Abstract

Process for mobile reception of television signals in which an output signal (SA) is derived from n different (S1 . . . S5) and is supplied to the reproduction part of the receiver, the n input signals (S1 . . . S5) being weighted, the output signal (SA) being formed by summing of the weighted input signals, and the quality of each of the n input signals (S1 . . . S5) being evaluated using at least one given criterion for determining the adaptively determined weighting factors, characterized in that the n input signals (S1 . . . S5) are time-synchronized before their evaluation, summing and weighting, and the horizontal and/or vertical video synchronization pulses contained in the input signals (S1 . . . S5) are used for control of time synchronization.
