    Abstract: A method comprising: encoding pictures into a bitstream, the bitstream comprising at least two scalability layers, pictures being associated with access units and pictures being associated individually with one of the at least two scalability layers; indicating in the bitstream inter-layer prediction dependencies, indicative of direct reference layers, if any, of a first scalability layer and indirect reference layers, if any, of the first scalability layer; selecting an earlier picture in decoding order as a basis for deriving picture order count (POC) related variables for a current picture based on a pre-defined algorithm, the current picture being associated with a current scalability layer, wherein the earlier picture is the closest preceding picture, in decoding order, to the current picture among a set of pictures that are associated with the current scalability layer or any direct or indirect reference layer of the current scalability layer.

    Abstract: In an example embodiment, a method, apparatus and computer program product are provided. The method includes defining a plurality of depth layers of a depth map. At least one depth layer of the plurality of depth layers is associated with a respective depth limit. The method further includes determining, for the at least one depth layer, a respective texture view layer of a first picture. The method further includes deriving a measure of a respective texture property for the respective texture view layer. Selective filtering is applied to the respective texture view layer based on the measure of the respective texture property and the respective depth limit associated with the at least one depth layer.

    Abstract: The embodiments relate to a method for encoding two or more tensors. The method comprises processing the two or more tensors having respective dimensions so that the dimensions of said two or more sensors have the same number (510); identifying which axis of each individual tensor is swappable to result in concatenable tensors around an axis of concatenation (520): reshaping the tensors so that the dimensions are modified based on the swapped axis (530): concatenating the tensors around the axis of concatenation to result in concatenated tensor (540): compressing the concatenated tensor (550); generating syntax structures for carrying concatenation and axis swapping information (560): and generating a bitstream by combining the syntax structures and the compressed concatenated tensor (570). The embodiments also relate to a method for decoding, and to apparatuses for implementing the methods.

    Abstract: A method comprising encoding a bitstream comprising a base layer, a first enhancement layer and a second enhancement layer; encoding an indication of both the base layer and the first enhancement layer used for prediction for the second enhancement layer in the bitstream; encoding, in the bitstream, an indication of a first set of prediction types that is applicable from the base layer to the second enhancement layer, wherein the first set of prediction types is a subset of all prediction types available for prediction between layers, and encoding, in the bitstream, an indication of a second set of prediction types that is applicable from the base layer or the first enhancement layer to the second enhancement layer, wherein the second set of prediction types is a subset of all prediction types available for prediction between layers.
