Abstract
In a television receiver with a kinescope driver stage for providing video drive signals to an image displaying kinescope, a control circuit couples an auxiliary character information signal to a reference input of the driver stage, separate from a source of reference bias potential also coupled to the reference input of the driver stage. The intensity of displayed character information is related to the control circuit biasing, which is derived from a pre-existing local source of alternating current signal.
