Abstract
The invention concerns a method for determining the quality of a video and/or television image signal. In diversity reception installations comprising several receivers, it is necessary to establish a criterion for assessing the reception signals, so as to select the receiver with the best reception. In order to determine the quality of a television image, the interfering impulses appearing in a line after a horizontal synchronization impulse are detected then their parameters are evaluated. The invention is applicable to television receivers, video recorders, diversity reception installations, in particular for mobile installations.
