Claims (2)

더블스캔 TV에 텔레텍스트를 수신가능토록함에 있어서, 아날로그 텔레텍스트 색신호를 디지탈 색신호로 변환시켜 각각의 라인메모리에서 더블스캔용 신호로 만든후 다시 아날로그 색신호로 변환시키는 수단과, 이 버블스캔용 아날로그 텔레텍스트 색신호를 TV색신호와 스위칭하여 선택적으로 출력되도록한 수단을 구비하여 DSD-TV에서 일반TV의 텔레텍스트 수신을 가능하도록한 것을 특징으로 하는 더블스캔 디지탈 TV에 있어서 텔레텍스트 이용방법.Means for converting the teletext to a double scan TV, converting the analog teletext color signal into a digital color signal, converting it into a double scan signal in each line memory, and then converting the analog color signal back into an analog color signal; A method of using teletext in a double scan digital TV, comprising means for switching a text color signal to a TV color signal to selectively output the text color signal. 제1항에 있어서, 각각의 색신호당 2개의 라인메모리를 설정하고 그중 한 라인메모리는 정상클럭을 받아 쓰기동작하는 메모리로하고 다른 한 라인메모리는 2배 빠른 클럭을 받아 같은 시간에 2배 속도로 하며 다음순간 서로 교체동작을 하도록 한 것을 특징으로 하는 더블스캔 디지탈 TV에 있어서 텔레텍스트 이용방법.2. The apparatus of claim 1, wherein two line memories are set for each color signal, one of which is a memory that receives a normal clock and writes, while the other is receiving a clock twice as fast and at twice the same time. And a method of using teletext in a double scan digital TV, which is to be replaced with each other next time. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
