Abstract

Data reliability at the output of the error-correction code decoderin a compact-disc system is influenced by the decoding strategyemployed by the decoder, as well as by the statistical distribution oferrors that contaminate the recorded data. Recovered-datareliability estimates have been computed by use of error statisticsobtained from the measurement of errors that contaminate the actualdata stored on clean write-once and read-only-memory compactdiscs. These estimates consist of probabilities that specify theoccurrence of residual errors in the data that appear at the output ofa compact-disc player’s cross-interleaved Reed–Solomon code(CIRC) decoder. Data reliability estimates that apply to fivespecific CIRC decoding strategies are reported.

We subsequently obtained C1 code words by mathematically performing the deinterleaving step that rearranges the sequential byte stream at the CIRC input to form the corresponding sequence of C1 code words.
