DECODING DEVICE FOR A STREAM OF CODE SYMBOLS WHICH ARE WORD-WISE PROTECTED BY A DOUBLE REED-SOLOMON CODE |
摘要 |
<p>42 Decoding device for a stream of code symbols which are word-wise protected by a double Reed-Solomon code with a minimum Hamming distance of 5 over the code symbols and an interleaving mechanism between the two codes, and also a player comprising such a decoding device. For the decoding of a data stream which is wordwise protected against errors by a double Reed-Solomon code with symbol-wise interleaving over the code words, first the reliability information for the constituent symbols is aggregated for a code word. The strategy is determined therefrom, entailing the number of erase symbols and the maximum number of error symbols to be corrected. The correction result is compared with a reliability code and on the basis thereof all symbols obtain an at least trivalent secondary reliability indication for decoding in the second code.</p> |
