Abstract
To achieve improved and, in particular, optimum deflection correction of television picture tubes the sawtooth signal from the horizontal or vertical oscillator which is conventionally subjected to a correction, is left uncorrected. Per line, the time relation of the digital video signal controlling the picture tube via digital-to-analog converters is changed with respect to the time relation of the video signals as reconditioned with the aid of a video processor, i.e., by the correcting value depending on the respective locus of an image spot on the screen. Accordingly, the deflection correction is not carried out by influencing deflection means, but by a corresponding correction of the time relation of the video signals with respect to their loci on the picture screen.
