Abstract
A supplied time code is multiplied to generate detailed time data. The detailed time data are latched at a given time in an input signal. The latched time data are converted into converted time data having a given data format. The converted time data are recorded in the same transmission path as the output signal.
Claims12
A method of recording a time code, comprising the steps of:
- multiplying a supplied time code to produce a product, thereby generating detailed time data;
- latching the detailed time data at a given time in a data input signal;
- converting the latched time data into converted time data having a given data format;
- and
- recording the converted time data in a same transmission path as the data input signal.

A method of reproducing a time code, comprising the steps of:
- multiplying a supplied time code to produce a product, thereby generating detailed time data;
- latching the detailed time data at a given time in a data input signal;
- converting the latched time data into converted time data having a given data format;
- reproducing the converted time data in a same transmission path as the data input signal;
- measuring a time ratio between recording and reproducing time data;
- controlling a reproduced clock signal according to the ratio;
- presetting the time data in a counter;
- and
- supplying the controlled reproduced clock signal to said counter to produce a count of the counter as a reproduced time code.
