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: A device for encoding and a device for decoding a picture, respectively, and corresponding methods relating to the field of picture coding are provided. The devices are respectively configured to partition the picture into one or more slices, each slice comprising one or more tiles, and one or more slices holding coded picture data. Further, the devices are configured to encode the one or more slices holding coded picture data, thereby improving coding and decoding of pictures with uncoded buffer space.

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.
