Motor vehicle operating device

For optimum videotex data coding, for error-free functioning of so-called descramblers and&mdash;not least&mdash;for the impression of improved detail resolution on the screen of a television set of displayed pictures, it is known to process the video frequency response by influencing the higher frequency components in the video signal spectrum. According to the invention, adaptation to a video frequency response sought is in each case carried out automatically by means of corresponding shifting of the vision carrier relative to the IF total transmission curve. The respective adaptation for the relevant television channel of the set is effected, in principle, by the addition of a corresponding correction value to the corresponding channel tuning voltage of the tuner.

Compensation of picture tube ageing effects

Recent circuit concepts inject measurement lines, for cutoff and drive control of the cathode current, into each color channel during the vertical frame blanking period. Owing to the physically dependent exponential beam current characteristic profile as a function of the cathode control voltage V,, the exponent &ggr; of the characteristic profile and the ratio of two cathode components I,and I,may be used to form control reference values for cutoff and drive control, this process being started in each case from a fixed value of the exponent &ggr; or of the ratio of the two cathode currents I,and I,. However, it has been found that, if a fixed value is assumed for the exponent &ggr; or for the ratio of the two cathode currents I,and I,, it is not possible to achieve an optimum result for displaying monochrome pictures. Thus, according to the invention, the exponent &ggr; is defined as a function of the color tube,The aim in this case is to reduce a &ggr;-dependent DC voltage offset u,to zero.

&ggr; matching of a video processor by means of three measured currents

A circuit for controlling the picture tube in a television receiver. In order to generate a high peak white on the screen of the picture tube, it is desirable to drive the output amplifiers at full output. Because of tolerances, for example in the cutoff calibration, the transparency of the picture tube glass, fluctuations in the input signal etc., driving the video output stages to full output may drive the output stages into saturation and disturbances in the form of so-called smears can occur in the picture. The present invention permits the output stages to be driven to full output as far as the highest peak white without the output amplifiers going into saturation and causing disturbances in the form of smears in the picture. In particular, the outputs of the output amplifiers are each connected via a diode to a common circuit point with a voltage such that the amplitudes of the output voltages of the output amplifiers do not exceed, in the direction of white, a prescribed value corresponding to peak white. In a development, the circuit point is connected to a control terminal, serving to limit the beam current, of a video processor supplying the color signals.

Circuit for controlling the picture tube in a television receiver

A circuit for automatically adjusting the beam current of a CRT to compensate for long term changes in the characteristics of the CRT upon the occurrence of an operational event of the CRT, and for avoiding producing unwanted lines in dark screen areas during current blanking includes an adjustment circuit for providing a reference control signal. A test line generator provides a test line pulse to the adjustment circuit upon the occurrence of the operational event. The beam current developed by the reference control signal is measured and an adjustment voltage is generated. A comparator receives the adjustment voltage and a reference voltage and provides a control voltage. A switch connects the test line generator and the control voltage to the adjustment circuit a preselected time after the occurrence of the operational event. A memory device stores the control voltage until the next occurrence of the operational event.

Circuit for the cut off regulation in a television receiver rendered

A circuit for regulating the color subcarrier amplitude in a video recorder used with a television receiver which employs overscanning of the electron beams for different modes of operation includes a regulating circuit for providing a regulating voltage representative of the amplitude of the color subcarrier. The regulating circuit includes a variable time constant circuit for switching from a short time constant during the overscanning to a long time constant immediately prior to ending the overscanning to change the regulating voltage in response to changes in the time constant. A variable amplifier is responsive to the regulating voltage to regulate the amplification of the color subcarrier in response to changes in the time constant.
