ABSTRACT:
A recording apparatus extracting and recording for reproduction a video signal of a still-picture out of a received multiple signal, which video signal is divided for every several horizontal scanning lines and inserted in the vertical fly-back period of an ordinary television signal included in the multiple signal, comprises means for extracting and recording sequentially the video signal for a still-picture from out of the vertical fly-back period of the television signal, and means for extracting by detection of that vertical synchronizing signal of the television signal which is the nearest to a position where the vertical synchronizing signal of the video signal for a still-picture should be located, and for recording the extracted vertical synchronizing signal together with the extracted video signal for a still picture.
