FIELD: television. ^ SUBSTANCE: current circuit is meant for selective blocking of normal effect of circuit for modulation of speed of sweeping during screen reproduction, to prevent or weaken appearance of parasite images. In device having system for beam sweeping speed modulation and screen reproduction generator, generator selectively functions, dispensing symbols and graphics, which are applied to main video image. During operation of generator circuit for modulation of sweeping speed can by characterized by tendency to reproduce parasite images on screen. ^ EFFECT: broader functional capabilities. ^ 6 cl, 4 dwg |
