Abstract
A phase standard position signal generator generates a phase standard position signal of a predetermined period indicating the phase standard position of an image signal of 24 frames/second format, for recordation into a recording reproducing medium. In reproducing from the recording reproducing medium, a phase standard position sensor senses the phase standard position signal. A counter performs frequency quintuplication of the phase standard position signal and counts the period of the frequency-quintupled signal. A time code reader reads a 24 Hz time code value from the recording reproducing medium. A time code generator calculates a 30 Hz time code with the use of the counted value given by the counter and the 24 Hz time code value. Thus, the time code of 24 Hz period is converted into the 30 Hz time code with high precision even in variable-speed reproduction.
