ABSTRACT:
Information is transmitted by a digital audio transmission line, which may include recording and playback from a digital audio disc, that includes information other than conventional two-channel audio signals and in which error correction of the data transmitted in either direction between a user and a medium is provided. Information integrity is maintained by a first and second cross-interleave Reed-Solomon code (CIRC), in which a third Reed-Solomon code is overlaid on the CIRC code, whereby a sector is built from user words and protected by a quasi-product code, and then an encoded sector is divided into groups, which are group-wise presented to the CIRC encoder.
