ABSTRACT:
In the recording section of a system for recording and reproducing a television signal containing a video signal component and a sound signal component the length of recording time is increased for a given amount of recording medium by periodically sampling the video signal component, for example, for alternate frame periods, and the sound signal component and a delayed sound signal component obtained by means of an one-frame delay device are alternately sampled for the first half and the second half of each line period during the sampled frame period in order to be recorded on a recording medium and be reproduced from the recording medium. In the reproducing section, each recorded frame of the video signal component is reproduced twice in succession along with the sound signal component, and the reproduced sound signal component is sampled for the first half of each line period during the first reproduction of the recorded frame and for the second half of each line period during the second reproduction of the same frame.
