Title: Improvements relating to colour television receivers
IPC: H04N9/455
Filed: 1965-09-27
Abstract: 1,118,465. Colour television. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 27 Sept., 1965 [8 Oct., 1964], No. 40962/65. Heading H4F. In a receiver for the PAL colour television system the chrominance carrier signal is modified in a stage 4 to produce a signal having a phase angle with respect to a reference axis <SP>1</SP>equal and opposite to that of the received signal, which modified signal is then compared in a phase comparator 7 with the unmodified signal from the preceding line, obtained via delay line 2, to obtain a signal U R  to control the phase of a datum carrier oscillator 9. The control signal is proportional to undesired phase errors imparted to the carrier signal by transmission conditions and is independent of the phase modulation due to chrominance information. By transferring delay line 2 to the same path as modifier 4 an alternative arrangement is produced in which the modified signal is phase compared with signal in the next succeeding line. The modifier 4 comprises a modulator in which the chrominance carrier is modulated by a signal of twice the frequency and the lower side-band selected from the resulting signal. As illustrated the double frequency signal is obtained from oscillator 9 by way of frequency doubler 11. The control signal controls the phase of oscillator 9 by means of reactance stage 8. The effect of the arrangement is to cause the output of oscillator 9 to vary in phase in accordance with the phase error of the chrominance carrier signal so that the oscillator output is always of the correct phase to demodulate the carrier. Oscillator 9 is also synchronized by the colour synchronizing signals which produce a signal over lead 13 to control reactance stage 8. In another arrangement (not described in detail) oscillator 9 is synchronized by the colour synchronizing signals and the control signal U R  controls a phase shifter connected to the output of the oscillator.

Abstract: 933,935. Television. GENERAL ELECTRIC CO. Ltd. Sept. 28, 1961 [Dec. 9, 1960], No. 42486/60. Class 40 (3). In a colour television picture reproduction system utilizing a tri-gun tube 18 (Fig. 2) to the cathodes of which luminance signals are fed and to the control grids of which colourdifference signals are fed the D.C. level of the latter signals is stabilized by meant of a clamp circuit 17 employing individual valves 22, 23, 24 (for the colour-difference signals) controlled by a source 33 of clamping pulses common to the three colour channels so that the relative D.C. levels are independent of variations in the amplitude of the clamping pulses. Because of the resulting common impedance (resistor 28) circuit 17 introduces a degree of matrixing of the input signals and this is taken into account by so proportioning the input signals to the circuit 17 and the luminance signals fed to the cathodes that the desired drive signals for the tube are obtained. As described, simultaneously produced E R  (Red), E G  (Green) and E B  (Blue) signals from a camera 10 are gamma corrected in respective circuits 11, 12, 13 and fed to a matrix 14 which produces a luminance signal E<SP>1</SP>Y=(0.30R+0.59G+0.11B) and two chrominance signals E<SP>1</SP> 1 =(- 0.827R + 1.000G - 0.172B) and E<SP>1</SP> 2 =(- 0.069R+0.799G - 0.730B).
