Abstract
PURPOSE: To secure the display for the characters, patterns and others on the color picture receiver after the color submodulation through a simple constitution by mixing the signals obtained through addition of the signals of plural different luminance levels with the output signals of the 1st mixer circuit.
CONSTITUTION: Oscillation circuit 1 oscillates the continuous signals featuring the frequency of 6 times as much as the chrominance subcarrier, and square wave generation circuit 2 generates the signals of the 6-phase symmetrical square waves according to the output of circuit 1. Here gate circuit 4 samples the signals of the symmetrical waves corresponding to the color burst signals via the burst flag pulse among the 6-phase symmetrical square wave signals. And the output of circuit 4 is mixed 5 with the output of symmetrical square wave selection circuits 3, 5 and 6, and then mixture 9 is given between the output signals obtained through addition 7 among the signals of plural different luminance levels and the output signals of mixer circuit 5. In such way, the characters, patterns and others can be displayed on the color picture tube after the color submodulation in a simple constitution.
