ABSTRACT:
DC stabilization system for color signal inputs to kinescope drivers of a color TV receiver (of a type employing AKB control) includes four control loops, one serving to adjust DC level of I color-difference signal, one serving to adjust DC level of Q color-difference signal, and two serving to adjust DC level of the Y (luminance) signal. One of the Y-adjusting control loops, employing a voltage comparator enabled only during periodic kinescope bias control intervals recurring at a field rate, is provided with an effective time constant which is short relative to the duration of a line interval. The other of the Y-adjusting control loops, employing a voltage comparator enabled only during backporch blanking portions of line intervals lying outside of the recurring kinescope bias control intervals, is provided with an effective time constant which is long relative to the duration of a line interval.
