Abstract

PURPOSE: To increase the transmission efficiency, by adding the identifying signal to identify signals and transmitting the signals with one transmission system, in the transmission of multiplex for one or the both of analog and digital signals.
CONSTITUTION: When the vertical synchronous signal taken as the first signal 1 and the horizontal synchronous signal taken as the second signal 2 are transmitted in negative logic, the analog signal B and binarized digital signal C are superimposed on the level A between adjacent second signals 2 to multiply the both signals B and C. Further, the identifying signal D to identify the both signals B and C is added and after voltage - light conversion, signal transmission is made on one transmission line such as optical fiber to make easy the identification of each signal at the reception side and to increase the transmission efficiency of signal.
