제2도는 본 발명에 따른 칼라텔리비죤 전송계의 실시예를 보여주는 블록도.

Claims (6)

  1. 휘도신호 및 저역여파된 크로미넌스신호를 전송하는 칼라테리비죤 전송계에 있어서, 재생시의 휘도장애를 피하기 위하여, 전송측에서 감마전치보정 전에 색차신호(R-Y, B-Y)를 저역여파하는 것을 특징으로 하는 칼라텔레비죤 전송계.
  2. 제1항에 있어서, 감마전지보정된 휘도신호(EY) 및 감마전치보정된 크로미넌스신호(EUEV)로 부터 감마왜화(歪化)색신호(R,G,B)가 형성되는 것을 특징으로 하는 칼라테리비죤 전송계.
  3. 제2항에 있어서, 색신호(R,G,B)로부터 휘도신호(Y)와 색차신호(B-Y, R-Y)가 얻어지는 것을 특징으로 하는 칼라테리비죤 전송계.
  4. 제1항 내지 제3항 중 어느 한 항에 있어서, 색차신호(B-Y, R-Y)가 저역여파되는 것을 특징으로 하는 칼라테리비죤 전송계.
  5. 제4항에 있어서, 저역여파된 색차신호(B-Y, R-Y)및 회두신호(Y)로부터 색신호(R,G,B)가 형성되는 것을 특징으로 하는 칼라텔리비죤 전송계.
  6. 제5항에 있어서, 색신호(R,G,B)가 감마전치보정되어서 코더(19)로 공급되는 것을 특징으로 하는 칼라텔리비죤 전송계.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
