Abstract

본 발명은 CCIR(International Radio Consultative Committee) 권고안 656형식의 영상 신호를 2채널 디지탈 인코더의 입력으로 이용할 수 있도록 CCIR 권고안 656을 참고하여 하드웨어로 구현한 것이다.The present invention is implemented in hardware with reference to CCIR Recommendation 656 so that a video signal of the International Radio Consultative Committee (CCIR) Recommendation 656 format can be used as an input of a two-channel digital encoder.

본 발명은 CCIR 656영상신호를 입력하여 이 신호에서 타이밍 기준 신호의 값을 알아내 이 값을 이용하여 화소화 라인 카운터를 작동 시켜 카운터의 출력 신호인 화소와 라인 번지수의 조합을 이용하여 656신호를 동기 신호와 CCIR 601의 데이타로 변환하는 장치를 제공한다.The present invention inputs the CCIR 656 image signal to find the value of the timing reference signal from the signal, and operates the pixelized line counter using this value to generate the 656 signal using a combination of pixel and line address, which are the output signals of the counter. The present invention provides an apparatus for converting a signal into a synchronization signal and data of a CCIR 601.
