Abstract

PURPOSE: TO reduce a correction frequency and eliminate the number of two- sample correction times to make it possible to correct errors easily by devising addition of parity signals.
CONSTITUTION: In case that signals L and R of stereophonic two channels are coded digitally and are recorded and reproduced, the signal sequence is separated into singal groups {L1,R2,L3,R4... and {R1,L2,R3,L4...} across each other, and these signal groups are subjected to interleave and are recorded and reproduced after parity signals are added to these signal groups respectively. Generally, N- channel and M-sample data is so extracted that continuous sample data of the same channel cannot exist for one parity signal, and parity signals are added to these segmented data groups. Then, the two-sample correction requiring a complicated signal processing is not required, and it is sufficient if the easy one-sample correction is performed simply.
