Abstract
The invention relates a method of extracting synchronization signals from an input video signal (Csync) comprising horizontal synchronization pulses at the start of video lines, for generating a horizontal synchronization signal (Hsync), said method comprising:—a calculation step () for calculating the duration (D) of the video lines in said input video signal (Csync),—a forcing step () for forcing said input video signal (Csync) to an output level, said output level corresponding to the level of said input video signal (Csync) after the horizontal synchronization pulses, said input signal (Csync) being forced between the end of each horizontal synchronization pulse and a moment defined by a first percentage (X) of said line duration (D), for generating said horizontal synchronization signal (Hsync). Use: Extraction of synchronization signals.
