Abstract

See full text

A stream of incoming digital signals (I.sub.a) is split (10) into a plurality of derived streams (I.sub.b) that are sent over respective transmission links (R). The derived streams transmitted in this way (I.sub.c) are then bundled again (20) to form a stream of outgoing digital signals (I.sub.d). At the transmission end, symbols are inserted into the derived streams (I.sub.b) simultaneously and at constant intervals (T), in order to subdivide the transmitted information into packets of equal duration and aligned in time when being transmitted. At the reception end, the above symbols associated to the transmitted derived streams (I.sub.c) are generally time-shifted as a consequence of the transmission over the various transmission links (R). At the reception end (20) the time alignment of the above symbols is recovered so as to recover the time alignment of the various transmitted derived streams (I.sub.c), so that the subsequent bundling can take place on the streams correctly time-aligned.
