Abstract
In a multiplex transmission method, a plurality of digital signals having different frame lengths and bit-synchronized at the same signal rate are transmitted after the signals are multiplexed in a predetermined order. The received multiplexed signal is demultiplexed. A predetermined sync pattern is detected from each digital signal obtained by demultiplexing. The output position of each digital signal is determined on the basis of the sync pattern detection result. A multiplex transmission system is also disclosed.
