Real Time Clock (hereinafter, abbreviated as RTC) block 40, tuner micom 50, hard disk drive (HDD) 60, tuner 70, analog digital converter (Analog Digital) Convertor: hereafter abbreviated as ADC 80, a digital analog converter (hereinafter abbreviated as DAC) 90, and a display device 100.

The power supply unit 10 provides an AC voltage (for example, 220V), which is a commercial power supply, to the transformer 20.

The transformer 20 normally maintains the contact in the off state, and accordingly to the contact on signal provided by the tuner microcomputer 50, the contact is in an off state, that is, the power supply unit 10 is attached. The AC voltage provided by the converter is converted into an arbitrary DC voltage and provided to the main CPU 30.

After the main CPU 30 is operated by the DC voltage provided from the transformer 20, the main CPU 30 controls to store the reserved recording program start time information input by the user in the hard disk drive (HDD) 60, and controls the ADC ( The reserved recording information according to the reserved recording program start time information provided from 80 is controlled to be stored in the hard disk drive (HDD) 60.

In addition, the main CPU 30 reads the start time information to be recently reserved from the reserved recording program start time information stored in the HDD 60 and provides the RTC block 40 to the RTC block 40 and the recently reserved time stored in the HDD 60. The reserved recording information according to the start time information is read and provided to the DAC 90.

Here, the HDD 60 stores the reserved recording program start time information in a sorted form under the control of the main CPU 30, and also the reserved recording information according to the reserved recording program start time information under the control of the main CPU 30. Save it.

The RTC block 40 is linked to the backup battery by itself and is operated by the backup battery to receive the start time information to be recently reserved by the main CPU 30, and to compare the internal timer to determine the start time information to be recently reserved. When reaching, the wake-up operation signal is provided to the tuner microcomputer 50.

The tuner micom 50 provides a contact on signal for attaching a contact in the transformer 20 to the transformer 20 according to the wake-up operation signal provided by the RTC block 40, and also provides the tuner micom 50. The channel signal is received from the tuner 70 and provided to the ADC 80.

Here, the tuner 70 provides a channel signal input through an antenna (not shown) to the tuner microcomputer 50.

The ADC 80 receives the channel signal from the tuner microcomputer 50, converts the channel signal into a digital signal, and provides the same to the main CPU 30. The DAC 90 may be recently read out according to the control of the main CPU 30. The reservation recording information according to the start time information is converted into an analog signal and provided to the display apparatus 100.

The display apparatus 100 displays the reserved recording information according to the recently scheduled start time information converted by the DAC 90 for the user to watch.

Based on the above-described configuration, the operation of the power save device of the FV system according to the present invention will be described in more detail.

First, a user inputs reservation recording program start time information to the main CPU 30 using the FB system.

When the main CPU 30 controls to store the reserved recording program start time information input by the user in the hard disk drive (HDD) 60, the main CPU 30 is automatically sorted and the reserved recording program start time information is stored in the HDD 60. do. Thereafter, the main CPU 30 reads start time information to be recently reserved from the reserved recording program start time information stored in the HDD 60 and provides it to the RTC block 40.

After that, when the user turns off the power, the RTC block 40 automatically starts to be scheduled in the main CPU 30 by being operated by the backup battery while being linked to the backup battery. When received and compared with the internal timer to determine the latest scheduled start time information and provides a wake-up operation signal to the tuner micom 50.

The tuner microcomputer 50 provides the transformer 20 with a contact on signal for attaching a contact in the transformer 20 according to the wake-up operation signal provided by the RTC block 40.

Then, the transformer 20 normally maintains the contact in the off state and attaches the contact according to the contact ON signal provided from the tuner microcomputer 50 to randomly select an AC voltage provided from the power supply unit 10. The DC voltage is converted into DC voltage and provided to the main CPU 30.

After the main CPU 30 is operated by the DC voltage provided from the transformer 20, the reserved recording information according to the reserved recording program start time information is transmitted through the tuner 70, the tuner microcomputer 50, and the ADC 80. It is provided and stored in the hard disk drive (HDD) 60 and provided to the DAC (90).

The DAC 90 converts the reservation recording information according to the recently scheduled start time information read out under the control of the main CPU 30 into an analog signal and provides it to the display apparatus 100.

The display apparatus 100 displays the reserved recording information according to the recently scheduled start time information converted by the DAC 90 for the user to watch.

On the other hand, after the scheduled recording function is completed, the main CPU 30 searches the HDD 60, reads the start time information of the next most recently scheduled recording program, provides it to the RTC block 40, and simultaneously turns off the power. OFF) provides status information to the RTC block 40.

The RTC block 40 provides the tuner microcomputer 50 with the power OFF state information provided from the main CPU 30, and then continuously monitors its own timer while the next most recent time in the main CPU 30. When the start time information to be reserved is received and compared with the internal timer, the wake-up operation signal is provided to the tuner microcomputer 50 when the latest start time information is reached.

The tuner microcomputer 50 provides the transformer 20 with a contact off signal for causing a contact in the transformer 20 to fall off according to power off state information provided from the RTC block 40. In addition, the tuner microcomputer 50 provides the transformer 20 with a contact-on signal for attaching a contact in the transformer 20 in response to the wake-up operation signal provided from the RTC block 40.

In this way, as the main CPU 30 performs the reservation recording function while repeatedly performing the above-described process while searching and determining the HDD 60, unnecessary power generated by the power supply unit 10 is always applied to the main CPU 30. The power can be prevented in advance.

Therefore, when the user reserves a program using the PVR system and turns off the power, when the reservation time is reached, power is automatically supplied to perform a scheduled recording function, thereby providing an existing PVR system. As power is always supplied, an unnecessary energy consumption generated by performing the scheduled recording function can be prevented.
