Abstract (en)
[origin: WO8706368A1] Apparatus and methods for encoding information of one class into the parity for main data of another class. The methods and apparatus fundamentally take one member of a limited first class of data and concatenate it with main data (20). Parity is then calculated on the concatenate word (24). After the main data and parity is transmitted or recorded, the selected member from the first class of data may be recovered by comparing (48, 50) the main data and its parity to the parity generated on the receiver side using the main data and each member of the first class of data to generate a plurality of syndromes. The first all zero syndrome identifies the member of the first class which was encoded into the parity of the main data.
