Abstract
본 발명은 VCR에 있어서, 특히 VCR의 서보 PG(Pulse Generation)조정을 자동적으로 조정하는 자동 PG 조정장치에 관한 것으로, VCR의 PG조정을 자동으로 실현함으로써 라인 공정 개선 및 생산성을 향상시킬수 있고 데크주행계의 최적상태를 얻을수 있으며 테이프별로 정확한 PG조정을 이룰수 있는 VCR의 자동 PG 조정장치를 제공함에 그 목적이 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an automatic PG adjusting device that automatically adjusts the servo PG (Pulse Generation) adjustment of a VCR. In particular, the PG adjustment of the VCR can be automatically realized to improve line processes and improve productivity. Its purpose is to provide an automatic PG control device of VCR that can obtain the optimal state of the system and achieve accurate PG adjustment for each tape.
본 발명은 상기 목적을 달성하기 위해 RF 신호를 수신하여 색동기신호를 검출한 후 이를 출력하는 휘도 및 색신호처리부(10), 상기 휘도 및 색신호처리부(10)로부터 색동기신호를 수신하여 수직동기신호를 검출한후 이를 출력하는 한편 절환 포인트지점을 나타낸 데이터를 수신하여 PG M/M픽스(fix)를 하는 서보부(11), 상기 서보부(11)로 부터 수신한 수직동기신호를 기준펄스로 하여 F/F주기를 카운트함으로서 H/SW절환 포인트를 픽스하는 마이콤(12), H/SW가 절환되는 포인트를 계산하는 F/F발생부(13)로 구성함을 특징으로 한다.In order to achieve the above object, the present invention receives an RF signal, detects a color synchronization signal, and outputs a color synchronization signal from the luminance and color signal processing unit 10 and the luminance and color signal processing unit 10 to output the vertical synchronization signal. Detects and outputs it, while receiving the data indicating the switching point, the servo unit 11 performing the PG M / M fix, and the vertical synchronization signal received from the servo unit 11 as the reference pulse. By counting the F / F cycles, the microcomputer 12 fixes the H / SW switching point, and the F / F generating unit 13 calculates the point to which the H / SW is switched.
