Abstract: Apparatus for automatically controlling the bias of an image reproducing color kinescope in a system including a plurality of video driver states for supplying image representative video signals to respective intensity control electrodes of the electron guns of the kinescope. The output of each driver stage is coupled to an operating supply voltage via a load impedance. The electron gun currents (e.g., Cathode currents) are sensed during image blanking intervals of the video signal to provide respective control voltages representative of the electron gun blanking current levels.

Abstract: Reproducing kinescope with plural cathode electrodes and a common grid electrode, a kinescope driver amplifier arrangement is disclosed for supplying frequency selective video signal drive to the kinescope. The receiver also includes networks for providing wide bandwidth luminance (Y) and plural color (r, g,b) image representative signals containing low and high frequency components, as derived from a composite color television signal. High frequency components composite color television signal. High frequency componets (e.g., drived from the luminance signal) above a prescribed frequency are selectively processed in a grid signal path.

Abstract: A charge coupled device(CCD) comb filter arrangement is provided which is particularly suited for separating luminance and chrominance signal components in a color TV signal. Parallel paths of long and short CCD delay lines(26) (32) using a common clock drive are provided in which the difference in delay between the long and short lines determines the frequency intervals between the teeth of the comb substantially independently of factors of other than the clock frequency and the number of delay stages.

Abstract: The signal processor for a switched vertical deflection amplifier comprises a modulator stage which produces the pulse width modulated gating signals obtained by modulating horizontal rate pulses including a ramp portion at a vertical deflection rate. The gating signals control switches coupled between a source of horizontal retrace pulses and a capacitor for charging the capacitor with decreasing and increasing amounts of energy during respective first and second intervals during each vertical trace interval for producing a sawtooth current in a vertical deflection winding (51) coupled to the capacitor (50).

Abstract: The color temperature adjustment circuit for television CRT's provides compensation for variations between the electron guns, and between the efficiency of the various screen phosphors. Adjustment is achieved by processing in individual channels the color, brilliance and synchronisation signals. Each such channel has a two position switch, one position being for normal receiver operation and the second selectively rendering inoperative the colour and brilliance channels. A second video circuit operates independently of the normal synchronisation signal separation circuit (60), the output of this second channel feeding a synchronisation signal generator (62).
