する２システムＶＴＲ０[Claims for Utility Model Registration] Frequency conversion of an input color signal by the output of a PAL color subcarrier oscillator and the output of a horizontal synchronization signal multiplier circuit to derive a high-frequency converted color signal or a low-frequency converted color signal In a two-system PAL and SECAM VTR, the frequency division value of the comparison signal of the PLL circuit included in the multiplier circuit is determined by the output of the color identification circuit that identifies reproduction of the SECAM color signal from the burst signal after high-frequency conversion. and set the multiplication value (44-1/4) when reproducing the SECAM signal.
A two-system VTR0 characterized in that fH (where fH is a horizontal synchronization frequency) and a multiplication value other than when reproducing SECAM signals are set to (44±178) fH [however, the sign is inverted for each field].
