1. A method of encoding a 3D video data signal, the method comprising: in a processor, providing at least a first image of a scene as seen from a first viewpoint, providing rendering information for enabling a decoder to generate at least one rendered image of the scene as seen from a rendering viewpoint, providing a preferred direction indicator, defining a preferred orientation of the rendering viewpoint relative to the first viewpoint being different than the first viewpoint, and generating the 3D video data signal comprising encoded data representing the first image, the rendering information and the preferred direction indicator, wherein a preferred direction indicator is encoded in the 3D video data signal using at least one of the following options a preferred direction indicator is encoded for every frame, a preferred direction indicator is encoded for every group of frames and a preferred direction indicator is encoded for every scene, wherein the value of the preferred direction indicator is constant for one of a group of frames and a scene.
