Abstract
A method for recovering a video signal uses an adaptive equalizer, the characteristics of which are adjusted to the conditions of a transmission channel by using the digital data signals that are concomitantly transmitted in addition to the analogue signal components in a video signal. This adjustment is then used for analogue signal components of the video signals. A teletext signal can advantageously be used for the adjustment.
