Abstract
PURPOSE: To enable video signal to be reproduced in real time and desired time by recording the video signal at a specific ratio, running the tape at the speed corresponding to the value of that ratio and recording pulses of different duty ratios.
CONSTITUTION: When pulses Pt are reproduced from a tape 4 by a head 102 and are counted in a counter 123 through the reproduction side contacts p of s swtich 101, this value is displayed in a dispaly means 125 by way of a decoder 124. In this case, the pulses Pt at the recording are those per second and therefore if the pulse number having been reproduced is counted, it turns out that the absolute time at the recording is measured and displayed irrespective of the running speed of the tape 4. If the running speed of the tape is changed at the reproducing, the frequency of the reproduction pulses Pt change according to this, but since the duty ratio τ/T is constant irrespective of the tape speed at the reproducing, it changes only with the tape speed at the recording. Thereby, the signal may be reproduced in real time and desired time.
