The system has a receiving module (3) for receiving a video signal, where the video signal comprises red, green and blue type color signals, three synchronization signals (SYNC) and a clock signal (CLK). An inlaying unit inlays a graphical recognition pattern in the video signal. A receiving unit is operated at sampling frequency, which is integral multiple of frequencies of the clock signal. The receiving unit comprises testing units (301, 302, 311, 312, 321, 322) for identifying synchronization information in a low voltage differential signaling signal and the pattern. |
