Abstract: A video system comprises a first video device which transmits a video signal comprising image information and synchronisation information and a second video device which receives the composite video signal. The second device has a time base. For synchronising the two devices synchronisation information is extracted from the video signal received by the second Video device and from the time base of the second video device; a phase difference between the video signal received by the second video device and the time base of the second video device is determined based on the extracted synchronisation information; control information of a first type representative of the amount of the phase difference is transmitted to the first device; and in the first device the phase of the video signal is switched by a phase angle represented by the first type control information.

Abstract: The invention relates to a stereoscopic camera comprising means to facilitate the adjustment of its optomechanical parameters by an operator. To this end, it comprises storage means (16, 17) in order to store at least one stereoscopic image and a selection means (18) in order to selectively supply to the display means of the camera either the stored stereoscopic image, or the current stereoscopic image filmed by the 2D cameras (10, 11) of the stereoscopic camera.
