Abstract
A television system includes a one-chip television signal processing IC including luminance and chrominance signal processing sections and character signal input terminals intended to receive character signals corresponding to the colored characters to be displayed by an associated display device and a character brightness control terminal intended to receive an adjustable DC control signal for setting the brightness of the colored characters. A blanking signal for blanking the video image is coupled to one of the character signal input terminals instead of a character signal, and an IC supply voltage corresponding to a black image level is coupled to the character brightness control terminal instead of an adjustable DC brightness control signal. The blanking signal is used for blanking the video image behind a displayed character body and also for emphasizing displayed characters, e.g., by 'edging' the character bodies. The blanking signal may also be used for blanking the entire video image at various times, such as during channel changes.
