Abstract
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; 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; adds assignment information to the payload; and 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; creates distribution information for distributing the fixed length data to each channel based on the assignment information; detects the fixed length data from the payload to distribute the fixed length data to each channel based on the distribution information; and couples the fixed length data to reproduce the information signal.
