          I.3.1 depth intra contour prediction: A prediction of a partition pattern for a prediction block in a picture of a depth layer derived from samples of a picture included in the same access unit and in the texture layer of the same view.
          I.3.2 depth layer: A layer with a nuh_layer_id value equal to i, such that DepthLayerFlag[ i ] is equal to 1 and DependencyId[ i ] and AuxId[ i ] are equal to 0.
