Abstract
PURPOSE: To increase the value of utilization of VTR, by constituting the system that the tape after recording with other systems is reproduced as it is and the system conversion is made, and by enabling the reception with the TV receiver used in other districts.
CONSTITUTION: Taking the field frequency as F1 and the number of scanning lines for one filed as N1, the tape recorded with the rotary head in the track tilt toward lengthwise of tape through running in the speed of S1 at recording is reproduced with the reproducer having the field frequency F2, number of scanning lines for one field N2, tape running speed S2 at reproduction, and the length of scanning locus for one field l2. In this case, the reproducer is used, in which the head revolving speed and the rotary head drum diameter and the tape wrapping angle to the rotary head drum are selected so that the relation between the tape running time S2 and the length of scanning locus l2 is S2=F2/F1(S1) and l2 =N2/N1 (Cl1), and the circuit converting the low band conversion carrier signal reproduced with this unit into the chroma subcarrier frequency f2 for the carrier chrominance signal, is provided.
