Abstract

The present invention relates to a time display method of the TV and VTR separately, so that the current time is precisely controlled by the microcomputer by the subclock oscillator, and when the current time reaches the right time, the current time is displayed on the screen for a predetermined time before and after the time. The display allows the user to be reminded of the passage of time.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a time display method of a TV and a VTR. More particularly, the present invention relates to a time display method of a TV and a VTR for displaying the current time to the outside for a predetermined time before and after the current time.

Conventionally, the current time is displayed only when there is a recall key input, and disappears after a predetermined time so that the current time can be checked if necessary. There was an inconvenience to reenter the current time if supplied.

Therefore, according to the above method, if there is no input of the recall key (marking) to confirm the current time, the current time is not displayed. If you want to know the time, you must turn on the recall key one by one. Even when the right time signal sounded, the correct time was not displayed, making it difficult to set the time, or if the power was removed, the current time had to be re-entered each time the power was turned on again. As a result, when a user is immersed in a TV or VTR, the user may forget the time.

Accordingly, an object of the present invention is to provide a time display method of a TV and a VTR for allowing a user to check the passage of time by displaying the current time for a predetermined time before and after each time.

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

FIG. 1 is a schematic block diagram according to a first embodiment of the present invention. In addition to the system clock oscillator (not shown) for driving the entire system, an oscillator (operated by a crystal oscillator (52.768 KHz) for use as a clock is separately provided. The present time stored in the memory 13 of the microcomputer 12 is controlled by the synchronization signal of 11). When the on-time display function switch SW1 is initially turned on, the present time is set to be before and after the right time whenever the current time reaches the right time. The OSD driver 14 is operated for a predetermined time so that the current time is displayed on the CRT (Cathode Ray Tube) 15 during the predetermined time.

FIG. 2 is a schematic block diagram according to a second embodiment of the present invention. If the first diagram is for visually displaying the present time, FIG. 2 is a right angle from the voice IC 16 under the control of the microcomputer 12. Before and after, the current time is output as sound to the speaker 17 for a predetermined time.

FIG. 3 is a flow chart for explaining the operation of FIG. 1, wherein the current time is continuously counted under the control of the microcomputer 12 receiving the clock frequency of the oscillation unit 11 (SW). _{When 1} ) is turned on (step 301), according to the program of the memory 13, the microcomputer 12 checks the minute unit of the current time (step 302) to determine whether the minute unit of the current time is 59 minutes ( Step 303), if the minute of the current time is 59 minutes or less (step 302), but if the minute of the current time is 59 minutes, the second of the current time is checked (step 304). It is determined whether is greater than or equal to a predetermined time (step 305), and if the second unit of the current time is longer than or equal to a predetermined time, the hour, minute and second of the current time are displayed on the CRT 15 from this time onwards. (Step 306).

However, if the second unit of the current time is within a certain time, the flow proceeds to step 304.

After a predetermined time has elapsed, the minute of the current time reaches 00 minutes, so that the minute of the current time is checked (step 307) to determine whether the minute is 00 minutes (step 308). If the minute unit is within 00 minutes, the process proceeds to step 307. If the minute unit of the current time is 00 minutes, the second unit of the current time is checked (step 309).

Then, it is determined whether the second unit of the current time is within a predetermined time (step 310), and if exceeded, the microcomputer 12 controls the OSD driver 14 to display the hour, minute, and second of the current time displayed on the CRT 15. (Step 311).

However, if the second unit is less than a predetermined time, the flow proceeds to step 309 above.

Thereafter, while the on-time display function switch SW1 is kept on, the process proceeds to step 302 to repeat the above operations.

The flowchart for FIG. 2 only shows the first and third views of the current time on the CRT 15 by operating the OSD driver 14 while FIG. 2 shows the voice from the voice IC 16 to the speaker 17. FIG. Since only the outputting step is divided, the flowchart of FIG. 2 is omitted.

As described above, according to the time display method of the present invention TV and VTR, the present time can be displayed or checked for a predetermined time before and after each time by the first key input, and the user can be warned of the time. There is an advantage to reminding us of the proper use of time and of other appointments and meetings.

Claims (1)

The microcomputer 12 receiving a predetermined predetermined clock frequency of the oscillator 11 outputs the current time of the memory 13 to the CRT 15 through the OSD driver 14 in units of hours, minutes, and seconds. And a time display method of the VTR; If the hourly time display function switch (SW ₁ ) is turned on, the minute of the current time is checked to determine if the minute of the current time is 59 minutes. If the second unit of the current time is less than or equal to a predetermined time, the step proceeds to the previous step, but if more than a predetermined time, the OSD driver 14 is operated by the control of the microcomputer 12, Displaying the current time according to the elapse of minutes and seconds, and controlling the voice IC 16 to output the current time to the speaker 17 as voice, and checking the minute unit of the current time in the case of 0 minutes or less. But if it is 0 minutes, it checks the seconds of the current time, and if the seconds of the current time is within a certain time, it goes to the previous stage, but if it exceeds the predetermined time, the microcomputer 12 The time of the TV and VTR characterized by the OSD driver 14 being controlled to perform the present time displayed on the CRT 15 by the hour, minute and second being erased and checking the minute unit of the present time which is the initial stage. How to display.
