Caption signal recording and reproducing control device in video cassette recorders

A device for controlling recording and reproducing of caption signals of a video cassette recorder comprising:

• a broadcasting signal demodulation part for demodulating broadcasting signals received from a broadcasting station through an antenna;
• a first selection switch for selecting one source of signals either from the demodulated signals in the broadcasting signal demodulation part or other input signals;
• an image processing part having an image recording part for recording signals selected by the first selecting switch on a tape, and an image reproduction part for reproducing image signals recorded on a tape;
• a second selection switch for selecting so as to be able to record image signals transmitted from the image recording part in the image processing part in recording mode and reproduce image signals recorded on a tape in the image reproduction part in reproduction mode;
• a third selection switch for selecting one source of image signals from output signals of the image recording part and the image reproduction part in the image processing part;
• a fourth selection switch for selecting one source of signals from the image signals applied from the image reproduction part in the image processing part and the broadcasting signal demodulation part;
• a caption signal demodulation part for demodulating caption signals of the image signals selected by the fourth selection switch;
• a first mixer part for mixing the caption signals applied from the caption signal demodulation part with the image signals applied from the broadcasting signal demodulation part and applying the mixed signals to the first selection switch at one input terminal thereof;
• and
• a second mixer part for mixing the caption signals of the caption signal demodulation part with the image signals selected by the third selection switch.
