ABSTRACT:
A multiplex TV signal processing apparatus in a television signal transmitting and receiving system includes an apparatus at the transmitting side which has a first amplitude-modulator for modulating a first carrier by a main signal to obtain a vestigial side-band amplitude-modulated main signal; a second amplitude-modulator for modulating a second carrier but whose frequency is the same as which phase is 90 degree different from the first carrier by a sub signal to obtain a carrier suppressed amplitude-modulated signal; a first inserter for inserting a first ghost canceling reference signal into a horizontal line of the main signal during a vertical blanking period; a second inserter for inserting a second ghost canceling reference signal into the same horizontal line of the sub signal as the first ghost canceling reference signal; and includes an apparatus at the receiving side which has: a first demodulator for demodulating the main signal; a second demodulator for demodulating the sub signal; a ghost canceler for canceling a ghost of the sub signal using the second ghost canceling reference signal; and a crosstalk canceler for canceling the crosstalk of the sub signal from the main signal using the first ghost canceling reference signal.
