Abstract
PURPOSE: To perform the correction of errors readily and accurately by subsequently recording data bits and parity bits, respectively as 1 unit, unit by unit within one horizontal synchronizing period of video signal.
CONSTITUTION: This is the system of converting 1 sample of analog signal to the digital signal of (n)bits, wherein in the case of superposing this digital signal on the video signal, the digital signal of the uppermost bit, so-called MSB, is recorded in the first 1H period A and the digital signal for the second bit being the next bit of the MSB is subsequently superposed on the video signal in the next 1H period B, thus the digital signal of the (n)th bit being the lowermost bit, so-called LSB, is recorded in the (n)th 1H period Z. Then, if the number of the bits that can be recorded during 1H is let to be l, the digital signals of l samples may be recorded by the use of the (n) horizontal synchronizing periods.
