BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television receiver, and in particular, when a user sets a sleep mode switching function in response to a specific broadcast program, the program is timed based on a KBPS (Korea Broadcast Program Service) data signal transmitted from a broadcasting station. The present invention relates to a television receiver having a sleep mode switching function by a program reservation that is automatically switched to the sleep mode.

Among currently available television receivers (hereinafter referred to as TV receivers) or VCRs, the user sets a predetermined time in advance so that the power is automatically turned on or off when the corresponding time is reached. In addition, there are a number of products equipped with a reservation function that automatically executes recording of a program that is broadcasted at a predetermined time or at a scheduled time. FIG. 1 schematically shows an internal configuration of a general TV receiver having an on / off timer function. The block diagram shown.

In FIG. 1, reference numeral 1 denotes an antenna for receiving an air wave broadcast, 2 denotes a tuner for broadcasting station, and 3 denotes an IF amplifier for amplifying an intermediate frequency (IF) signal output from the tuner 2. .

Further, reference numeral 4 denotes P / S separation, for example, consisting of a surface acoustic wave filter (SAWFILTER) for separating the IF signal output from the IF amplifier 3 into an image intermediate frequency signal PIF and an audio intermediate frequency signal SIF. 5 is a voice detector for detecting a voice signal from the voice intermediate frequency signal SIF output from the P / S separation unit 4, and 6 is a voice signal output from the voice detector 5 The voice processor 7 is an audio amplifier which amplifies the voice signal processed by the voice processor 6 to a predetermined level and outputs it to the speaker.

On the other hand, reference numeral 8 is an image detector for detecting an image signal from an image intermediate frequency signal (PIF) separated and output from the P / S separator 4, and 9 is an image output from the image detector 8 An image processor which processes signals and outputs different R (Red), G (Green), B (Blue), and luminance signals (Y), and 10 denotes R, G, B, and luminance from the image processor (9). A signal Y is mixed with OSD pattern data from the first OSD generator 14, which will be described later, and output to the CRT driver (not shown).

Reference numeral 11 denotes a remote control unit for inputting an ON or OFF time of the TV receiver or other TV operation signals, and 12 denotes a receiving unit for receiving an infrared signal transmitted from the remote control unit 11. 13 is a control unit for controlling the overall device according to the operation signal received through the receiving unit 12, 14 is a predetermined OSD pattern data for guiding the user's time data input or operation signal input through the remote control device (11) The first OSD generating device for generating a.

Reference numeral 15 denotes a power plug, and 16 denotes a main power supply configured by, for example, a switching mode power supply (SMPS) for supplying operating power to the entire apparatus, and RY is supplied from the power plug 15 to the main power supply 16. 17 is a relay driver which drives the relay RY according to a predetermined control signal from the controller 13.

Reference numeral 18 denotes a memory for storing time data input by the user using the remote controller 11, 19 is a timer for generating predetermined time data, and 20 is time data generated by the timer 19. A time determination unit for determining the ON or OFF time of the TV based on the time data stored in the memory 18, 21 is a standby power for the ON timer function or the initial operation of the TV receiver. Standby power supply unit.

That is, in the above configuration, when the user reserves the on / off time of the TV using the remote controller 11, the controller 13 controls the first OSD generator 14 to input the user's time. In the meantime, the time data input by the user is stored in the memory 18.

Then, once the on / off time is stored in the memory 18 through the above process, the time determiner 20 counts the time data stored in the memory 18 and the time counted by the timer 19. The controller 13 determines whether the data match and outputs a determination signal accordingly. The controller 13 controls the relay driver 17 to drive the relay RY based on the determination signal applied from the time determiner 20. By turning on or off, the TV receiver is turned on / off at that time.

Therefore, the conventional TV receiver having the above-described configuration allows the viewer to arbitrarily set the on or off time, so that the TV receiver can be used as a convenient tool for living such as an alarm device.

However, for the on / off timer function as described above, a configuration such as a timer 17, a memory 18, a time determiner 20, and the like must be provided inside the TV receiver. In this case, there was an unreasonable element that the TV receiver itself had to be exchanged in order to receive the reservation driving function.

On the other hand, in recent years, the G-code type reservation recording, which makes reservation recording on the device itself based on the time data set by the user, has various problems. Therefore, broadcasting stations can broadcast information about each broadcasting program. The Korean Broadcast Program Service (KBPS) method has been developed to provide general information about program start and end time or program contents by transmitting it on a specific frequency band and transmitting it to the TV receiver. As described above, the present invention was created in view of the above circumstances, and KBPS (Korea Broadcast Program Service) data transmitted from a broadcasting station when a user sets a sleep mode switching function in response to a specific broadcast program Based on the signal, the system automatically enters the sleep mode at the end of the program. The purpose of the present invention is to provide a television receiver with a sleep mode switching function by program reservation.

In order to realize the above object, a television receiver having a power-on function by program reservation according to the present invention intercepts an image detector which detects only an image signal among broadcast signals received by an antenna, and an operating power supply of the TV as a whole. A television receiver having a power interrupter and a controller for controlling the overall apparatus; A timer for counting a predetermined time contracted according to a predetermined control signal from the controller, a reserved program selection unit for input setting program data for a specific program to be reserved by the user, and program data selected by the reserved program selection unit A program setting unit for storing the data; a KBPS decoder unit for detecting KBPS code data from the image signal output from the image detector; and a KBPS code detected at the KBPS decoder unit; And a program determiner for outputting a detection signal of a first level in the same case, wherein the control unit controls the timer according to the level of the sensed signal output from the program determiner and based on the count value of the timer. Characterized in that the power interruption on / off control Shall be.

That is, according to the present invention having the above-described configuration, even if the TV does not have a separate on / off function, the operation state of the TV is automatically switched to the sleep mode based on the end time of the broadcasting program set by the user in advance. It becomes possible.

Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention.

2 is a view showing the main configuration of a television receiver having a sleep mode switching function by program reservation according to an embodiment of the present invention, the same components for performing the same function as the component shown in FIG. Reference numerals will be omitted and detailed description thereof will be omitted.

In FIG. 2, reference numeral 111 denotes a remote control device additionally provided with a predetermined function key (not shown), and 112 denotes a receiving unit which receives a far infrared ray signal transmitted from the remote control device 111 and converts it into an electrical signal. , 113 is a control unit for controlling the entire apparatus according to the contracted code signal output from the receiver 112, 200 is a predetermined time (e.g. 30 minutes) contracted according to a predetermined control signal output from the control unit 113 Is a timer (TIMER).

In addition, reference numeral 100 is a program setting unit for storing code data for a corresponding program set when a user reserves a program to watch through a function key (not shown) installed in the remote control device 111, and 101 denotes the above. A KBPS decoder unit for detecting a KBPS code signal from an image signal output from the image detector 8 and outputting code data for a unique ID and a broadcast start time of a currently viewed program based on the KBPS decoder unit, 102 is the KBPS decoder unit. The code determination unit outputs a predetermined detection signal to the control unit 113 when the code data output from the device 101 is retrieved and the same code data as the code data stored in the program setting unit 100 is detected.

Next, the operation of the apparatus according to the present invention having the above-described configuration will be described.

For the program reservation function according to the present invention, the user presets a program he wants to watch through a predetermined function key (not shown) installed in the remote control device 111, and sets a sleep function. Since it means that the user is going to bed soon, it is possible to use a specific KBPS code, such as the end time of the program currently being watched or the unique ID of the national anthem transmitted immediately before the end of the regular broadcast.

On the other hand, program data input through the remote control device 111 is stored in the program setting unit 100, the control unit 113 drives the tuner 2 to control the KBPS code for all channels currently being broadcasted Run the search.

The KBPS code signal for each channel retrieved by the above process is detected by the KBPS decoder 101 so that the unique ID for each program and the code data for the broadcast start time are applied to the program determination unit 102.

The program determining unit 102 compares the code data applied from the KBPS decoder 101 with the data stored in the program setting unit 100 and transmits a predetermined detection signal to the control unit 113 when the same code is applied. As a result, the controller 113 switches the operation mode to the sleep mode based on this, and simultaneously drives the timer 200 to count a predetermined time (for example, 30 minutes).

When the timer 200 completes the counting operation for the contracted time 30 minutes, the controller 113 checks this and turns on the power supply side relay RY and at the same time, the timer 200. Will be reset.

That is, according to the above embodiment, when the user sets the sleep mode switching function in response to a specific broadcast program, the user enters the sleep mode according to the end time of the program based on the KBPS (Korea Broadcast Program Service) data signal transmitted from the broadcasting station. By automatically switching, even in the case of a TV that does not have a separate on / off timer function, the above-described sleep mode automatic switching function can be easily provided.

The present invention is not limited to the above-described embodiments, and can be variously implemented without departing from the technical gist of the present invention. For example, the sleep mode setting time can be freely changed by the user by adjusting the count value of the timer. It can also be configured.
