1. A stereoscopic television receiver, comprising:

  • a first tuner for tuning a broadcasting signal received by an antenna in response to a first channel selection signal from a channel selector;

    a first demodulator for demodulating the output signal from said tuner;

    a first data separator for separating information data from the output signal of said first demodulator and outputting frequency data, stereoscopic program data and left/right data therefrom;

    a tuning controller for generating a second channel selection signal from said frequency data of said first data separator;

    a first sterepscopic program data identifier for identifying said stereoscopic program data from said first data separator;

    a first right data identifier for identifying said left/right data from said first data separator;

    an AND gate for logically combining the output signal from said first stereoscopic program data identifier with the output signal from said first right data identifier;

    a second tuner for tuning said broadcasting signal being received at said antenna by said channel selection signal from said tuning controller;

    a second demodulator for demodulating the output signal from said second tuner;

    first and second signal processors and for processing the respective output signals from said first and second demodulators and;

    first and second for outputting the output signals from said first and second signal processors as first and second LCD driving signals respectively;

    a switch for selecting the output signals from said first and second LCD drivers in response to the output signal from said AND gate; and

    left and right optical system for indicating the signals being output to first and second movable terminals of said switch on a television screen after converting the signals into video signals.
