Abstract

PURPOSE:To increase the error correcting efficiency, by carrying out the detection and correction of error only to the data having a genuine error. CONSTITUTION:The original information signals are divided into two parts via a switch 11 and stored in buffer registers 12a snd 12b in the form of data trains X and Y respectively. The train Y is delivered via a delaying circuit 13, and then an interleaving operation of D is carried out for trains X and Y. The parities P1 and Q1 poduced by the 1st parity adding circuts 14a and 14b receive 2D and 3D delays 15a and 15b and then (d-D), 2(d-D) and 3(d-D) delays 16a, 16b and 16c to receive an interleaving control. These actions are repeated, and the information signal is recorded via a multiplexer 23. For reproduction of this information signal, the error correction is carried out for the parities in the order of P3, Q3, P2, Q2, P1 and Q1.
