Abstract: Successive values of a horizontal phase of a video signal are determined a predetermined integer number of video lines after the successive occurrences of vertical synchronization pulses. The successive values of a parity bit are updated according to the successive values of the horizontal phase. Indications on the parity of the fields are provided from the successive values of the parity bit.
