Patent ID: 8792496

Claim:
A multiplexing transmission system comprising: a multiplexing apparatus including: a dividing section that divides information signals received from a plurality of channels to create fixed length data each having a predetermined fixed length, a storing section that relates said fixed length data to said plurality of channels to store said fixed length data, an assignment controlling section that stores channel multiplexing ratio number indicating a ratio of said fixed length data stored in a payload of a multiplexing frame among said plurality of channels, select each channel cyclically to determines an output channel, and output an assignment instruction for acquiring said fixed length data based on said channel multiplexing ratio number of said output channel, a multiplexing section that acquires said fixed length data from said storing section every time receiving said assignment instruction to store said fixed length data in said payload in turn, an assignment information adding section that adds assignment information to said payload, said assignment information including a channel arrangement of each channel of said fixed length data stored in said payload, and a frame creating section that creates multiplexing frame from said payload to transmit said multiplexing frame to a transmission channel; and a demultiplexing apparatus that includes: a frame terminating section that receives said multiplexing frame from said transmission channel, an assignment information detecting section that detects said assignment information from said payload of said multiplexing frame to create distribution information for distributing said fixed length data to said each channel based on said assignment information, a distributing section that detects said fixed length data from said payload to distribute said fixed length data to said each channel based on said distribution information, and a coupling section that couples said fixed length data to reproduce said information signal.
