Abstract

PURPOSE:To obtain a static picture through a simple constitution, by providing a frequency-phase converter with which an in-phase and an adverse phase output are obtained at a low frequency band and a high frequency band respectively and then deciding whether or not the chroma signal is made to pass through said converter in accordance with the reference filed. CONSTITUTION:Reproduced video signals in the same frame which are reproduced by a storage means are separated to a luminance signal Y and a chroma signal C through a comb-shaped filter 1. The signal C is supplied to a contact (a) of a switch 7 as well as to a contact (b) after turned into an in-phase or adverse phase chroma signal at a low frequency band or a high frequency band respectively through a frequency-phase converter 8. In case the reference field is set at the 1st and 2nd fields by the switch 7, the chroma signal C received no phase inversion is added with the signal Y at an adder 4. While the signal C received a phase inversion is added with the signal Y at the adder 4 when the reference field is at the 3rd and 4th fields. Thus a color video signal restored to an NTSC signal is obtained.
