콘트롤 펄스를 이용한 오토트랙킹 방법Auto tracking method using control pulse

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

제1도는 본 발명에 따른 시스템도,1 is a system diagram according to the present invention,

제2도는 본 발명에 따른 흐름도.2 is a flow chart in accordance with the present invention.

오토트랙킹 방법에 있어서, 오토트랙킹을 실행해야 되는지를 확인하고 실행해야 한다면 콘트롤펄스가 10개/초이상 인지를 확인하여 그렇지 않으면 모든 데이터를 초기화하는 데이터 초기화과정과, 상기 데이터 초기화 과정에서 콘트롤펄스 1-개/초이하이면 비디오 ENV의 크기를 읽은 다음 처음인가를 판단하고 처음일 경우 EMV크기를 기록하고 현데이타를 저장하며 이 데이터를 서보회로에 전송하는 현데이타 전송과정과, 상기 현데이타 전송과정에서 비디오 ENV가 처음이 아닐시 최종인가를 판단하여 최종이면 현재 트랙킹데이타를 서보회로에 전송하여 오토트랙킹을 완료했음을 표시하는 오토트랙킹 완료 표시 과정과, 상기 오토트랙킹 완료 표시 과정에서 비디오 ENV가 최종도 아닐시 현재의 ENV크기가 기존의 ENV보다 크면 현재의 ENV크기와 트랙킹데이타를 메모리하고 다음 트랙킹데이타를 서보회로에 전송하며 그렇지 않을 경우에는 즉시 다음 트랙킹데이타를 서보회로에 전송하는 트랙킹데이타 전송과정로 구성함을 특징으로 하는 콘트롤 펄스를 이용한 오토트랙킹 방법.In the auto tracking method, it is necessary to check whether or not auto tracking should be executed. If the control pulse is 10 or more seconds or more, the data initialization process of initializing all data and the control pulse 1 in the data initialization process. If it is less than / sec, it reads the video ENV size and judges whether it is the first time, and if it is the first time, the current data transmission process of recording the EMV size, storing the current data, and transmitting this data to the servo circuit, and the current data transmission process. If the video ENV is not the first time, it is judged whether it is the last time, and if it is the last time, the video tracking data is sent to the servo circuit to indicate that the auto tracking is completed, and the video ENV is not final in the auto tracking completion display process. If the current ENV size is greater than the existing ENV, the current ENV size and tracking day The memory and then transfer the data to the tracking servo circuit and, otherwise, the auto-tracking method using a control pulse to be characterized in that it consists of tracking the data transfer process of transferring immediately following the tracking data to the servo circuit. ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
