1 PHN. 9281. A system comprising a medium which presents signal sequences which at least partly consist of binary signal sequences and a device for generating a synchronisation signal for synchronizing at least parts of said signal sequences (blocks, words). A binary signal sequence contains a synchronisation pattern which consists of (2N + 13 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). This device comprises a majority decision device which produces the synchronisation signal by means of the n bit codes of said (2N + l) groups on the basis of a majority decision (N I 1 out of 2N + 1). The system may be, for example, a communication system or a storage system comprising a medium in the form of a record carrier.
