Abstract
PURPOSE: To reduce the error in the picture control signal due to noise on the transmission line, by repetitively transmitting the video control signal with a plurality of times, in transmitting the still picture one screen.
CONSTITUTION: In transmitting one screen of the still picture, in addition to the video signal 15 representing the content of picture, the video control signal 16 representing the output terminal to be outputted at the reception side is added and superimposed on a plurality of locations within the vertical blanking time 13. The video control signal like this is separated from the picture signal 15 from the video control signal separation circuit 9 in the reception unit 2 and it is sequentially stored in the memory register 17. Further, the majority decision logic is taken between a plurality of picture control signals stored with the majority decision logic circuit 18 to estimate correct picture control signal. The selector switch 11 is controlled with the output and the video signal 15 is outputted to the output terminal estimated correct.
