ABSTRACT: Signal-dropout correction circuit for correcting video signal disturbed by signal dropouts. A dropout correction circuit is described. It comprises a dropout detector which compares a signal with a reference lever and controls a switch which connects an output of the circuit to a line memory, in order to insert a corresponding part of a preceding line during such a dropout. In order to enable the reference level to be selected as high as possible the color carrier is extracted before the video signal is applied to the dropout detector.
