A distortion-compensation method for a signal (S) that is transmitted in the blanking intervals of a video signal (CVBS) uses the received signal (S) to determine whether the signal (S) is subject to interference of a specific type. This interference is at least partially compensated for only when a specific limit value is exceeded. A separation stage according to the invention has a measurement apparatus (M) for detecting the presence of the specific type of interference.

Separation stage for separating a signal which is transmitted in the blanking intervals of a video signal and a distortion-compensation method for such a signal

The analog-to-digital converter device (,) provided for processing teletext signals is used for two purposes. In time slots in which no sync signal or teletext signal is separated from the video input signal (CVBS), the analog-to-digital converter device (,) is used for other tasks, e.g. for interrogating keypad inputs of an operator control unit (,).
