Description

휘도신호와 저역통과 필터링이된 크로미낸스신호의 전송을 가지는 칼러텔레비젼 전송시스템Color TV transmission system with transmission of luminance signal and low pass filtered chrominance signal

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제 1도는 칼러텔레비젼 시스템의 원리배치도.1 is a principle diagram of a color television system.

제 2도 내지 3도는 도표들이며.2 to 3 are diagrams.

Claims (4)

휘도신호들과 저역통과 필터링된 크로미낸스신호의 전송을 가지는 칼러텔레비젼 전송시스템에 있어서, 재생시에 휘도결함을 회피하기 위하여 전송하려는 신호에게 특히 휘도신호에게 보정신호(Ey)가 가하여지며 이 보정신호는 신호높이 부분으로부터 얻어지는 것을 특징으로 하는 칼러텔레비젼 전송시스템.In a color television transmission system having transmission of luminance signals and low-pass filtered chrominance signals, a correction signal (especially a luminance signal) is applied to a signal to be transmitted to avoid luminance defects during reproduction. E y ) is applied and the correction signal is obtained from the signal height portion. 제1항에 있어서, 보정신호(Ey)는 색채화면 튜브의 제어를 위하여 3개의 모든 제어신호에 겹쳐지는 것을 특징으로 하는 칼러 텔레비젼 전송시스템.The method of claim 1, wherein the correction signal E y ) is a color television transmission system, characterized in that superimposed on all three control signals for the control of the color picture tube. 제1항에 있어서, 전체휘도 신호는 다음 공식 Y기준치=aB(F′-U_L+Ey2+Ey)y+aR(E′-V_L+Ey2+Ey)y+aG(E′W2L+Ey2+Ey)y을 만족시키는 것을 특징으로 하는 칼러텔레비젼 전송시스템.The method of claim 1, wherein the overall luminance signal is represented by the following formula Y reference value = a B (F ' -U_L + E y2 + E y ) y + a R (E' -V_L + E y2 + E y ) y + a G ( E ′ W2L + E y2 + E y ) y to satisfy the color television transmission system. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
