A multiplexing apparatus stores fixed length data into which information signals supplied from channels are divided; determines an output channel by selecting the each channel cyclically; and acquires the fixed length data from the output channel based on a channel multiplexing ratio number to store the fixed length data in a payload in turn. Also, the multiplexing apparatus adds assignment information, which includes a channel arrangement of each channel of the fixed length data stored in the payload, to the payload. Further, the multiplexing apparatus creates a multiplexing frame by using the payload to transmit to a transmission channel. A demultiplexing apparatus detects the assignment information from the payload of the multiplexing frame received to the transmission channel; and creates distribution information for distributing the fixed length data to each channel based on the assignment information. Also, the demultiplexing apparatus detects the fixed length data from the payload to distribute the fixed length data to each channel based on the distribution information. Further, the demultiplexing apparatus couples the fixed length data to reproduce the information signal. |
