Title: Circuit arrangement for adjusting the black level of a video signal
IPC: H04N5/18
Filed: 1962-02-25
Abstract: 1,026,664. Television transistor gain-control circuits. FERNSEH G.m.b.H. Feb. 25, 1963 [Feb. 24, 1962], No. 7410/63. Headings H3T and H4F. A circuit is arranged to vary the black level S of a composite video signal waveform G, Fig. 4, comprising a picture component and a blanking component without altering the overall amplitude O of the signal. An original composite signal B of amplitude M is combined with auxiliary pulses H of equal amplitude to produce a new composite signal C which is applied through a variable gain device to produce a reduced signal of amplitude M<SP>1</SP>. This signal is then clamped at the peaks d of the auxiliary pulses and re-blanked by pulses A to produce a signal F. Finally, a clamping stage operates on the signal at a fixed level O with respect to the clamping level to derive signal G. Thus, as the variable gain device is adjusted the " set-up " L of the black level S with respect to the blanking level varies, but the overall signal level O remains constant. In a modification, Figs. 2 and 5 (not shown), intermediate signal transmission stages which are of unspecified form but do not change the signal are included between the variable gain device and the blanking stage. An additional stage is also included by which the auxiliary pulses H are offset by counter pulses of equal amplitude. A detailed circuit for the arrangement described with reference to Fig. 4 is shown in Fig. 3. The original signal B is combined with the auxiliary pulses H<SP>1</SP> in a mixer stage 3 and the new composite signal C applied through emitter follower stage 24 to the gain control device which comprises a potentiometer formed of a fixed resistor 26 and a voltage dependent resistor 27. The value of resistor 27 is adjusted by passing a variable current from a potentiometer 29. The highfrequency response of the circuit is compensated by a shunt inductor 33. The signal D<SP>1</SP> of reduced amplitude is clamped at the peaks of the auxiliary pulses by clamping stage 6 which is driven by pulses H<SP>1</SP> coincident with the auxiliary pulses. The signal is then re-blanked by pulses A applied to the emitter of stage 37 to produce waveform F which is applied to a clipper stage 51, 53. The base potential of transistor 53 is fixed by potentiometer 55, 56 and determines the clipping level and hence overall level O of the final signal G.
