Abstract

PURPOSE:To reduce the number of transmitting lines and to decrease a cable and a laying cost by changing the pulse width of a synchronizing signal for display, which is inserted in a non-display period and transmitting information except for display information. CONSTITUTION:To an input device 3, an superimposing device 10 is provided to superimpose a CRT display signal S1 and a signal S2 for speaker operation and to send them to a coaxial cable 5. When the signal S2 for speaker operation is impressed to the device 10, the time width of the synchronizing signal, which is inserted to the non-display period of the CRT display signal S1, is changed. A display device 4 equips a signal separating device 11, which separates an superimposing signal from the coaxial cable 5 into the CRT display signal S1 and the signal S2 for speaker operation, and a CRT 12.
