<p>PROBLEM TO BE SOLVED: To provide a multiplex system where the discontinuity of data does not occur by designating packets which are multiplexed and outputted to the multiplex output means of plural multiplex devices. SOLUTION: When the packet input parts G1-Gn of a multiplex device 11 start the input operations of packets, they hold the inputted packets until a multiplex output part K reads the packet. The multiplex output part K reads the specified packet in accordance with selection instruction information which a selection instruction switch part J makes to be valid and multiplexes/outputs it. When the packet input parts Q1-Qn of a multiplex device 12 start the input operation of the packets, they hold the inputted packets until a multiplex output part U reads the packet. The multiplex output part U reads the specified packet in accordance with selection instruction information which a selection instruction switch part S makes to be valid and multiplexes/outputs it. Thus, the discontinuity of output data does not occur even if the output object of the packet is switched from the arbitrary multiplex device to the other multiplex device.</p> |
