Abstract
There is provided a receiving system for receiving the video signal for each one frame. The video signal is divided into line signals each corresponding to the horizontal scanning period and transmitted sequentially in such a manner that each line signal is inserted in a television signal during each vertical blanking period. The line signals inserted in the transmitted television signal are separated therefrom and the separated line signals are selectively recorded on the odd and even field tracks of a rotary recording medium. Switches for selectively recording the line signals on the even field and odd field tracks are controlled by the output of an odd/even field selection signal generating circuit. The number of revolutions of the rotating recording medium is determined so that the line signals selectively recorded on the even field and odd field tracks of the rotating recording medium are arranged in the correct order and without leaving any spaces between the line signals or causing the line signals to overlap with each other. When the video signals for one frame have been recorded on the rotating recording medium, the one-frame video signals recorded on the rotating recording medium are repeatedly read out to reproduce a still picture.
