Abstract
A system having a medium which presents signal sequences which at least partly consist of binary signal sequences and a device for generating a synchronization signal for synchronizing at least parts of said signal sequence (blocks, words). A binary signal sequence contains a synchronization pattern which consists of (2N+1) groups of codes of m+n bits. A number of (N+1) groups have a code content which exhibits a given, at least minimum Hamming distance with respect to the code (codes) of the other group (groups). The device includes a majority decision device which produces the synchronization signal by means of the n bit codes of said (2N+1) groups on the basis of a majority decision (N+1 out of 2N+1).
