Abstract

PURPOSE:To reduce the occurring probability for incapability of transmission, by designing previously the multiplex degree based on the average redundancy suppression factor and blocking the idle channel when the using efficiency of transmission line exceeds a certain level to inhibit the new input signal. CONSTITUTION:Each signal supplied from the four input signal channels 5 is coded after receiving a suppresion of redundancy through the redundancy suppressing and coding circuit 3. The multiplying circuit 4 multiplies the coded signal and then sends it onto the transmission line 6. In this case, the using efficiency measuring instrument 1 of transmission line monitors the transmission line using factor based on the information to be sent onto the line 4. Thus the input signal gate 2 is controlled.
