Abstract
본 발명은 비디오 테이프의 재생시 양질의 화면을 제공하기 위한 방법에 관한 것으로서 특히 트랙킹값의 기준이 되는 컨트롤펄스(CTL Pulse)가 약하거나 없을 경우 트랙킹값의 결과에 의해 비디오 테이프상에 컨트롤펄스(CTL Pulse)를 기록하여 주는 방법에 관한 것으로 트랙킹 결과 트랙킹값을 비교하고 최종적인 트랙킹값을 저장하고 비디오 테이프상에 컨트롤펄스가 없는 경우에 컨트럴헤드에서 최종적인 트랙킹값에 따라서 컨트롤펄스를 복원하여 기록해주는 단계를 포함한다.The present invention relates to a method for providing a high-quality screen when playing a videotape. In particular, the present invention relates to a control pulse on a videotape as a result of a tracking value when the control pulse (CTL pulse), which is a reference value of a tracking value, is weak or absent. CTL Pulse) is a method of recording a tracking result. It compares the tracking result tracking value, saves the final tracking value, and restores the control pulse according to the final tracking value from the control head when there is no control pulse on the video tape. It includes the steps.
본 발명에 의하면, 비디오 테이프가 노화되어 컨트롤펄스가 약해졌거나 컨트롤펄스가 없는 경우에도 VTR에 의해 최상의 화질을 가지는 트랙킹값으로 컨트롤펄스를 기록해주기 때문에 항상 양질의 화면을 제공할 수 있다.According to the present invention, even when the video tape is aged and the control pulse is weakened or there is no control pulse, the control pulse is recorded with the tracking value having the best image quality by the VTR, so that a high-quality screen can be always provided.
