Abstract
본 발명은 엔티에스씨(NTSC)/고화질 티브이(HDTV)신호 변환회로에 관한 것으로, 현재 연구중인 고화질 티브이(HDTV)가 실용화되어도 일정기간동안 엔티에스씨 방식과 공종하게 될 것이다.The present invention relates to NTSC (NTSC) / HDTV signal conversion circuit, and even if the high-definition TV (HDTV) currently under study will be commercialized with the NTS system for a certain period of time.
이때, 엔티에스씨 신호를 고화질 티브이 신호로 변환하여 재현하거나 변환되어 송수신된 고화질 티브이신호를 엔티에스씨 신호로 복원하여 기록 또는 재현할 필요가 있다.In this case, it is necessary to convert the NTS signal into a high definition TV signal to reproduce or to reproduce or convert the high quality TV signal transmitted and received to the NTS signal to record or reproduce.
이러한 점을 감안하여 본 발명의 4개의 엔티에스씨 신호를 다중화시켜 고화질 티브이 신호로 변환하고 송수신된 고화질 티브이 신호를 줌(Zoom) 동작에 따라 고화질 모니터에 재현하거나 4개의 엔티에스씨 신호로 복원하여 기록 또는 재현하기 위한 것이다.In consideration of this point, the four NTS signals of the present invention are multiplexed and converted into a high-definition TV signal, and the high-definition TV signal transmitted and received is reproduced on a high-definition monitor according to a zoom operation or restored to four NTS signals. To record or reproduce.
따라서, 본 발명을 적용하면 고화질 티브이 신호와 엔티에스씨 신호를 동시 시청 또는 기록재생할 수 있다.Therefore, according to the present invention, the high-definition TV signal and the NTS signal can be simultaneously viewed or recorded and reproduced.
