Abstract

본 발명은 VCR의 스틸제어회로에 관한 것으로, 외부로부터 소정의 명령을 입력받게 된 입력부(10)와, 소정의 입력값에 따라 모드를 플레이후 정지되어 다시 리버스플레이되도록 제어하도록 캠데이타를 바꾸게 된 로딩모터(12), 비디오테이프의 콘트롤트랙으로부터 콘트롤신호를 재생하게 된 콘트롤신호재생부(14), 상기 콘트롤 신호재생부(14)의 출력값에 의해 카운트를 증가시키게 된 카운터부(16) 및, 상기 입력부(10)를 통해 입력받은 스틸명령에 의해 상기 카운터부(16)를 리셋트함과 아울러 모드가 플레이에서 정지시킨 뒤 다시 리버스 플레이로 바꾸도록 제어하다가, 상기 카운터부(16)의 출력값이 소정치가 되었을 때 로딩모터(12)를 제어하여 정지화면을 재생하도록 된 제어부(18)로 구성, 시청자가 정지하고자 스틸키를 입력하게 되는 경우 신체적반응의 지연과 기계적 지연을 상쇄시켜 시청자가 보고자 하던 화면을 정확히 재생하도록 된 것이다.The present invention relates to a still control circuit of the VCR, and the input unit 10 receives a predetermined command from the outside, and changes the cam data so as to control the mode to stop and reverse play after playing the mode according to the predetermined input value. A control signal reproducing unit 14 which reproduces a control signal from the control motor of the loading motor 12, a video tape, a counter unit 16 which increases the count by an output value of the control signal reproducing unit 14, The counter unit 16 is reset by a still command received through the input unit 10, and the mode is controlled to stop the play and then change back to reverse play, and the output value of the counter unit 16 The controller 18 is configured to control the loading motor 12 to play back a still image when a predetermined value is reached, and when a viewer inputs a still key to stop, By offsetting the delay and the mechanical delay, the viewer wanted to play the screen exactly as he wanted to watch.

Description

Still Control Circuit of VCR

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명에 따른 VCR의 스틸제어회로의 일시시예를 도시한 블럭구성도, 제2도는 본 발명의 스틸제어 회로의 동작을 설명하기 위한 순서도이다.1 is a block diagram showing a temporary example of a steel control circuit of the VCR according to the present invention, and FIG. 2 is a flowchart for explaining the operation of the steel control circuit of the present invention.

Claims

The input unit 10 which receives a predetermined command from the outside, the loading motor 12 which changes the cam data so as to control the mode to be stopped and reversed again after playing the mode according to the predetermined input value, and the control track of the video tape. A control signal reproducing unit 14 for reproducing the control signal from the control unit, a counter unit 16 for increasing the count by the output value of the control signal reproducing unit 14, and a still command received through the input unit 10; The controller 16 resets the counter 16 and controls the mode to stop and reverse play, and then the loading motor 12 when the output value of the counter 16 reaches a predetermined value. A still control circuit of the VCR, comprising a control unit 18 configured to control and reproduce still images.
