Stereoscopic television broadcasting system and a stereoscopic television receiver
First Claim
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.

Abstract
A stereoscopic television broadcasting system is provided which can televise the stereoscopic broadcasting of the left video and right video through two channels at the broadcasting station by inserting stereoscopic program data, left/right data and frequency data into the vertical retrace line intervals of the left video signal and the right video signal. A stereoscopic television receiver is provided which can display a stereoscopic picture thereon according to the broadcasting system, which includes a data separator for separating information data from the output signal of a tuner and outputting frequency data, stereoscopic data and left/right data therefrom, a tuning controller for generating a channel selection signal from the frequency data, a stereoscopic program data identifier and a right data identifier each for identifying the stereoscopic program data and left/right data of the separator, and an auxiliary circuit.

11. A stereoscopic television broadcasting system comprising:
-
processing means for processing a video signal into stereoscopic program data, left/right data and frequency data, said stereoscopic program data being processed when said video signal is transmitting said stereoscopic broadcasting television program, said left/right data being processed when a video signal is transmitting left and right video signals and said frequency data being processed when said video signal is being outputted from first and second channels of said stereoscopic broadcasting television program into vertical retrace line intervals of said left and right video signals; and display means for displaying said video signal corresponding to said stereoscopic program data, said left/right data and said frequency data processed by said processing means.
