Digital video signal recording/reproducing apparatus.

摘要

In a digital video signal recording/reproducing apparatus suited to recording of digital VTR video and audio signals by using a rotary cylinder, as for the video signal with frame frequency fN of 30 Hz or 29.97 Hz, the rotating frequency of the cylinder is set to 2.5 times fN. On the other hand, as for the signal with frame frequency fP of 25 Hz, the rotating frequency of the cylinder is set to 3.0 times fP. As a result, as far as the cylinder diameters are identical, the relative speed of tape and head is the same for the video signals of either frame frequency fN or fP.
