Title: Improvements in color television reception
IPC: H04N9/26
Filed: 1957-04-12
Abstract: 815,681. Television. RAIBOURN, P. April 12, 1957 [April 27, 1956], No. 12039/57. Class 40(3). In a colour television receiver for signals of the NTSC type and utilizing a single-gun " selfdecoding " tube 6 to the cathode K of which the complete detected video signal (i.e. the luminance signal together with the chrominance modulated sub-carrier) is supplied, the thirdharmonic gating of the tube beam consists of a train of blanking pulses supplied to the control grid G1 during portions of the sub-carrier cycle which relate to colours complementary to the primary colours of the system (e.g. Red, Green, Blue) and the width of such pulses is controlled as a direct function of the amplitude of the lowfrequency components of the chrominancemodulated sub-carrier. Such gating, as distinct from the known arrangement of gating the tube beam '' on " only during the occurrence of the primary colours in the sub-carrier cycle, results in an increase in brightness in the reproduced picture since the period during which the beam is " on " is increased-such period varying from 100 per cent of the duty cycle (i.e. zero blanking) for black/white reproduction, through intermediate values for unsaturated colours and to relatively low values for saturated colours only. In the arrangement shown the blanking pulses applied to Glare derived from the anode of a valve 26 to the control grid of which an oscillation of three times the chrominance subcarrier frequency is supplied and to the suppressor grid of which a signal proportional to the amplitude of the low-frequency components of the chrominance modulated subcarrier frequency is supplied, the latter being derived by peak detection in 30 of a narrow band of signals centred on the sub-carrier and selected by means of a band-pass filter 28. The signal supplied to the control grid (which is biased to conduct only during the positive halfcycles thereof) is phased so that the positive halfcycles occur during the occurrence of the complementary primary colours in the sub-carrier cycle and this, together with the control of the suppressor grid by signals proportional to the low-frequency colour signals results in negatively-going pulses being supplied to G1, the widths of which vary inversely as the saturation of the colours. Specification 757,071, [Group XL (a)], is referred to.
