摘要

An information transmission method with error correction for user words, an error correcting decoding method for such user words, an apparatus for information transmission for use with the method, a device for information decoding for use with the method, and an apparatus for use with such device.;There is described a method and apparatus for error correcting data transmission between a user device and a medium. The information integrity is maintained by a first and second cross-interleaved Reed-Solomon code. A third Reed-Solomon code is overlaid on the CIRC code in that a sector is built from user words and protected by a quasi- product code. Then an encoded sector is divided into groupts, which are group-wise presented to the CIRC encoder.
