Automatic On-Time Setting Method for TV

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for automatically setting on-time for a television, and in particular, a method for setting an on-time using previous on-time data when the on-time is not reset, and automatically turning off the television after a predetermined time has elapsed. It is about.

In general, the TV is automatically turned on when the set time is reached, and after the set time has passed or after a certain time has elapsed, the viewer has not inadvertently shut down the TV before going to bed. Has an "off-time function" that powers off. In general, the on-time function is commonly used as a "wake-up" or "morning call" function to occur at a predetermined time, and the off-time function is commonly used as a "sleep" function. In addition, the television has an auto-off function when there is no signal, so that the broadcasting station automatically turns off the power after a predetermined time from the end of the broadcast in the predetermined time zone to prevent unnecessary power consumption.

However, the data set at the time of setting the on time is inconvenient to be updated every time after the on time function is executed, and the on time function as a "morning call" function when the on time is not set due to user carelessness. There was a problem that could not be done properly.

Accordingly, an object of the present invention is to provide a method for resetting the on time using previous on time data when the on time is not reset, and automatically turning off the television after a predetermined time has elapsed. To provide.

In order to achieve the above object, the on-time automatic setting method according to the present invention in a television

Determining whether the user resets the on time;

Setting an on time using previous on time data when the on time is not reset in the determining step;

Setting a locking time by a user;

Counting a clock after the television is off and turning on the television when the on time set in the on time setting step is reached;

Counting a clock after the television is turned on, and turning off the television when the locking time set in the locking time setting step has elapsed.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

FIG. 1 is a block diagram illustrating a general television having an on-time function, wherein an antenna ANT for receiving radio waves from the air and a radio signal of a selected channel among radio signals received from the antenna ANT are inputted as intermediate frequency signals. The output of the tuner 101, the intermediate frequency amplifier (IF AMP) 103 that amplifies the intermediate frequency signal output from the tuner 101, and the output of the intermediate frequency amplifier 103 detects synchronization by detecting only the image intermediate frequency signal. And an output of the CRT driver 107 and the intermediate frequency amplifier 103 which display the image processing unit 105 for converting the composite image signal into an RGB signal, and display the output of the image processing unit 105 on the cathode ray tube (CRT). The audio processing unit 109 detects only the audio intermediate frequency signal and processes the signal by the amplifier 111 and the control unit 119 which amplify the output of the audio processing unit 109 to drive the speaker SP. Power supply A remote control transmitter for inputting and demodulating the wireless signal of the remote controller transmitter (115), a remote control transmitter (115) for inputting various commands for manipulating a television including an on-time time. 117) If the on-time setting key is input, the OSD processing unit 121 controls the on-time, and when the on-time is set, the power supply 113 of the television is turned on, and the image processing unit 105 and the audio processing unit 109 are set. When the on-time is set through the control unit 119, and the remote control transmitter 115 to control the on-screen display (On Screen Display (hereinafter referred to as OSD)) is composed of an OSD processing unit 121.

2 is a flowchart illustrating a method for automatically setting an on-time according to the present invention, and determining whether the on-time is reset when the television power is on, and resetting if the on-time is not reset (steps 201 to 207). Step) counting the clock after the television is turned off and turning on the television when the on time is reached (steps 209 to 215), and locking time set by counting the clock after the television is turned on If this has passed, the step of turning off the power of the television (steps 217 to 221) is constituted.

Then, look at the operation of the present invention configured as described above are as follows.

As described above, the television has an on-time function and an off-time function. For this function, the control unit 119 of the television has a timer therein and controls the OSD processing unit 121 to display channels and times. That is, the controller 119 may display a current time by embedding a timer, and compare the set time with the current time to control the power supply 113 when the on time is on, and control the power supply 113 when it is off time. To turn the power off.

For this on-time function, first, a process of setting the on-time when the television is turned on (step 201) will be described.

First, press the On Time setting key on the remote control.

Second, when the on-screen setting message appears on the screen by pressing the on-time setting key, enter the hour, minute, channel, and volume according to the instructions. At this time, the on-time function may be set only on a specific date by inputting a date, or may be set to be on-time at a predetermined time every day. In the present invention, the locking time can be set separately when the on time is set.

Third, the on-time setting is completed by inputting an on-time setting key or an enter key.

However, in step 203, it is determined whether the on time is reset as described above, and if the on time is reset, the television is operated normally (step 205). If not, the previous time stored in the memory of the controller 119 is not stored. The on time is reset using the on time data (step 207). In this case, the locking time may be set at the same time.

After the on time is reset as described above, when the power is turned off by the off time function or the user turns off the power (step 209), the controller 119 continuously counts the clock using a timer (step 211). Always comparing whether the current time is equal to the on-time time (step 213), and when the on-time is reached, the power supply 113 is controlled to turn on the power (step 215). If the on time has not elapsed, the process returns to step 211.

When the power is turned on, the tuner 101, the intermediate frequency amplifier 103, the image processing unit 105, the audio processing unit 109, and the like operate normally to output the broadcast video signal of the received channel on the CRT, The audio signal is output to the speaker SP.

After that, the controller 119 counts the clock using a continuous timer (step 217) and compares whether the set locking time has elapsed when the on time is set (step 219). (Step 221) If the locking time has not elapsed, the process returns to step 217.

On the other hand, the above detailed description is intended to describe particular embodiments presented herein and is not intended to limit the present invention. Those skilled in the art may make various changes and modifications within the technical spirit of the present invention with reference to the above detailed description and drawings.

As described above, according to the on-time automatic setting method according to the present invention for a television, if the on-time is not reset after the on-time function is once executed, the on-time is reset using the previous on-time data, By automatically turning off the television after a predetermined time has elapsed, the on-time function can be used more effectively as a morning call function.
