프로그램 체크키가 눌러지면 재생상태를 체크하여 재생상태이면 비디오 출력단을 제어하는 신호(S2CONT)를 '하이'로 출력한후 튜너/라인상태를 체크하는 과정과, 튜너 상태이면 그 상태의 채널 데이타를 기억하고 그채널을 일정시간동안(T1)보여 준다음 채널을 업시켜 업한 채널이 처음상태의 채널인지 체크하는 과정과, 업한 채널이 처음상태의 채널이 아니면 스킵으로 프리셋팅된 채널인지 체크하여 스킵으로 프리셋팅된 채널이 아니면 현재 채널을 일정시간 만큼 보여 주는 동작을 하고 업한 채널이 처음상태의 채널이면 비디오 신호 입력이 있는지를 체크하는 과정과, 비디오 신호 입력이 있으면 튜너/라인을 일정시간만큼 '로우'로 출력하여 라인 입력신호를 보여주고 비디오 신호 입력이 없으면 처음상태로 환원하는 과정과, 튜너/라인상태를 체크하여 라인상태이면 비디오 신호 입력이 있는지 체크하여 비디오 신호가 있으면 일정시간동안 입력을 디스플레이한후 튜너/라인 '하이'로 출력한후 그 채널을 기억하는 과정과, 기억된 채널을 일정시간동안 보여준 뒤 채널을 업하여 업한 채널이 처음의 채널인지 체크하는 과정과, 업한 채널이 처음이 채널이 아니면 스킵으로 셋팅된 채널인지 체크하여 스킵으로 셋팅된 채널이 아니면 다시 채널을 일정시간 보여주는 동작을 반복하고 업한 채널이 처음의 채널이면 튜너/라인을 '로우'로 출력하여 일정시간 만큼 튜너의 비디오 신호를 보여준 뒤 처음의 사태로 되돌아가는 과정을 포함하는 것을 특징으로하는 VCR의 프로그램 체크 방법.When the program check key is pressed, the playback status is checked. If the playback status is selected, the signal (S 2 CONT) that controls the video output terminal is output as 'high' and the tuner / line status is checked. Stores the data and shows the channel for a certain time (T 1 ) and then checks whether the uploaded channel is the initial channel by checking up the channel, and if the uploaded channel is not the initial channel or skipped channel. If the channel is not preset by checking and skipping, it shows the current channel for a certain time. If the up channel is the first channel, it checks whether there is a video signal input, and if there is a video signal input, the tuner / line is fixed. It outputs 'low' as time and shows the line input signal. If there is no video signal input, it returns to the initial state and changes the tuner / line state. If there is a video signal, check if there is a video signal input.If there is a video signal, display the input for a certain time, output it to the tuner / line 'high', store the channel and show the stored channel for a certain time. Repeat the process of checking whether the up channel is the first channel by turning the channel up, and checking whether the uploaded channel is the channel set to skip if it is not the first channel, and showing the channel again for a certain time if the channel is not set to skip. If the channel is the first channel, the program check method of the VCR comprising the step of outputting the tuner / line 'low' to show the video signal of the tuner for a predetermined time and then return to the first situation. 타이머 마이콤(IC1)과, 상기 타이머 마이콤에 부기되는 프로그램체크키(KEY1)와, 채널 프리셋팅 데이타를 기억하는 EA롬(IC3)와, 시스템을 콘트롤하는 시스템 콘트롤 마이콤(IC2)와, 상기 타이머 마이콤(IC1)에 의해 제어되며 안테나의 신호를 받는 튜너(1)와, 상기 타이머마이콤(IC1)에 의해 제어되며 튜너 비디오 신호를 출력하는 IF부(2)와, 튜너 비디오신호와 라인 비디오 신호를 입력으로 받아 타이머 마이콤(IC1)에 의해 제어되어 선택 출력하는 스위칭 IC(S1)와, 비디오 신호 입력을 받아동기 분리하는 동기 분리기(3)와, 상기 동기 분리기(3)의 출력을 받아 버퍼(5)를 거쳐 상기 타이머 마이콤(IC1)으로 비디오 신호를 인가하는 적분기(4)와, 테이프에서 재생된 신호를 재생비디오 신호로 출력하는 재생비디오 처리단(6)과, 상기 스위IC(S1)의 출력과 재생 비디오 처리단(6)의 출력을 입력으로 받아 비디오 신호를 출력하는 스위칭IC(S2)와, 상기 타이머 마이콤(IC1)으로부터 출력단콘트롤 신호(S2CONT)를 입력받아 동작하는 트랜지스터(Q1)와, 상기 트랜지스터(Q1)의 콜렉터 출력과 시스템 콘트롤 마이콤(IC2)의 재생신호를 입력으로 받아 상기 스위칭IC(S2)를 제어하는 앤드게이트(AND1)을 포함하여 구성된 것을 특징으로 하는 VCR의 프로그램 체크장치.A timer micom (IC 1 ), a program check key (KEY 1 ) appended to the timer micom, an EA ROM (IC 3 ) for storing channel presetting data, a system control micom (IC 2 ) for controlling the system, A tuner 1 controlled by the timer micom IC 1 and receiving an antenna signal, an IF unit 2 controlled by the timer microcom IC 1 and outputting a tuner video signal, and a tuner video signal; And a switching IC (S 1 ) which receives and receives a line video signal as an input and is controlled by a timer micom (IC 1 ), a synchronous separator (3) for synchronously separating and receiving a video signal input, and the synchronous separator (3). An integrator 4 for receiving a video signal and applying a video signal to the timer microcomputer IC 1 via a buffer 5, a reproduction video processing stage 6 for outputting a signal reproduced from a tape as a reproduction video signal; Output and Regeneration of the Switch IC (S 1 ) Switching IC (S 2 ) for receiving the output of the video processing stage 6 as an input and outputting a video signal, and transistor (Q 1 ) for receiving and operating the output terminal control signal (S 2 CONT) from the timer micom (IC 1 ).
