Matrixing apparatus for a color television system

Claim 2

IN A COLOR-TELEVISION RECEIVER, MATRIXING APPARATUS FOR DEVELOPING FROM TWO MODULATION COMPONENTS, OCCURRING AT TWO PRESCRIBED ANGLES OF RECEIVED COLOR SUBCARRIER SIGNAL, AT LEAST TWO COLOR-REPRESENTATIVE SIGNALS AT ANGLES OTHER THAN SAID PRESCRIBED PHASE ANGLES, COMPRISING: TWO SOURCE MEANS, EACH FOR SUPPLYING ONE OF SAID TWO MODULATION COMPONENTS; AND LOAD CIRCUIT MEANS COUPLED TO THE SOURCES FOR MATRIXING THE TWO MODULATION COMPONENTS IN THREE PORTIONS OF THE LOAD CIRCUIT, ONE PORTION OF WHICH IS COUPLED IN COMMON TO THE OTHER TWO, IN PROPORTIONS AND SENSES TO DEVELOP SAID COLOR-REPRESENTATIVE SIGNALS AT SAID OTHER PHASE ANGLES IN THE LOAD CIRCUIT.

Claim 3

IN A COLOR TELEVISION RECEIVER INCLUDING A SOURCE OF A CHROMINANCE SIGNAL COMPRISING PHASE AND AMPLITUDE MODULATED COLOR SUBCARRIER WAVES, THE MODULATION OF SAID COLOR SUBCARRIER WAVES BEING SUCH THAT DEMODULATION OF SAID WAVES AT A FIRST PREDETERMINED PHASE WILL PRODUCE A R-Y SIGNAL, DEMODULATION OF SAID WAVES AT A SECOND PREDETERMINED PHASE WILL PRODUCE A B-Y SIGNAL, AND DEMODULATION OF SAID WAVES AT A THIRD PREDETERMINED PHASE WILL PRODUCE A G-Y SIGNAL, SAID RECEIVER ALSO INCLUDING A SOURCE OF REFERENCE OSCILLATIONS OF COLOR SUBCARRIER FREQUENCY, AND COLOR IMAGE REPRODUCING APPARATUS ADAPTED TO REPRODUCE COLOR IMAGES IN RESPONSE TO THE DELIVERY OF R-Y, B-Y, AND G-Y SIGNALS, RESPECTIVELY, TO RESPECTIVE FIRST, SECOND AND THIRD INPUT TERMINALS THEREOF, A COLOR DEMODULATOR SYSTEM COMPRISING IN COMBINATION: FIRST AND SECOND DEMODULATING MEANS EACH HAVING SEPERATE OUTPUT CIRCUIT MEANS FOR DEVELOPING RESPECTIVELY DIFFERENT FIRST AND SECOND COLOR SIGNAL OUTPUTS, MEANS FOR APPLYING REFERENCE OSCILLATIONS FROM SAID SOURCE TO SAID FIRST DEMODULATING MEANS IN A FOURTH PREDETERMINED PHASE DIFFERENT FROM ANY OF SAID FIRST, SECOND AND THIRD PREDETERMINED PHASES, MEANS FOR APPLYING REFERENCE OSCILLATIONS FROM SAID SOURCE TO SAID SECOND DEMODULATING MEANS IN A FIFTH PREDETERMINED PHASE DIFFERENT FROM ANY OF SAID FIRST, SECOND, THIRD AND FOURTH PREDETERMINED PHASES, MEANS FOR APPLYING MODULATED, COLOR SUBCARRIER WAVES FROM SAID CHROMINANCE SIGNAL SOURCE TO EACH OF SAID FIRST AND SECOND DEMODULATING MEANS, AND COMMON OUTPUT CIRCUIT MEANS COUPLED TO BOTH OF SAID FIRST AND SECOND DEMODULATING MEANS FOR PROVIDING A THIRD COLOR SIGNAL OUTPUT AND FOR CAUSING INTERACTION BETWEEN SAID FIRST AND SECOND DEMODULATING MEANS SUCH THAT THE FIRST COLOR SIGNAL OUTPUT PRODUCED IN THE SEPARATE OUTPUT CIRCUIT MEANS OF SAID FIRST DEMODULATING MEANS CORRESPONDS TO ONE OF SAID R-Y, G-Y AND B-Y SIGNALS, THE SECOND COLOR SIGNAL OUTPUT PRODUCED IN THE SEPARATE OUTPUT CIRCUIT MEANS OF SAID SECOND COLOR DEMODULATOR MEANS CORRESPONDS TO A SECOND ONE OF SAID R-Y, G-Y AND B-Y SIGNALS, AD THE THIRD COLOR SIGNAL OUTPUT PRODUCED IN THE COMMON OUTPUT CIRCUIT MEANS OF BOTH OF SAID FIRST AND SECOND DEMODULATING MEANS CORRESPONDS TO THEREMAINING ONE OF R-Y, G-Y AND B-Y SIGNALS, AND MEANS FOR COUPLING SAID FIRST, SECOND AND THIRD INPUT TERMINALS TO THE RESPECTIVELY APPROPRIATE OUTPUT CIRCUIT MEANS.
