摘要： a teletext processing unit for processing a text broadcasting data; a control unit(4) for generating color control signals(color, contrast, tint, and brightness); a color processing unit(7) for processing RGB colors from the teletext processing unit(6) and an image processing unit according to the color control signal(S1-S4). A brightness varying unit(8) is added to the apparatus for varying a brightness control signal(S4) from the control unit according to a surrounding luminance when a teletext broadcasting is performed by a teletext processing unit(6).

摘要： An average beam current limiter for a kinescope responsive to video signals coupled via a signal transmission channel(STC) comprises a source of control signals representative of average current drawn by the kinescope. When average beam current exceeds a predetd. threshold level by an amt. within a first range beam current, a corresponding control signal is coupled to the STC to vary the DC content of the video signal in a direction to limit beam current above the threshold level within the first range. When beam current exceeds the threshold level by a relatively greater amt. within a second range of current, a corresponding control signal serves to current within the second range.
