Abstract

PURPOSE:To prevent deterioration in teletext information signals and to properly reproduce teletext information by prohibiting an action as a comb-line filter to a luminance signal Y as for a signal at least during a period in which teletext information is superimposed. CONSTITUTION:As for the signal during the period in which teletext information is superimposed among composite video signals during a vertical flanking Y/C separation is not executed the signals are outputted as luminance signals Y, as they are. Accordingly, in thus outputted signals, the teletext information does not deteriorate in quality, and when the signals of the information are stored in a video signal recorder, teletext information can be obtained properly by reproducing thus recorded signals.
