Including an on / off function returns the step of re-performing the automatic on / off function, which is characterized in that configured.

According to the present invention having the above-described configuration, the control unit counts the time to perform the on / off function when the automatic on / off time, by counting the number of execution of the executed power on function through the on / off execution coefficient unit After a certain number of times, the automatic on / off function is stopped until there is a key input related to power on.

Therefore, when the user does not watch the television receiver while watching for a long time, the automatic on / off function is stopped, thereby preventing unnecessary waste of power.

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

FIG. 2 is an apparatus for explaining a method of suspending an on / off reservation function of a television receiver according to an embodiment of the present invention, and the same reference numerals are assigned to the parts performing the same functions as those of FIG. Is omitted.

In Fig. 2, reference numeral 21 denotes a power-on execution coefficient unit for counting the number of times of automatic power-on, which is, for example, counting one time that power is automatically turned on when the time is counted in the television receiver and the power-on time is reached. Will be stored.

Further, reference numeral 22 executes an on / off function when the automatic on / off function execution time is set by counting the time through the timer 5, and executes power on through the on / off execution coefficient unit 21. After counting the number of times, the remote controller 3 determines whether there is any key input and stops the automatic on / off function if there is no key input. The control unit controls the on / off function to be executed.

Next, the operation of the device having the above configuration will be described with reference to the flowchart shown in FIG. 3.

First, when the auto on / off function of the television receiver is set, that is, when the user presses the auto on / off function key 3c through the remote controller 3, the controller 22 sets the mode state storage unit ( 6), and the on / off time data input thereafter is stored in the data storage unit 8 so that the automatic on / off function is set.

On the other hand, the television receiver having the automatic on / off function is set as described above, the power supply plug (not shown) is connected to the outlet to receive power from the outside control unit 22 by the standby power generated through the standby power supply unit (2) Is in the standby state for controlling the operation of the entire apparatus (ST1 step).

After that, the controller 22 counts the time through the timer 5 (step ST2), and when the TV on time comes (step ST3), the control unit 22 switches on by applying a predetermined control signal to the power supply unit 1 (ST4). step). Therefore, the power from the outside is converted to the power suitable for each device operation through the power supply unit 1 is supplied to the overall device.

Subsequently, the controller 22 performs a normal control process for broadcast signal processing on the basis of a preset broadcast frequency by a previously set channel. In addition, while the broadcast signal processing is performed, the time is continuously counted through the timer 5 (step ST5).

Then, the controller 22 counts the power-on execution through the on / off execution coefficient unit 21 and stores the count value (step ST6).

Subsequently, when the counted power-on execution count is two times (step ST7), the controller 22 determines whether there is a key input related to the television function operation from the remote control device 3 (step ST8). If there is no key input even after a predetermined time, e.g., 1 hour (ST9 step), the execution of the automatic on / off function is stopped in the power driving stop state of the power supply unit 1 (step ST10). The stopped state of the function is maintained until the user turns on the power again through the remote control device (3).

However, if any key input is made through the remote controller 3, the controller 22 executes a function corresponding to the input key input (step ST11), and through the power-on execution coefficient unit 21. It resets the counted number of power-on executions and executes the set automatic on / off function (step ST16).

On the other hand, while the signal processing for the general broadcast is being performed while the counted power-on execution count is not twice, when the time counted by the timer 5 reaches the power-off time (step ST12), The control unit 22 switches off by applying a predetermined control signal to the power supply unit 1 (step ST13).

Thereafter, when a user inputs a key for power-on due to the reason for inputting the power key 3a through the remote controller 3 (step ST14), the control unit 22 sends a predetermined control signal to the power unit 1. In addition to switching on and off, the on / off execution count stored in the on / off execution coefficient unit 21 is reset, and the automatic on / off function that has been stopped is executed again (steps ST15 to ST16). .

That is, according to the above embodiment, the automatic on / off function is executed to count the number of times of power-on execution, and when the counted number of times of power-on execution reaches a predetermined number, it is determined whether there is a key input for executing the television function. If the automatic on / off function is stopped, and there is a key input related to the power on, the television receiver can be realized so that the number of times of power on can be reset and the set automatic on / off function can be executed again.

In addition, this invention is not limited to the said Example, It can variously deform and implement within the range which does not deviate from the technical summary of this invention.

As described above, according to the present invention, when the viewer does not watch the television receiver for a long time, the previously set automatic on / off function can be temporarily stopped to prevent unnecessary waste of power.
