Claim One:
1. A receiving method for a digital stream by a receiver, the stream comprising frames having each a body composed of a variable number c of symbols preceded by a header including a number d of symbols, the header comprising at least one field composed of a fixed number e of symbols to the receiver and defining the number c, wherein the receiving method comprises a locking phase comprising: a) receiving at least one series of e symbols of the digital stream; b) for a plurality of first pairs of received symbols, performing a correlation computation between the symbols of each pair, wherein the correlation computation is used to verify a first predefined relationship; c) determining a correlation level on the basis of the performed correlation computation—; and d) repeating a), b) and c) until the correlation level exceeds a predetermined threshold, wherein the at least one field comprises a fixed number e of symbols unknown to the receiver forming an unknown field, and wherein the locking phase further comprises: during b), verifying, with the correlation computation, a second-predefined relationship if the e symbols form the unknown field, during c), determining whether the e symbols of the digital stream form the unknown field based on the correlation level, during d), repeating a), b) and c) until it is determined that the e symbols of the digital stream form the unknown field.
