Abstract: The invention relates to an apparatus for decoding 3D video data, the 3D video data comprising a plurality of texture frames and a plurality of associated depth maps, the apparatus comprising: a first texture decoder configured to decode a video coding block of a first texture frame associated with a first view; a first depth map decoder configured to decode a video coding block of a first depth map associated with the first texture frame; a depth map filter configured to generate an auxiliary depth map on the basis of the first depth map; a first view synthesis prediction unit configured to generate a predicted video coding block of a view synthesis predicted second texture frame associated with a second view on the basis of the video coding block of the first texture frame and the auxiliary depth map.

Abstract: An apparatus for processing 3D video data using inter-view prediction is described, the apparatus comprising a processor (201) configured to: obtain a reconstructed depth information value of a reconstructed depth information video coding block associated to a reference depth information map of a reference view, obtain a reduced range information associated to the reference depth information map; process a reconstructed distance information value to obtain an adapted reconstructed distance information value of the reconstructed depth information video coding block using a distance information value adaptation function, which is based on the reduced range information, and generate a predicted texture video coding block and/or a predicted depth information video coding block for a dependent view on the basis of the adapted reconstructed distance information value of the reconstructed depth information video coding block associated to the reference view.
