Abstract

PURPOSE: A method for displaying a real time is provided to always display a real time as a present time by enabling the present time to be corresponded to the real time of a teletext in case that there's a difference between the present time counted by a microcomputer and the real time of the teletext. CONSTITUTION: A present time counted by a microcomputer is compared with a real time of a teletext(S21). The present time of the microcomputer is reset to the real time of the teletext(S22). In case that the present time is corresponded to the real time, the present time of the microcomputer is displayed(S23). The microcomputer checks whether the real time of the teletext is transmitted from a selected channel(S24). In case that the real time isn't checked, the present time of the microcomputer is displayed(S25). In case that the real time is checked, the real time transmitted from the teletext is displayed(S26).

Description

표준시간 디스플레이방법{Real time display method}Standard time display method {Real time display method}

본 발명은 텔레텍스트 기능이 내장된 텔레비젼에서 현재시간을 디스플레이시키는 방법에 관한 것으로, 마이콤의 타이머블록에서 카운트되는 현재시간과 텔레텍스트를 통하여 송신되는 표준시간(Real time)을 비교하여 차이가 날 경우 현재시간을 텔레텍스트의 표준시간에 일치시켜 디스플레이시킴으로써 정확한 시간을 나타낼 수 있도록 하는 것이다.The present invention relates to a method for displaying the current time in a television with a teletext function. The present time counted in a timer block of a microcomputer is compared with a real time transmitted through teletext. By displaying the current time according to the teletext standard time, the correct time can be displayed.

텔레비젼에는 시간표시기능이 있어 한번 현재시간을 세팅시켜 줄 경우 계속하여 현재시간을 표시해주게 된다.The television has a time display function, so if you set the current time once, it will continue to display the current time.

그러나 시간카운트는 마이콤 내부의 타이머블록에 내장되어 있는 발진기의 발진주파수를 분주하여 카운트하게 되므로 발진기의 성능에 따라 시간이 지날수록 텔레비젼에서 표시하는 현재시간과 정확한 표준시간이 일치되지 않는 경우가 나타나게 된다.However, since the time count is divided by counting the oscillation frequency of the oscillator embedded in the timer block inside the microcomputer, the current time displayed on the TV and the exact standard time do not coincide with the oscillator performance. .

즉 정확한 현재시간을 세팅시켜 주었더라도 장시간이 경과할수록 표준시간과 텔레비젼에서 표시하는 현재시간과의 편차가 발생하게 되고 이에 따라 텔레비젼에 표시되는 현재시간을 확인하는 시청자에게 혼동을 주는 한편 텔레텍스트 기능 내장형 텔레비젼에서 텔레텍스트를 통하여 표준시간을 송신하는 채널에서는 문제를 야기시키게 된다.In other words, even if the correct current time is set, as the long time passes, the deviation between the standard time and the current time displayed on the TV occurs, which confuses the viewer who checks the current time displayed on the TV. In televisions that transmit standard time via teletext, this causes problems.

본 발명은 텔레텍스트 기능 내장형 텔레비젼에서,The present invention is directed to a teletext embedded television,

선택채널에서 텔레텍스트의 표준시간이 송신되는가를 체크하고,Check whether the standard time of teletext is transmitted in the selected channel,

마이콤에서 카운트되는 현재시간과 텔레텍스트의 표준시간을 비교하여 차이가 있을 경우 현재시간을 텔레텍스트의 표준시간에 일치시켜 표시시키며 텔레텍스트가 송신되지 않는 채널에서는 마이콤으로 카운트되는 현재시간을 그대로 표시시킴으로써 항시 표준시간을 현재시간으로 표시시킬 수 있도록 하는 것이다.By comparing the current time counted in the microcomputer and the standard time of teletext, if there is a difference, the current time is displayed according to the standard time of the teletext, and in the channel where the teletext is not transmitted, the current time counted by the microcomputer is displayed as it is. The standard time is always displayed in the current time.

이러한 본 발명은 텔레텍스트 기능 내장형 텔레비젼의 현재시간 표시방법에 있어서,The present invention is a method for displaying the current time of a television with a built-in teletext function,

선택채널에서 텔레텍스트의 표준시간이 송신되는 가를 체크하는 단계와,Checking whether a standard time of teletext is transmitted in a selected channel;

마이콤에서 카운트되는 현재시간과 텔레텍스트의 표준시간을 비교하는 비교단계와,A comparison step of comparing the current time counted in the microcomputer with the standard time of the teletext,

상기 비교단계에서 서로 일치할 경우는 그대로 현재시간을 표시시키고 일치하지 않는 경우는 마이콤의 현재시간을 텔레텍스트의 표준시간으로 세팅시키는 단계를 수행시킴으로써 이루어진다.In the comparison step, the current time is displayed as it is, and if it does not match, the current time of the microcomputer is set to the standard time of the teletext.

도 1 은 텔레비젼 회로도로써,1 is a television circuit diagram,

마이콤(100)은 리모콘 콘트롤신호를 인식하여 일반 텔레비젼모드 및 텔레텍스트 모드를 선택 제어하는 한편 내장된 타이머블록(110)에서 카운트된 현재시간을 필요에 따라 디스플레이되게 한다.The microcomputer 100 recognizes the remote control signal and selects and controls the general television mode and the teletext mode, and displays the current time counted in the built-in timer block 110 as needed.

타이머블록(110)은 내장된 발진기의 발진주파수를 분주카운트하여 사용자에 의해 세팅된 현재시간을 카운트하게 되며 마이콤(100)은 필요에 따라 타이머블록(110)에서 카운트된 현재시간을 디스플레이시키기 위한 OSD R.G.B 신호를 출력시키게 된다.The timer block 110 divides the oscillation frequency of the built-in oscillator to count the current time set by the user. Outputs an RGB signal.

마이콤(100)의 출력은 비데오프로세스(200)에서 비데오신호 처리되어진 후 CRT 디스플레이(300)에서 화면에 디스플레이되어진다.The output of the microcomputer 100 is processed on the video signal in the video process 200 and then displayed on the screen in the CRT display 300.

텔레텍스트블록(400)은 마이콤(100)의 제어에 의해 구동되며 텔레비젼의 수직블랭킹기간 중에 포함되어 송신되는 텔레텍스트신호를 수신 처리한 후 문자표시를 위한 텔레텍스트 R.G.B 신호를 비데오프로세스(200)에 인가시키게 된다.The teletext block 400 is driven by the control of the microcomputer 100 and receives and processes the teletext signal that is included and transmitted during the vertical blanking period of the television to the bidet process 200. Is authorized.

이때 텔레텍스트블록(400)은 텔레텍스트신호와 함께 방송국에서 송신되는 표준시간 데이타를 받아 비데오프로세스(200)에 함께 인가시킴으로써 시청자가 텔레텍스트화면 시청시는 표준시간을 확인할 수 있게 한다.At this time, the teletext block 400 receives the standard time data transmitted from the broadcasting station together with the teletext signal and applies the same to the bidet offline process 200 so that the viewer can check the standard time when viewing the teletext screen.

그러나 마이콤(100)에서 카운트되는 현재시간과 텔레텍스트블록(400)에서 검출한 표준시간과는 아무런 연관이 없어 마이콤(100)에서 카운트되는 현재시간과 텔레텍스트를 통해서 송신되는 표준시간이 서로 다른 경우 혼동을 초래하게 된다.However, since there is no correlation between the current time counted by the microcomputer 100 and the standard time detected by the teletext block 400, the current time counted by the microcomputer 100 differs from the standard time transmitted through the teletext. It will cause confusion.

따라서 본 발명은 텔레텍스트 기능 내장형 텔레비젼에서,Therefore, the present invention is directed to a teletext embedded television,

마이콤에서 카운트되는 현재시간과 텔레텍스트의 표준시간을 비교하여 차이가 있을 경우 현재시간을 텔레텍스트의 표준시간에 일치시켜 표시시키고, 텔레텍스트가 송신되지 않는 채널에서는 마이콤으로 카운트되는 현재시간을 표시시킴으로써 표준시간 또는 표준시간과 일치되는 현재시간을 확인할 수 있도록 한 것이다.By comparing the current time counted in micom with the standard time of teletext, if there is a difference, the current time matches the standard time of teletext and displays the current time counted by micom in the channel where teletext is not transmitted. It is to check the current time that matches standard time or standard time.

이러한 본 발명은 도 2 의 플로우챠트에 의거 상세히 설명한다.This invention is described in detail based on the flowchart of FIG.

먼저 마이콤에서 카운트되는 현재시간과 텔레텍스트의 표준시간을 비교한다.(S21)First, the current time counted in the microcomputer is compared with the standard time of the teletext (S21).

마이콤의 현재시간과 텔레텍스트의 표준시간에 서로 오차가 있는 것으로 판단되면 마이콤의 현재시간을 텔레텍스트의 표준시간에 맞추어 재세트시킨다.(S22)If it is determined that there is an error in the current time of the microcomputer and the standard time of the teletext, the current time of the microcomputer is reset according to the standard time of the teletext.

그러나 마이콤의 현재시간과 텔레텍스트의 표준시간이 일치할 경우는 그대로 마이콤의 현재시간을 디스플레이시킨다.(S23)However, if the current time of the microcomputer coincides with the standard time of the teletext, the current time of the microcomputer is displayed as it is (S23).

따라서 마이콤의 현재시간을 표준시간과 오차가 발생하지 않도록 디스플레이시킴으로써 시청자는 정확히 표준시간과 일치하는 현재시간의 확인이 가능하다.Therefore, by displaying the current time of the microcomputer so that the error does not occur with the standard time, the viewer can confirm the current time exactly match the standard time.

그리고 마이콤은 선택된 채널에서 텔레텍스트의 표준시간이 송신되는가를 체크하고(S24) 텔레텍스트의 표준시간이 체크되지 않을 경우(텔레텍스트 송신이 안되는 채널 선택시) 마이콤의 현재시간을 그대로 디스플레이시키고(S25) S24단계에서 텔레텍스트의 표준시간이 체크되는 경우(텔레텍스트가 송신되는 채널선택시) 텔레텍스트에서 송신된 표준시간을 디스플레이시킨다.(S26)Then, the microcomputer checks whether the standard time of the teletext is transmitted in the selected channel (S24), and if the standard time of the teletext is not checked (when selecting a channel that cannot transmit the teletext), the microcom displays the current time of the microcom as it is (S25). In step S24, when the standard time of the teletext is checked (when selecting a channel in which the teletext is transmitted), the standard time transmitted in the teletext is displayed.

따라서 텔레텍스트 송신이 되는지 안되는지에 관계없이 표준시간 또는 표준시간에 일치하는 현재시간의 디스플레이가 가능한 것이다.Therefore, whether the teletext transmission is performed or not, it is possible to display the current time corresponding to the standard time or the standard time.

본 발명은 마이콤의 현재시간과 텔레텍스트의 표준시간을 비교하여 차이가 있으면 텔레텍스트의 표준시간에 일치시키고, 텔레텍스트가 없으면 마이콤의 현재시간을 디스플레이시킴으로써 화면에 디스플레이되는 현재시간이 표준시간과 차이가 발생하는데 따른 혼동을 없앨 수 있는 것이다.The present invention compares the current time of the microcomputer with the standard time of the teletext and if there is a difference, matches the standard time of the teletext, and if there is no teletext, displays the current time of the microcomputer and the current time displayed on the screen is different from the standard time. Will eliminate the confusion that arises.
