Abstract

PURPOSE: To secure the display for the information of the characters, patterns and others on the TV picture receiver in a simple structure by generating the 6-phase symmetrical square wave signals with delay and then sampling the signals approximate to the color burst signal for mixture with the output of the selection circuit.
CONSTITUTION: Symmetrical square wave generation circuit 2 generates through circuit 2a, 2b and 2c each the 6-phase symmetrical square wave signals featuring the uniform phase difference of 60° in accordance with the output of oscillation circuit 1. And the phase is delayed individually for those square wave signals through circuits 2d, 2e and 2f each. Then gate circuit 4 samples the signals of the symmetrical square waves aporoximate to the phase of the color burst signal via the burst flag pulse among the signals delivered from circuits 2a, 2b and 2c each. Mixture 5 is given to the output between circuit 4 and selection circuit 5, 7 and 6, and the signals of different luminance levels are added 7. Then the output are mixed 9 between circuits 5 and 7. In such way, the information of the characters, patterns and others can be displayed on the color TV picture receiver after the color submodulation in a simple structure.
