Claim Text:
1. A process of encoding information data in a sequence of bursts ( . . . , B i−2 , B i−1 , B i , B i+1 , . . . ), each burst comprising a block of information symbols (D i ) and a block of redundancy symbols (R i ), the process comprising generation of the block of redundancy symbols (R and generation of a second sub-block (R i,1 ) of the block of redundancy symbols (R i ) of the current burst (B i ), which includes calculation of a sum of a second series of coding values relating to a second series (S 1 ) of bursts (B i−4 , B i−3 , B i−2 , B i−1 ), each coding value of the second series of coding values being obtained by a respective coding function applied to the block of information symbols of the corresponding burst of the second series (S 1 ) of bursts, the first (S 0 ) and second (S 1 ) series of bursts being of different lengths, and each coding function being a function, which, applied to a block of symbols, provides, as coding value, the redundancy symbols of a correcting code and which has the property of using all the symbols of the block to which it is applied, such that, if the value of any single symbol of the block is changed, the coding value obtained also changes.
