First, the key input unit 100 includes a plurality of function keys including a power on / off key, and generates and provides a key signal corresponding to a user's key operation to the system controller 200.

The system controller 200 controls the overall operation of the optical disc player 300 in response to a key signal provided from the key input unit 100 and a signal provided by each component of the optical disc player 300, and in particular, the key input unit. When the power-off key signal is applied from the device 100, the time when the power-off key signal is applied is compared with a predetermined time, and when the confirmation key signal is not applied from the key input unit 100 for a predetermined time, the optical disc player 300 Control the power supply unit 600 to cut off the power supplied to.

The optical disc player 300 performs an overall operation of the optical disc player 300 such as playing a disc under the control of the system controller 200.

The counter 400 counts the time from when the power-off key signal is applied from the key input unit 100 under the control of the system control unit 200, and provides the counted time information to the system control unit 200. .

The storage unit 500 stores predetermined character information that is output to the OSD screen to confirm the power-off. Also, after the power-off key signal is applied to the system controller 200, the storage unit 500 stores the character information from the key input unit 100. A predetermined waiting time for waiting to be applied to another key signal is preset and stored.

The power supply unit 600 supplies predetermined power required for the optical disc player 300 to operate to each component member constituting the optical disc player 300 under the control of the system control unit 200.

Under the control of the system controller 200, the OSD processing unit 700 OSD-processes a message for confirming power-off drawn from the storage unit 500 and displays the message on a monitor (not shown).

Hereinafter, the power-off confirmation method of the optical disc player according to the present invention implemented in the hardware composed of the above-described members will be described in detail with reference to FIG.

2 is a detailed flowchart illustrating a power off confirmation method of an optical disc player according to the present invention.

First, when the optical disc player 300 is performing the general operation of the optical disc player 300 in a power-on state (S10), a power off key signal is generated from the key input unit 100 and provided to the system controller 200 ( S20), the system control unit 200 extracts the corresponding character information from the storage unit 500 and outputs the extracted character information in order to output a message confirming whether to power off the optical disc player 300 to the OSD screen. The OSD processor 700 is controlled to output the OSD screen.

Accordingly, the OSD processing unit 700 OSD-processes predetermined character information for confirming whether to power off the optical disc player drawn out from the storage unit 500 under the control of the system control unit 200. ) Is displayed on the OSD screen (S 30).

In addition, the system controller 200 proceeds to step S30 at the same time when the power-off key signal is applied from the key input unit 100 in step S20, and causes the count from the time at which the power-off key signal comes in. The counter 400 is controlled to count.

The counter 400 controls the time from the time when the power-off key signal is applied from the key input unit 100 to the system control unit 200 under the control of the system control unit 200, that is, the power-off key from the key input unit 100. The elapsed time after the signal is applied is counted (S 40).

On the other hand, the system controller 200 detects whether the power-off confirmation key signal is applied from the key input unit 100 during steps S30 and S40 (S50). It may be set to a power off key signal, a numeric key signal, a direction key signal, or the like.

As a result of the detection of step S 50, when the power-off confirmation key signal is applied from the key input unit 100, the system controller 200 determines that the power-off key signal applied from the key input unit 100 is generated by the user's intention in step S 20. If so, the power supply unit 600 is controlled to cut off the power supplied to the optical disc player 300.

Therefore, the power supply unit 700 stops the power supply provided to each component constituting the optical disc for the operation of the optical disc player under the control of the system control unit 200 (S 70).

On the other hand, if the power-off confirmation key signal is not applied from the key input unit 100 as a result of the detection at step S50, the system controller 200 stores the elapsed time and the count provided by the counter 400 at step S40. The confirmation key waiting time preset in the unit 500 is compared (S 60).

As a result of the comparison in step S60, if the elapsed time provided by the counter 400 is less than the confirmation key waiting time withdrawn from the storage unit 500, the system control unit 200 repeats the step S60 in step S30. In the optical disc player system including the key input unit 100, the OSD processing unit 700, the counter 500, the power supply unit 500, and the storage unit 500, the overall control of the system is performed. Repeat step 60.

On the other hand, as a result of comparing the step S 60, if the elapsed time provided by the counter 400 is greater than the confirmation key waiting time withdrawn from the storage unit 500, the system control unit 200 powers to perform the above-described step S 70 The supply unit 600 is controlled. That is, the system controller 200 controls the power supply unit 600 to cut off the power supplied to the optical disc player 300, and the power supply unit 600 controls the operation of the optical disc player under the control of the system control unit 200. In order to prevent this, the power supplied to each component constituting the optical disc player 300 is cut off.

Thus, the power supply of the optical disc player 300 is turned off (S70).

According to the present invention, after confirming that the power-off key signal provided from the key input unit 100 is due to the intention of the user, the power supply to the optical disc player 300 is controlled on / off, and the power is supplied by an error in key operation. By preventing this from being turned off, the time and power consumption for restarting the optical disc player can be reduced, thereby improving the performance and usability of the optical disc player.
