PURPOSE:To obtain a necessary sufficient digital MUSE signal and to lower the recording density by adopting an A/D converting device with a PLL circuit as the sampling circuit in the MUSE system digital VTR and making the sampling clock into the resampling clock of the special MUSE signal. CONSTITUTION:To a video signal input terminal 105, the analog MUSE signal outputted from an analog MUSE signal source is inputted. The input analog MUSE signal is limited to the band of 8.1MHz by an input side low pass filter 110. In the next A/D converting device 300, the analog MUSE signal is sampled at 16.2MHz in accordance with the clock of 16.2MHz supplied from a PLL circuit 310. The PLL circuit 310 detects the phase error of the sampling clock to reload correctly the digital MUSE signal at the transmitting side and the present sampling clock, from the digital signal sampled by the A/D converting device 300, and obtains the sampling clock to correct the phase error for the A/D converting device 300, namely, the sampling clock.
