Abstract

PURPOSE:To establish excellent video quality, by performing the delivery and reproduction of the video signal in the band of 1/n for the output signal band through picking up the output signal of the pick up camera at the transmission end every n line per one frame. CONSTITUTION:The original video signal outputted by the pick up camera is picked up every n line per one frame, separate line is picked up every n line as to the next one frame, and similarly the switch 5 picking up the signal on all the lines for the original video signal in n frame is provided at the output end of the transmission unit 1. Further, the signal picked up from the switch 5 is expanded n times time with the time expansion circuit 6 and delivers it to the narrow band signal delivery line. Thus, by performing delivery and reproduction for the video signal in the band of 1/n of the output signal band of the pick up camera, efficient narrow band delivery ismade and excellent video quality can be obtained.
