Abstract

본 발명은 비디오 씨. 디 플레이어에 사용되는 비디오 신호 선택 처리장치에 관한 것으로, 비디오 씨. 디에 기록된 데이타를 판독하여 상기 비디오 씨. 디의 기록방식이 NTSC 방식인지 또는 PAL 방식인지를 판별하고, 이에따른 제어신호를 발생하는 마이컴(80)과, 3.58㎒의 칼라 서브 캐리어(color sub-carrier) 신호를 발생하는 3.58㎒ 오실레이터(85)와, 4.43㎒의 칼라 서브 캐리어 신호를 발생하는 4.43㎒ 오실레이터(90)와, 마이컴(80)의 제어에 따라 스위칭되어 3.58㎒의 서브 캐리어 신호 또는 4.43㎒의 서브 캐리어 신호를 패스(pass)시키는 스위칭부(100)와, 마이컴(80)의 제어에 따라 수평 및 수직 동기 신호를 선택적으로 발생하는 동기 신호 발생부(120)와, 3.58㎒의 서브 캐리어 신호 또는 4.43㎒의 서브 캐리어 신호 수평 및 수직 동기 신호에 따라, 아나로그 신호로 변환 처리되어 제공되는 비디오 신호를 RGB 신호로 변환하여 출력하는 RGB 엔코더(140)를 포함하고 구성되어, 비디오 디스크 재생시 그 디스크가 NTSC 방식으로 기록되었는지 또는 PAL 방식으로 기록되었는지를 판별하여 각각의 경우에 있어 적절히 비디오 신호를 처리함으로써, 사용자에 의한 수동조작 없이 최적의 영상을 얻을 수 있도록 한 것이다.The present invention is Mr. Video. A video signal selection processor used in a player, the video signal generator. Read the data recorded on the video CD. A microcomputer 80 for determining whether the recording method is the NTSC method or the PAL method and generating a control signal, and a 3.58 MHz oscillator 85 for generating a 3.58 MHz color sub-carrier signal. ), 4.43 MHz oscillator 90 for generating a 4.43 MHz color subcarrier signal, and under the control of the microcomputer 80 to pass a 3.58 MHz subcarrier signal or 4.43 MHz subcarrier signal. The switching unit 100, the synchronization signal generator 120 selectively generating horizontal and vertical synchronization signals under the control of the microcomputer 80, and the 3.58 MHz subcarrier signal or the 4.43 MHz subcarrier signal horizontal and vertical And an RGB encoder 140 for converting and outputting a video signal provided by being converted into an analog signal according to the synchronization signal and outputting the RGB signal. That it or by processing the video signal appropriate in each case to determine whether the record in the PAL system, one will for optimum image without any manual operation by a user.
