330. can do.

Next, a power control method for a television according to another embodiment of the present invention will be described.

10, there is shown a flow chart showing a power control method of a television according to another embodiment of the present invention.

As shown in FIG. 10, the power control method for a television according to another embodiment of the present invention includes an off time setting step (S410), a signal output step (S420), an off timer operation step (S430), and a power off step ( It may be made through S440). Although not shown, the power control method of FIG. 10 is controlled by a toggle signal of a remote control device and a remote control device having a hand-held timer that outputs an off-timer control signal before a predetermined time, and then turns off the power after a predetermined time. Can be made using a television with an off timer.

First, the off time setting step (S410) is a step of setting the time when the power of the television is turned off by controlling the remote control device. The user of the television may set a desired off time by adjusting the rotary knob of the self-timer provided in the remote control apparatus.

The signal output step S420 is a step of outputting an off timer control signal for remotely controlling the television from the remote control device. The off timer control signal output from the self-timer is set substantially before the user-set off time. For example, the remote control apparatus may select an output point of the signal as a point earlier than the origin of the manual timer so that the off timer control signal may be output before (or immediately before) a predetermined time. Here, the output point of the off timer control signal may be selected according to the type of off timer provided in the television. For example, when the off-timer setting time of the television is three minutes, the output point of the off-timer control signal may be set at a point three minutes ahead of the origin of the self-winding timer. The off timer control signal output by the self-timer is converted into code information for controlling the off timer by the control unit and then transmitted to the television as a wireless signal through the signal output unit.

The off timer operation step (S430) is a step in which the off timer of the television operates by the off timer control signal. In practice, when the television is powered off, the off timer does not operate and the television is not affected by the off timer control signal. That is, the off timer operation step S430 proceeds only when the television is powered on. The remote control receiver of the television detects a radio signal (toggle signal) for the off timer operation, converts the signal into an electrical signal, and transmits the signal to the off timer. The off timer may be included in the above-described power control unit, or may be separately installed outside the power control unit to be controlled by the power control unit. The off timer outputs a control signal to the power driver to turn off the television after a predetermined time after receiving the operation signal from the remote controller receiver.

The power off step (S440) is a step in which the power of the television is turned off according to the control signal of the off timer. The off timer control signal for operating the off timer from the remote control device is output a predetermined time ahead of the off time, and the off timer of the television turns off the television after a predetermined time by the toggle signal of the remote control device. Therefore, the power of the television can be controlled at a time set by the user through the remote control device.

As described above, according to the power control method of a television according to another embodiment of the present invention, a separate power information recognition device (illumination sensor of the remote control device, power check unit and television of the remote control device) Remote control transmission, etc.) That is, since a timer that is usually included in a television can be used, there is an advantage in terms of cost.

The present invention is not limited to the above-described specific preferred embodiments, and any person skilled in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention as claimed in the claims. Of course, such changes are within the scope of the claims.
