Claims (10)
- 출력측에, 문자 또는 그래픽을 표시하는 애널로그 텍스트 신호기 출현하는 텍스트 디코더를 구비한 비디오 레코더에 있어서, 출력측이 매트릭스(11)의 입력측에 접속되어 있으며, 이 매트릭스의 출력측(12)은 스위치(S2)를 통하여 반색조 신호(Yg)를 운반하는 프로세서(7)에 접속되어 있는 것을 특징으로 하는 텍스트 디코더를 구비한 비디오 레코더.
- 제 1항에 있어서, 스위치(S2)는 텍스트 신호에 대한 레코더 출력측(5)과 레코더의 기록로(7)와의 사이에 설치되어 있는 것을 특징으로 하는 텍스트 디코터를 구비한 비디오 레코더.
- 제 1항에 있어서, R, G, B 텍스트 신호의 진폭은 0%또는 완전포화채도(complete color saturation)에 상당하는 100%중 어느 하나인 것을 특징으로하는 텍스트 디코더를 구비한 비디오 레코더.
- 제 1항에 있어서, 매트릭스(11)에 있어서의 반색조 신호(Yg)가 Yg= 0.59G + 0.3OR + 0.11B 또는 그것과는 근소한 차이를 갖는 PAL 규격에 따른 R, G, 텍스트 신호로 이루어지는 것을 특징으로 하는 텍스트 디코더를 구비한 비디오 레코더.
- 제 1항에 있어서, 재생시 R, G, B 신호들이 순색채도(full color saturation)의 R, G, B 신호로부터 주지된 매트릭스 연산을 기초로 하여 반색조 신호(Yg)로부터 복원되는 것을 특징으로 하는 텍스트 디코더를 구비한 비디오 레코더.
- 제 5항에 있어서, 반색조 신호(Yg)가 R, G, 신호를 생성하기 위해 회로(15)에 공급되는 출력전압을 갖는 진폭판별기(17)에 공급되는 것을 특징으로 하는 텍스트 디코더를 구비한 비디오 레코더.
- 제 6항에 있어서, 진폭판별기(17)의 출력측이 텍스트 신호를 포함하는 복합 컬러텔레비젼 신호가 발생되는 엔코더(16)의 입력에 연결되는 것을 특징으로 하는 텍스트 디코더를 구비한 비디오 레코더.
- 제 1항에 있어서, 텍스트 신호디코더(10)와 매트릭스(11) 및/또는 엔코더(16)를 포함고 있는 회로(9)는 그 입력측에 전환스위치(S3)에 의하여 선택적으로 수신 튜너(6)의 복한 컬러텔레비젼 출력 신호 또는 재생로(7)의 복합 컬러텔레비젼 신호가 접속 가능하도록 제공되며 또한 회로의 출력측(12)은 레코더의 신호출력측(5)에 접속되어 있으며 또한 전환 스위치(S2)를 통하여 기록로(7)에 접속가능한 것을 특징으로 하는 텍스트 디코드를 구비한 비디오 레코더.
- 제 1항에 있어서, 매트릭스(11)에 반색조 신호(Yg)로부터 대응하는 복합 컬러텔레비젼 신호를 발생하는 엔코더(16)가 배속되어 있는 것을 특징으로 하는 텍스트 디코더를 구비한 비디오 레코더.
- 제 1항에 있어서, 매트릭스(11)는 선형이며 기중된 가산단의 형태로 실현되는 것을 특징으로 하는 텍스트 디코더를 구비한 비디오 레코더.
