1. Method for encoding 3D video signals wherein a 3D video signal is encoded, the 3D video signal comprising a centre view video frame ( 61 ), a depth map for the centre view video frame ( 62 ) and an occlusion data frame for the center view video frame ( 63 ), wherein, under control of data in the depth map for the centre view, for the occlusion data frame data an indication means is generated for distinguishing functional data in the occlusion data frame from nonfunctional data prior to encoding the occlusion data frame ( 63 ).
