ー方式判別回路。[Scope of utility model registration claim] When recording, PAL color video signal and SECA
The M color video signal color component is converted to low frequency using a common or almost common conversion carrier and recorded, and the low frequency converted color signal is converted to high frequency using the conversion carrier during playback. In a double cassette type VTR housed in a stand, each VTR is provided with two color carrier separation circuits that separate the color component before reduction conversion during recording and the color component after high frequency conversion during playback; a selection switch that alternately selects the output of the carrier separation circuit; a PAL/SECAM discrimination circuit that inputs the output of the selection switch to discriminate between color systems; A color system discrimination circuit for a double cassette type VTR, which includes a distribution circuit for supplying the
