摘要： In a video display, correction data for a digital convergence arrangement are stored in a first non-volatile memory. During power turn on procedure, the correction data are read out of and stored in a volatile memory. During each deflection cycle, the data stored in the volatile memory are successively read out and applied to an auxiliary convergence winding. When a parity error is detected in the read out data, an output and/or an input of a convergence amplifier is actively disabled to prevent a disturbance of a screen of the cathode ray tube.

摘要： A switchable digital filter interpolates distortion correction values. The distortion correction values together with interpolated distortion correction values are supplied as an output. Proper operation of the digital filter is disturbed by transient signals occurring during horizontal retrace. The digital output is converted to an analog convergence correction signal. The digital to analog converter has an operating frequency and generates a transient signal during horizontal retrace as the operating frequency increases due to an increased horizontal scanning rate. A low pass filter receives the analog convergence correction signal and generates an analog deflection signal. An auxiliary deflection coil is driven by the analog deflection signal. The digital filter is switched off during the horizontal retrace. The digital filter is thus protected from disturbance by the transient signal and the digital to analog converter is protected from exceeding a maximum operating frequency.

摘要： A memory and a switchable digital filter supply different numbers of digital distortion correction values. The supplied distortion correction values are converted to an analog distortion correction signal. A passive, analog low pass filter for the analog distortion correction signal generates an analog deflection signal. The low pass filter is optimized only for those of the analog deflection signals having a given sample rate. A controller varies the different numbers of the supplied distortion correction values to maintain the given sample rate of the analog deflection signal for different horizontal scanning rates. The controller selectively implements respective operating modes for different horizontal scanning frequencies in which no interpolated distortion correction values are supplied or different numbers of interpolated distortion correction values are supplied.

摘要： A grid correction circuit for a television receiver includes a first memory for storing correction values for correcting the deflection current of the television receiver. A second memory perodically provides a test signal to a correction coil to correct the deflection of the television receiver. A switch periodically selectively connects the first memory to the correction coil and a correction current flows through the correction coil. The switch also periodically connects the second memory to the correction coil and a test current flows through the correction coil. An impedance is responsive to the correction coil and produces a correction voltage and a test voltage in response to the correction current and the test current respectively. A comparator receives the test voltage and compares the test voltage to a reference voltage and provides an output voltage having a first level when the test voltage is below the reference voltage and a second level when the test voltage is above the reference voltage. A processor receives the output voltage and changes the correction voltage to incrementally reciprocate above and below the reference voltage by a preslected increment to maintain the correction voltage at substantially the same level as the reference voltage over a long time period.

摘要： A method and apparatus for obtaining correction values for convergence setting in video projection devices includes calculating the correction values for the individual video lines at least in part by interpolation between correction interpolation point values. The correction interpolation point values are in this case distributed in the form of a grid over the screen area of the video projection device. During the calculation of correction values for the video lines of a first field of the video frame, a respective set of two intermediate or final values for the interpolation is calculated, which set is applicable to neighbouring lines in different video fields, but in each case only one intermediate or final value is used for the convergence correction in the current video line. As a result, optimal convergence correction can be set for each video line without a high memory outlay and without high computing complexity.

摘要： A first input signal has successive zero amplitude crossings. A first comparator generates a first bilevel output signal responsive to the first input signal. The first comparator has a hysteresis characteristic which is switched on at each said zero crossing of the first input signal and switched off prior to each occurrence of the next following zero crossing. A second input signal has successive zero amplitude crossings and is displaced in phase relative to the first input signal. A second comparator generates a second bilevel output signal responsive to the second input signal. The hysteresis characteristic is switched on by level transitions of the first bilevel output signal and switched off by level transitions of the second bilevel output signal. The first and second input signals may be sinusoidal. The hysteresis characteristic may controlled by first and second flip/flops, which are set by the first bilevel output signal and reset by the second bilevel output signal.
