Abstract

PURPOSE:To improve coexistence with voice multiplex broadcasting and facsimile multiplex broadcasting, by increasing the frequency of subcarrier wave for facsimile by even number times of the specified frequency fS1 of subcarrier wave for voice. CONSTITUTION:A subcarrier wave for voice and a subcarrier wave for auxiliary are modulated by a subchannel signal for voice and a subchannel signal for auxiliary such as for facsimile and for static picture. Multiplex compound signal is obtained by superposing the modulated subcarrier wave for voice and subcarrier wave for auxiliary on a master channel signal of voice. This is the transmitting method of TV multiplex signal by frequency modulating the master carrier wave of voice with the use of this multiplex compound signal, and the interference level of subchannel signal for auxiliary against subchannel signal for voice is decreased by increasing the subcarrier wave for auxiliary by even number times of the subcarrier wave of voice, for example by four times.
