PURPOSE:To prevent deterioration of a picture quality, by compensating and dubbing a time axis of a reproduced luminance signal and a chrominance signal, making a local horizontal synchronizing signal a reference. CONSTITUTION:A reproduced luminance signal which is obtained by an output of an LPF19 is led to a CCD33, and is led to a horizontal synchronization separating circuit 29, as well. By an output of the circuit 29 is obtained a horizontal synchronizing signal having jitter which is contained in the luminance signal. On the other hand, to a terminal 30 is provided a local reference horizontal synchronizing signal, and a luminance signal whose time axis is compensated by an output of the CCD33 through a VCO32. In this same way, an I signal and a Q signal whose time axis and timing are compensated are obtained by outputs of CCD39, 40. These signals are dubbed by other VTR through a dubbing terminal 41. |
