Claims

[Scope of utility model registration request]

A television signal in which the phase order of reproduced chroma components of a reproduced video signal reproduced from a recording medium is disturbed during variable speed reproduction or still image reproduction, and a color television signal is output to an output terminal through reproduction processing of the reproduced video signal. In the recording and reproducing apparatus, a delay line circuit that holds the reproduced color television signal for one horizontal period, an omission detection circuit that detects omission of the reproduction video signal during normal reproduction, and an omission detection output of the omission detection circuit. a dropout switch that outputs the retained color television signal of the delay line circuit to the output terminal; a filter that extracts a chroma component of the reproduced color television signal; and a filter that outputs the retained color television signal of the delay line circuit to the output terminal; , a chroma detection circuit that detects a disturbance in the phase order of the chroma components extracted by the filter during the variable speed playback or the still image playback, and a chroma detection circuit that is switched by the disturbance detection output of the chroma detection circuit to output the retained color television signal. A television signal recording and reproducing device equipped with a chroma switch that outputs to a terminal.
