Title: Improvements in and relating to a television receiver
IPC: H04N5/57
Filed: 1964-08-14
Abstract: 1,041,929. Television. BLAUPUNKRWERKE G.m.b.H. Aug. 14, 1964 [Aug. 16, 19631, No. 33372/64. Heading H4F. In a television receiver in which the contrast control is arranged in front of the output stage of the video amplifier, the video amplifier includes a preamplifier stage the gain of which is dependent upon the instantaneous D.C. level of the video signal and is arranged to be a high value which is substantially constant and substantially independent of the position of the variable contrast control for the synchronizing pulses of the received video signal, and at a low value which is dependent on the position of the variable contrast control for the picture portion of the video signal. These amplifier pulses are then fed to a synchronizing pulse separator connected to the output of the video amplifier. As shown, a video signal 6 is fed to the base of transistor 5, which forms part of the preamplifier stage, the base having a bias positive to earth taken from a tap earthed through a capacitor 7, terminal 10 carrying a positive operating voltage. Between the collector of transistor 5 and earth there is an adjustable potentiometer 13 serving as a contrast control, resistor 14, diode 15 and voltage divider 16, 17. The tap of potentiometer 13 is connected to the end stage of the video amplifier, i.e. pentode 18, the outputs 19 and 20 being connected, by means not shown, with a control electrode of a cathode ray tube and with a synchronizing pulse separator. The gain of the preamplifier stage depends on the total resistance in the collector branch and on the condition of diode 15. The voltage divider 16, 17 has at the junction of the resistors a no-load voltage which is only a little below the voltage of the back porch level of the video signal at the junction of the potentiometer 13 and the resistor 14, which is an inverted reproduction, Fig. 2 (not shown), of the corresponding portions of the video signal 6. Thus diode 15 is conducting 'during the actual picture portion of the video signal and there results at the collector of transistor 5 a small gain determined mainly by the effective resistance of potentiometer 13, since divider 16, 17 practically shortcircuits resistor 14. The synchronizing pulses, which are negative in the collector of transistor 5, are below the no-load voltage at the junction of resistors 16 and 17 and thus block the diode 15 so that resistor 14 is in series with potentiometer 13 thereby giving rise to a higher total resistance and thus a higher gain of the synchronizing pulses. Thus the signal mixture at the input of the end stage of the video amplifier contains amplified synchronizing pulses which are sufficient for blanking a synchronizing pulse separator. The receiver includes regulating means (not shown) before the video detector 1, 2, 3, 4 for maintaining the back porch of the video signal at a constant D.C. potential which is arranged to be approximately equal to the no-load or reference voltage at the junction of resistors 16 and 17.
