摘要： A supply voltage is developed in accordance with an on/off control signal of a remote receiver during a start-up interval and during a power-up mode of operation of a television power supply. During a standby mode of operation, the supply voltage is switched off. The supply voltage produces a supply current in an oscillator that produces a signal at a horizontal rate related frequency. The supply voltage also produces a base drive current in a switching transistor of a horizontal driver only during the start-up interval. During a power-up mode, a run supply voltage is coupled to the oscillator and to the driver.

摘要： A control circuit of a television receiver power supply is constructed using a plurality of transistors operating in a common base configuration. The base electrodes of each of the transistors is coupled to a common conductor rail line that maintains the collector currents in the transistors temperature compensated over a wide range of operating temperatures during normal operation power-up mode of the receiver. In a standby mode of the receiver, power dissipation in the transistors is reduced by applying an on/off control signal to the common conductor rail line that prevents the flow of the collector currents in each of the transistors. Consequently, the supply current requirement of the control circuit is reduced during the standby mode.

摘要： Non-inverting amplifier, with bandpass filter in regenerative feedback path, forms color reference oscillator in a color TV receiver. Phase shift circuit, responsive to an oscillator output, supplies signals to a first phase shifted signal amplifier, which shares a load with the non-inverting amplifier, and is subject to control by complementary outputs of a phase comparator functioning to compare the phase of an oscillator output with the phase of incoming color synchronizing bursts. A voltage comparator, responsive to the respective phase comparator outputs, is periodically enabled by field rate keying pulses. The voltage comparator output controls the charging or discharging of a capacitor during the keying intervals. A second phase shifted signal amplifier, responsive to the output of the phase shift circuit, and delivering its output to the oscillator's feedback path, is subject to control in dependence upon a comparison of a control voltage derived from the voltage held by the capacitor with a reference DC voltage.

摘要： Signals to be cored are applied to the inputs of a linear signal amplifier, and of a multistage limiting amplifier having cascaded input and output amplifying stages. A cored version of the signals, corresponding to the difference between a linearly translated version of the signals and a doubly clipped version thereof, is developed by a signal combiner responsive to the outputs of both amplifiers. A variable coring level control voltage controls the distribution of gain between the input and output amplifying stages, substantially without disturbing the overall gain of the limiting amplifier, which is set to match the overall gain of the linear amplifier. In an illustrative embodiment, the signals which are adjustably cored are horizontal peaking signals derived from the received luminance signal in a color television receiver. An automatic peaking control system associated with output of the adjustable coring circuit opposes changes in peaking level that might otherwise accompany coring level adjustment.

摘要： A DC coupled system for automatically controlling the high frequency peaking content of a video signal is disclosed. The system includes a DC coupled control path comprising a peak detector for developing a control voltage representative of the high frequency content of the video signal exclusive of video signal DC components, and is preceded by a video signal amplifier. A filter for shaping the frequency response of the control path is connected to the amplifier. A manually adjustable peaking control for controlling the DC bias of the amplifier is also connected to the amplifier. The filter and adjustable peaking control exhibit mutually independent operation, and are both connected to the amplifier via the same single terminal.

摘要： A circuit for generating a composite keying signal comprises a burst gate circuit and a voltage translating network in a color television receiver also including keyed signal processing circuits and means for deriving horizontal and vertical blanking signals and a horizontal sync signal from a composite color television signal containing a color burst component. The burst gate circuit responds to the horizontal sync signal to develop a burst gate pulse encompassing the burst interval. A voltage level developed by the translating network in response to the horizontal and vertical blanking signals is combined with the burst gate pulse to produce a composite keying signal. The composite keying signal comprises a first pulse component of a desired level as determined by the translating network and ocurring during the blanking intervals, and a second pulse cmponent as provided from the burst gate circuit, superimposed on the first pulse and encompassing the burst interval. Means are also included for inhibiting the output of the keying signal generator during picture intervals of the television signal, to prevent false keying of the keyed circuits in response to keying signals generated by the keying signal generator in the presence of spurious input signals occurring during picture intervals.

摘要： Brightness control apparatus for a video signal image reproducing system including a video signal processing channel, a kinescope driver for supplying video signals to an image reproducing kinescope, and a source of substantially fixed potential to which signals processed by the kinescope driver are referenced. A comparator senses the substantially fixed reference potential and a blanking level which occurs during periodic blanking intervals of the video signal, and provides an output control signal indicative of the voltage difference between the reference potential and the blanking level. The control voltage is applied to the video channel for translating the blanking level in a direction to minimize the voltage difference, to thereby establish the conduction of the kinescope driver during image intervals of the video signal at a level corresponding to a desired image black level condition when such condition is manifested by the video signal.

摘要： An image brightness control arrangement for a color video signal processing system including a plurality of amplifiers each responsive to luminance and separate color difference signals for developing color representative output signals. A brightness control (e.g., a potentiometer) also is included for varying a brightness determinative D.C. level of the luminance signal. A locally generated periodic keying signal, occurring during periodic image blanking intervals of the video signal and of a magnitude which may vary undesirably, is coupled to each of the amplifiers for establishing a reference level for the color difference signals, as described in U.S. Pat.

摘要： DC stabilization system for a color TV receiver includes three control loops, each including a keyed comparator for comparing a respectively different one of a set of blue, green and red color signals with a common reference voltage during keying periods determined by line rate keying of "backporch" timing pulses. The output of the keyed comparator responding to the blue signal adjusts the DC level of a luminance signal component used in color signal formation. The output of the keyed comparator responding to the red signal adjusts the DC level of an I color-difference signal component used for color signal formation. The output of the keyed comparator responding to the green signal adjusts the DC level of a Q color-difference signal used for color signal formation. The line rate keying pulse source is subject to field-rate blanking to preclude comparator keying during significant portion of received signal's vertical sync interval.

摘要： Color reference oscillator comprises a non-inverting amplifier, with positive feedback via a crystal filter linking its output and input. A quadrature phase shift network, coupled to the filter output, delivers phase shifted signals to a pair of independently controlled amplifiers. One of the controlled amplifiers is responsive to control voltage outputs of a burst-responsive phase detector so as to inject phase shifted signals into the oscillator loop, as and when required, to effect synchronization of oscillator with burst component of incoming color television signal. The second of the controlled amplifiers is responsive to a reference DC voltage and to a manually adjustable DC control voltage, and develops a phase shifted signal output, of a magnitude and polarity dependent upon the magnitude and sense of the difference, if any, between the respective DC voltages, for combination with the non-inverting amplifier's output. Variation of the manually adjustable control voltage effects an adjustment of the free-running frequency of the oscillator.
