Decoding device for a record carrier provided with a multi-track data pattern which includes error protection data, and player comprising such a decoding device. |
摘要 |
<p>In a multi-track record carrier the data is stored in words which comprise an increased number of symbols as a result of added redundancy. In order to neutralize so-called burst errors, the symbols of a word are stored in a distributed manner, for example by interleaving. In the case of loss of track, a regrouped word may then actually consist of parts of two or more different words (i.e. words situated on several tracks). Decoding of such a word is prevented in practice in that a series of symbols are invalidated in the case of loss of track, for example by inversion or by means of an invalidity flag.</p> |
