A digital signal multiplexing device packetizes one or more bitstreams of digital signals to form packets and multiplexes the respective bitstreams on the packet basis to produce plural degree-one multiplexed streams which are received. The digital signal multiplexing device also sets the sequence of time-divisional multiplexing of the packets as interleaving patterns repeated at a pre-set period. The digital signal multiplexing device time-divisionally multiplexes the degree-one multiplexed streams on the packet basis to generate a degree-two multiplexed stream.
