Abstract
A signal, method, system and computer program product is based on displaying at least two markers embedded within each frame of the video content. One of the at least two markers is displayed in a first half of each video frame and a second of the at least two markers is displayed in a second half of each video frame, the frame being split into the first and the second halves along a splitting line being perpendicular to an axis that is a refresh axis for a particular display screen. The markers are such that enable distinguishing whether a right-eye or left-eye frame is displayed.
