Description

METHOD FOR TIME CORRECTION IN A TELEVISION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of setting a current time in a television. In particular, when the current time of a timer inside a microcomputer is corrected by a user's predetermined key operation, the operation time of the timer after setting is improved to improve a "second" unit. The present invention relates to a method of setting a current time in a television that enables the present time to be set more accurately without errors.

In general, in a television that receives a broadcast signal and enables viewing of video and audio, the television is turned on at a wake-up time set by the user for wake-up and sleep reservations, and the television is turned on at a bedtime set by the user. There is a reservation function to turn off.

The reservation function is performed by checking whether the reservation time (wake-up time, bedtime time) is reached by using a timer built in the microcomputer operating based on the constant power supply from the power supply unit supplying predetermined power to each component of the television. When the scheduled time comes, the power of the television is turned on / off by selectively blocking / supplying the predetermined power from the above-described power supply for operating each component, or in particular, selectively controlling the operation of the CRT with the largest power consumption. The microcomputer operates the high voltage circuit supplying the high voltage DC required for the CRT by stepping up and rectifying the pulse voltage generated during the horizontal blanking period in the horizontal output circuit. Selectively control the horizontal output circuit to generate or not generate pulse voltage Its function is performed.

On the other hand, such a reservation function helps the user wake up by starting the broadcasting of the television in the morning through the user's wake-up time setting, and by setting the sleep time, the user's time to go to sleep stops This is a very useful feature that allows the user to recognize the bedtime or to automatically turn off the TV when the user is asleep.

1 is a schematic block diagram of a general television, including a key input unit 10, a microcomputer 20, a timer 30, a tuner unit 40, a video / audio signal processing unit 50, an OSD unit 60, And a monitor CRT 70, a speaker 80, and a power supply 90.

In this configuration, the key input unit 10 is provided with a plurality of keys for performing various operations of the television outputs a key signal corresponding to the user's key operation to the microcomputer 20, the microcomputer 20 is the key input unit Each component is controlled on the basis of the key signal from (10) to control the overall operation of the television. The timer 30 is reset based on a predetermined power source from the power supply unit 90 described later, and is based on the predetermined oscillator. To keep the current time.

The tuner 40 receives a broadcast signal received through a channel selected under the control of the microcomputer 20, and the video / audio signal processor 50 demodulates / decodes a broadcast signal applied from the tuner 40. It detects and separates the video signal and the audio signal, and processes the separated video signal into a displayable signal and outputs it to the OSD unit 60. The separated audio signal is processed into a signal that can be output and output to the speaker 80. The OSD 60 synthesizes the video signal applied from the video / audio signal processor 50 and the text signal corresponding to the control of the microcomputer 20 and outputs the synthesized text signal to the monitor 70.

In addition, the power supply unit 90 supplies predetermined power for the operation of each component described above.

When performing the reservation function in the television having the above-described configuration, the current time maintained based on the driving of the timer 30 is used, but the current time of the timer 30 has a possibility that an error occurs when time passes. When these errors accumulate, the current time is not accurate.

Therefore, since the reservation function in the above-described television can be properly performed only when the current time of the timer inside the television is accurate, the current time of such television is conventionally cut off when the main power supply of the television is cut off. When this is initialized or when the current time set in the user's confirmation by the user is different from the actual current time, the user has to correct the setting by a predetermined key operation.

On the other hand, in a broadcasting system providing an extended data service (EDS), for example, KBPS (Korea Broadcasting Program System) is a data for broadcasting programs and scheduled recording on a broadcast signal, for example, a channel, a broadcast category (for example, , News, drama, sports, etc.), broadcast start / end time, viewing grade, and standard time data are converted into digital signals and inserted into any horizontal line during the vertical blanking interval (VBI). The signal is decoded by the KBPS decoder on the image receiving device side to perform a broadcast program reservation recording function.

Therefore, in the television equipped with the KBPS broadcasting system providing the above-described EDS and equipped with the KBPS decoder, it is possible to automatically correct the time of the television by decoding standard time data from the above-mentioned data.

In other words, the standard time data is coded into a predetermined digit (for example, 8 digits) including "hours", "minutes", and "seconds" and inserted into any horizontal line within the vertical blanking period of the video signal. In a television, a standard signal is extracted by decoding a sync signal from a broadcast signal received from a tuner, extracting and decoding standard time data inserted into an arbitrary horizontal line within a vertical blanking period of the separated sync signal, and using the decoded standard time data. The current time of the timer inside the microcomputer is automatically corrected.

However, poor reception of a broadcast signal in the process of extracting and decoding all data (8 digits) of "hours", "minutes", and "seconds" of standard time data inserted in any horizontal line within the vertical blanking period described above. Based on the sensitivity, there is a high probability of error, and when such an error occurs, an error of "hours" or "minutes" causes a large error in the current time, and thus the TV has an erroneous current time. If the television does not receive the time correction function or the standard current time data described above is not received, the user must set the current time of the television directly.

Meanwhile, when a predetermined key provided in the key input unit 10 is manipulated to set a user at the current time, a predetermined OSD screen for setting a time as shown in FIG. 2 is displayed.

At this time, the user operates the predetermined direction key and selection key provided in the key input unit 10 to set the current clock in the order of hours, minutes, and seconds, and sets the automatic ON-TIME and After inputting the auto-off time in order, a channel PR.NO for auto-on-time tuning of the television is input.

As a result, only after inputting a channel for automatic on-time tuning of the TV, the user exits the current time setting menu. At this time, the microcomputer 20 corrects the internal timer with the time input in the current time setting menu to maintain the current time. .

However, as described above, it takes a considerable time to set the TV's auto on time, TV's auto off time, auto on time sync channel, etc. in addition to the current time on the current time setting menu. There was a problem that the delay time it takes to eventually occur as an error.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object thereof is to input a setting item other than the current time on a current time setting menu for setting a value of a timer for maintaining a current time inside a microcomputer on a television. In order to consider the time, it is detected that the entry of the item of the current time is completed on the current time setting menu, and when the entry of the item of the current time is completed, the internal timer is corrected and set to the input current time immediately, and the current time is more accurately It is to provide a current time setting method in a television to be set.

The present time setting method in the television according to the present invention is a method of correcting and setting the present time for various reservation functions in a television, and if there is a predetermined key input for the present time setting, the present time, the automatic driving time, and the automatic Displaying an on-screen display (OSD) menu including a drive off time and a tuning channel, temporarily storing a current time based on a key input applied when a current time item is selected based on a predetermined key input, and inputting a current time If the predetermined key input for moving the item is terminated, the method includes a step of correcting, setting and starting the current time of the internal timer using the current time input up to now.

The above objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The television employed in accordance with the present invention is a general television of FIG. 1, which is briefly described once again, and includes a plurality of keys for operating a television, and a key input unit for outputting a key signal corresponding to a user's key operation. (10), and controls the overall operation of the television based on the key signal from the key input unit 10, in particular, when a predetermined key signal for setting the current time from the key input unit 10 is applied to the OSD unit 60 Display the OSD menu screen of FIG. 2 for setting the current time and various items by controlling, and determine whether the input of the current time item is terminated based on a predetermined key signal from the key input unit 10, and then the current time item. When the input is completed, the microcomputer 20 for setting and correcting the current time maintained by the internal timer 30 by using the input current time, the tuner unit 40, and the video / audio scene The OSD unit which forms a predetermined character screen corresponding to the control of the processing unit 50 and the microcomputer 20, synthesizes the blue back signal or the video signal applied from the video / audio signal processing unit 50, and outputs it to the monitor 70. It consists of 60.

Next, the present time setting process according to the preferred embodiment of the present invention in a television having the above-described configuration will be described in detail with reference to the flowchart of FIG.

First, when the television is switched to the active mode in which the television is powered on based on the power on / off key signal from the key input unit 10 (step 300), the microcomputer 20 sets the current time from the key input unit 10 to set the current time. It is determined whether a predetermined key signal is applied (step 302).

At this time, if a predetermined key signal for setting the current time is applied from the key input unit 10, the microcomputer 20 controls the OSD unit 60, as shown in Figure 2, the current time (CLOCK), automatic driving A predetermined OSD menu screen for setting the ON-TIME, the OFF-TIME and the tuning channel PR.NO is displayed (step 304).

Here, the current time represents the current time held by the timer 30 of the television, and the auto drive on time is for reserving the time when the television is automatically powered on, and the auto drive off time is for the television to be automatically operated late at night. Is a time to reserve the power to be turned off, and the tuning channel indicates the channel (program number in Europe) to which the television is automatically tuned on.

At this time, the user can input a desired time and channel to each item by performing a predetermined key operation provided in the key input unit 10 while viewing the OSD menu screen.

In detail, the user typically moves each item by manipulating the up, down, left and right arrow keys provided in the key input unit 10, and selects an item to be input based on the key operation, and then enters the key input unit 10. The time or channel is input using the provided numeric keys or the up, down, left, and right arrow keys. When the input is finished for one item as described above, the user moves to the other item by operating the up, down, left, and right arrow keys described above, and repeats this process to input the desired time and channel to all items.

Therefore, the microcomputer 20 monitors the key signal from the key input unit 10, and first determines whether the current time item is selected (step 306).

At this time, if the current time item is not selected and other items are selected, input setting is performed for the other selected item (step 308), and the process proceeds to step 306 described above to continuously determine whether the current time item is selected. .

On the other hand, if the current time item is selected in the above step 306, the microcomputer 20 continues to monitor the key signal from the key input section 10 to temporarily store the current time input (step 310).

At this time, the user inputs the actual current time in units of "hours", "minutes", and "seconds." When the input of the current time is completed, the user presses the up, down, left, or right arrow keys of the key input unit 10 to move to another item. Will be manipulated.

Therefore, the microcomputer 20 continuously monitors the key signal from the key input unit 10 to determine whether the entry of the item at the present time is finished and another item is selected (step 312).

In this case, if the input to another item does not proceed, it is determined that the current time input step of the above-described step 310 is not completed, and the process proceeds to the above-described 310 to temporarily store the current time.

On the contrary, when it is monitored to move to another item in the above-described step 312, the microcomputer 20 loads the temporarily stored current time input to the internal timer 30 based on the user's key operation to correct the current time. Hold (step 314).

As such, when the current time item is left out, the internal timer 30 is corrected using the current time input immediately, and the timer 30 is continuously started to be operated to prevent the minimum error in the setting of the current time. will be.

On the other hand, it will be understood by those skilled in the art that various changes and modifications can be made without departing from the spirit of the present invention.

As described above, according to the present invention, when the user displays a predetermined OSD menu screen including setting items other than the current time on the television and sets the current time directly, the current time item is selected and based on key operation by the user. When the current time is input and moved to another item, the current time is immediately applied to the internal timer to start operation at the current time, thereby minimizing an error occurring when the current time is set.
