Claim:
1. A method for displaying stereoscopic 3D video information comprising a 3D video stream and 3D overlay graphics, the method comprising: retrieving a set of depth conflict intervals associated with the 3D video stream from a media source comprising the 3D video stream and the 3D overlay graphics, wherein the set of depth conflict intervals is provided together with the stereoscopic 3D video information, and wherein a depth conflict interval indicates a time span during which a minimum depth value of the 3D video stream falls within a depth range provided for presentation of the 3D overlay graphics, or during which the minimum depth value of the 3D video stream or a minimum depth value of the depth range provided for presentation of the 3D overlay graphics falls outside a comfort zone defined in an authoring process, wherein the comfort zone specifies a depth range in z-space for preferable presentation of the stereoscopic 3D video information, said time span being comprised between a first time and a second time, said first time and said second time are defined to be a time for which the minimum depth value of the 3D video stream equals a depth value of a reference plane of the 3D overlay graphics; and adapting a presentation of the 3D video stream or a presentation of the 3D overlay graphics for time codes of the 3D video stream that are located in one of the time spans indicated by the depth conflict intervals so as to resolve the corresponding depth conflict.
