Method, Reproduction Apparatus and System for Display of Stereoscopic 3D Video Information A method for displaying stereoscopic 3D video information comprising a 3D video stream and 3D overlay graphics, the method comprising the steps of: setting an initial reference plane to a certain point in z-space, wherein the 3D overlay graphics are displayed in a depth interval in z-space ranging from the reference plane to an upper threshold facing a viewer, determining a depth range in z-space for the stereoscopic display of the 3D video stream for a plurality of time codes, determining whether a depth conflict between the reference plane and the 3D video stream exists for the respective time codes, wherein a depth conflict is existing if the depth in z-space for any feature of the 3D video stream conflicts with the reference plane in z-space, determining a set of conflict intervals defined by the respective time codes for which a depth conflict exists, handing over the set of conflict intervals to a reproduction device, and adapting the reproduction of the 3D video stream or the 3D overlay graphics for time codes of the 3D video stream that are located in one of the conflict intervals so as to resolve the depth conflict between display of the 3D video stream and the reference plane.
