A digital broadband signal is divided into a plurality of subsignals by demultiplexing, each of said subsignals having a lower bit rate than the broadband signal and being distributed on and transmitted along its respective subchannel (11-16) like e.g. ordinary digital telephone channels having arbitrary propagation times. The differences in propagation time is compensated by transmitting at least one flag on each subchannel at start and by individually delaying the received signals in the receiver in response to the received flags, so that the broadband signal can be reestablished from the subsignals by multiplexing. No return signal path is needed in this automatic start, and the least possible delay is inserted to permit the broadband signal to be reestablished in operation. |
