Abstract:
A method of transmitting digital signals, wherein a stream of incoming digital signals (Ia) is subdivided into a plurality of derived streams (Ib) to be transmitted on respective transmission links (R) and the derived streams so transmitted (lc) are bundled again at a reception end to form a stream of outgoing digital signals (Id), comprising the operations of:inserting into said derived streams (Ib), simultaneously and with constant periodicity (T), symbols (S) that subdivide the information transmitted on said transmission links into packets of a same duration and time aligned during transmission, the duration of said constant periodicity being at least twice a maximum time shift (D) between transmitted derived streams (Ic), recognizing at said reception end said symbols (S) within said transmitted derived streams (Ic), the symbols associated to different derived streams being in general mutually time-shifted due to the transmission on said transmission link, recovering the time alignment of the information packets present in said transmitted derived streams (lc) by recovering the time alignment of the respective symbols (S), and bundling again the transmitted derived streams (lc) after having recovered the time alignment of the respective information packets.
